Why a motorsport team sponsored a motorsport team

Why a Motorsports Team Sponsored a Motorsport Team | PatientsCann UK® Skip to content Sponsorship Words Do Hurt Driving Out Cannabis Stigma Why a Motorsports Team Sponsored a Motorsport Team You might find it unusual for one motorsports team to sponsor another motorsport team. By PatientsCann UK® Motorsports Team Thomas Potter Racing Words Do Hurt Words Do Hurt campaign On this page Thomas Potter Racing Words that hurt patients Why we chose to support More than sponsors Best of luck, Thomas References You might also find it unusual that a medical cannabis not-for-profit has sponsored a 14-year-old racing driver. Ordinarily, you would be right. But that is exactly what we have done, and for a very good cause. The driver Introducing Thomas Potter Racing Thomas Potter is a 14-year-old racing driver competing in the Fiesta Junior Championship, following a successful karting career that included more than 100 race wins and six championships. However, Thomas Potter Racing is about far more than results on the track. Thomas has used his growing motorsport platform to support children and adults affected by bullying and poor mental health. His experiences inspired the Words Do Hurt campaign, which has been raising awareness of bullying, mental health and the importance of asking for help since 2020. Thomas experienced negativity, abuse and hurtful comments while pursuing his motorsport ambitions, including criticism linked to competing on a limited budget. Rather than allowing those experiences to drive him away from the sport he loved, he used them to help others who were going through similar situations. The campaign carries a simple but powerful message: Words do hurt. Words Do Hurt campaign Names added to the Words Do Hurt race car, Thomas Potter Racing. A Words Do Hurt campaign message: bullying costs lives. That message is displayed through Thomas’s racing, campaign vehicles, event appearances and work within the community. The project aims to use motorsport to start conversations in schools, colleges, race paddocks and community spaces about bullying, mental health and kindness. Thomas also invites people affected by bullying to add their names, or the names of people they want remembered or represented, to his vehicles. In doing so, every name becomes part of the campaign and travels with the team. A shared experience Medical Cannabis Patients Know That Words Hurt The experiences of medical cannabis patients are obviously different from those of a young racing driver facing bullying. However, the central message of the campaign will feel painfully familiar to many people in our community. Medical cannabis patients know first-hand that words do hurt. Patients can receive negative comments simply because of the medicine they have been legally prescribed. They may be called drug users, addicts or criminals, even when they are following specialist medical advice and using their treatment responsibly. A prescription can be dismissed as an excuse. A patient’s medical condition can be questioned. The smell of prescribed cannabis flower can cause strangers to make immediate assumptions about somebody’s behaviour, character or ability. These are not harmless words. They can make patients afraid to use their medicine in public, disclose it at work or speak honestly about their treatment. They can leave people feeling ashamed of something that is part of their healthcare. PatientsCann UK® exists to challenge those assumptions, provide practical support and ensure patients do not have to face them alone. Our motorsport team carries that mission onto the track by Driving Out Cannabis Stigma, promoting visibility and fair, evidence-based access for legally prescribed patients. The Words Do Hurt campaign and Driving Out Cannabis Stigma come from different experiences, but they share an important principle: Nobody should be defined or driven out of something they love by the words and assumptions of other people. PatientsCann UK® The decision Why We Chose to Support the Campaign When we learned more about Thomas, his racing and the purpose behind Words Do Hurt, supporting the campaign felt entirely natural. This was not about one motorsport team paying to place its logo beside another racing car. It was about two motorsport projects supporting a shared belief that the sport can be used to make people feel seen, represented and less alone. Sal Aziz, founder of the PatientsCann UK® Motorsports Team and Director of PatientsCann UK®, therefore personally funded a sponsorship position to support Thomas Potter Racing and the Words Do Hurt campaign. We are absolutely delighted that PatientsCann UK® Motorsports Team and Driving Out Cannabis Stigma appears on the team’s partners banner. The words “Cannabis Patients” have been added to the TPOT, ensuring that our community is represented alongside others who have been affected by bullying, hurtful language and stigma. The words “Cannabis Patients” added to the TPOT, Thomas Potter Racing. PatientsCann UK® on the Thomas Potter Racing partners banner. Those two words represent thousands of people. They represent patients who have been judged because of a smell. They represent people who have hidden their medication because they feared how others might react. They represent patients who have been excluded from work, volunteering, sport or ordinary public life because somebody saw the word “cannabis” and stopped seeing the person. Having “Cannabis Patients” written on the TPOT is a small but meaningful act of visibility. It says that our community belongs within this conversation and that stigma against patients should never be dismissed as harmless banter. Visibility Motorsport Can Carry More Than Sponsors A racing car usually carries the names of businesses, products and commercial partners. Thomas Potter Racing demonstrates that it can carry something more. It can carry people’s stories. It can carry the names of those who have been hurt. And it can carry a message into paddocks and communities that might otherwise never hear it. The Words Do Hurt campaign uses motorsport as a starting point for conversations about bullying and mental health, and Thomas’s story encourages young people to ask for help and continue pursuing their ambitions. That is something PatientsCann UK® is proud to stand beside. We know from our own work that visibility

Why We Started a Motorsports Team

Why a Medical Cannabis Not-for-Profit Started a Motorsports Team | PatientsCann UK® Skip to content Founder’s story Medical cannabis & motorsport Driving Out Cannabis Stigma Why a Medical Cannabis Not-for-Profit Started a Motorsports Team Before I knew medical cannabis was legal in the UK, motorsport was already my life. By Sal Aziz PatientsCann UK® Motorsports Team Founder’s story Team launch · Thruxton On this page Getting through the gate Becoming a patient When my case became policy Finding another route Why I have to race References One of my earliest racing memories is being told off for swearing after losing on Need for Speed: Underground. In my defence, I was only replicating my father! A few years later, he introduced me to Formula 1 after Lewis Hamilton joined the grid. I began watching properly in 2008 and was immediately hooked, waking at the crack of dawn when needed to see every race live. The highlight was Brazil 2008. My father walked out during the final lap, believing the championship was over, moments before Martin Brundle exclaimed: “Is that Glock?!” I had to scream for him to come back. I wanted to be part of that world, but racing appeared impossibly expensive. Even arrive-and-drive karting was beyond my budget. Then I discovered marshalling. Getting in Getting Through the Gate In 2021, I attended American SpeedFest at Brands Hatch. COVID restrictions meant unusually small crowds, giving the freedom to explore. Watching the marshals made me realise there was no reason I could not join them. I volunteered and was immediately hooked. Driving onto a circuit for the first time, even at 30 mph to reach my post, felt momentous. I was finally part of motorsport rather than watching from behind a screen or spectator fence. I went on to marshal events ranging from grassroots racing at Anglesey to the British Touring Car Championship and Goodwood Festival of Speed. I can even add “told Gordon Ramsay where to park at Goodwood” to my CV. Sal marshalling at Goodwood, as seen on Sky Sports F1. (Image source: Sky UK, used for illustrative purposes under Fair Dealing). “Told Gordon Ramsay where to park at Goodwood.” (Image source: Sky UK, used for illustrative purposes under Fair Dealing). I also competed in car trials, taking my Daewoo Lacetti off-road to see how far it could travel through marked sections. It was not Formula 1, but it was affordable, competitive and enormous fun. Author competing in a car trial (Image source: Woolbridge Motor Club, used for illustrative purposes under Fair Dealing). Treatment Becoming a Patient After a road trip through the Netherlands and an eventual drug-driving investigation in which I was found to be below the applicable limit, despite testing a wide range of cannabis products, I began exploring medical cannabis through the proper clinical route. My initial consultation took place on a Saturday morning at Silverstone before a day of marshalling. Once I began treatment, I noticed immediate improvements. Chief marshals commented positively on my performance. I completed the required health declarations and passed my flag assessment while openly prescribed medical cannabis. Author flag marshalling at the NASCAR Whelen Euro Series (Image source: GP1, used for illustrative purposes under Fair Dealing). Flag marshalling requires concentration, communication and rapid decisions in a safety-critical environment. I performed that role successfully and was excited to return to Goodwood for a second year, this time in the Supercar Paddock. Then a member of the public reported a marshal using cannabis. The report The Report That Began With a Smell I immediately acknowledged that the cannabis was mine and explained that it was legally prescribed for anxiety. I expected that explanation to resolve the concern. Instead, I was removed from post while senior Motorsport UK personnel were contacted. I was eventually permitted to continue in the lower-risk Supercar Paddock while the matter was reviewed. No performance failure or near miss had prompted the intervention. My medicine had become visible because of its smell. An odourless tablet may remain private. Cannabis flower can announce a patient’s treatment before they choose to discuss it. Smell is not evidence of impairment, but it can activate assumptions inherited from cannabis prohibition. That report eventually became much bigger than my individual case. Policy When My Case Became Policy In February 2024, Motorsport UK introduced Version 1 of a new signing-on declaration. It asked officials and marshals to confirm that they did not have disabilities or mental-health conditions, use drugs on the WADA Prohibited List, or take medication that might affect their duties. Motorsport UK later explained that the change followed reports during 2023 involving physical capability, mental health and the “substance use of colleagues”. I recognised myself in two parts of that explanation. Anxiety was my declared mental-health condition. Prescribed cannabis was my treatment, but it was apparently being framed as “substance use”. Although I was not named, the description reflected the defining features of my case. Version 1 of the officials declaration. Version 1 backfired horribly. Disabled volunteers and marshals taking medicines including blood thinners and asthma treatments began questioning whether they were still eligible. Medical cannabis was also independently identified as a problem. Within days, Motorsport UK issued Version 2, returning to a more sensible functional question: did the person’s condition or treatment adversely affect their duties? Version 2 of the officials declaration. But medical cannabis remained explicitly prohibited. My interpretation is that Version 1 attempted to capture cannabis through broad language about mental health, medication, “substance use” and the WADA list without initially announcing a cannabis-specific ban. When that language affected too many other volunteers, it was reversed, but cannabis patients remained excluded. I cannot prove the private intentions of those who wrote the policy. What I can say is that my case was followed by Version 1, the backlash, Version 2 and ultimately a categorical medical cannabis prohibition. Motorsport UK Public UK Licence Suspensions Register.

Race Report Thruxton Retro

Race Report: Thruxton Retro, 4 July 2026 | PatientsCann UK® Skip to content Race report Thruxton Retro Team launch Race Report: Thruxton Retro, 4 July 2026 The PatientsCann UK® Motorsport Team successfully launched at Thruxton Retro on 4 July 2026, with founder Sal Aziz completing 15 drag-racing runs in his Vauxhall Insignia estate. By PatientsCann UK® Motorsports Team Race report Thruxton, 4 July 2026 15 runs completed On this page Preparing the car Arrival at Thruxton A green light Racing through the middle Fifteen runs Just the beginning References After securing a NORA Motorsport licence with his medical cannabis prescription declared, Sal immediately began looking for an opportunity to return to competitive motorsport. Thruxton was the natural choice. It was the circuit where Sal had first entered motorsport as a marshal, making it the perfect place to relaunch his motorsport career from behind the wheel. The build Preparing an Unlikely Race Car Preparation for the event was suitably grassroots. Sal crudely applied a cannabis-themed livery to his Vauxhall Insignia estate before we posted a teaser on social media. Despite the appearance, we were generating attention before the car had even reached the start line. The teaser: a cannabis-themed livery applied to the Vauxhall Insignia estate. Livery detail: a sports team for cannabis patients. The Insignia was not built for drag racing. It is a diesel estate, complete with a roof box, rather than one of the specially prepared machines normally associated with the drag strip. The team knew the Insignia was unlikely to be competitive against dedicated racing machinery. The first objective was simply to take part. A diesel estate with a roof box in the paddock, among purpose-built machinery. Race day Arrival at Thruxton Sal drove to Thruxton feeling the familiar mixture of excitement and nerves that accompanies any motorsport event. This time, however, those emotions were amplified by everything he had experienced in the sport. This was more than his first drag-racing event. It was his return to competitive motorsport as an openly prescribed medical cannabis patient. It was also the public launch of a team created to challenge the stigma and exclusion patients continue to experience. On arrival, event staff were understandably surprised to discover that the Vauxhall Insignia estate with a roof box was there to race. But one of the attractions of a Run What You Brung event is contained in the name: almost anything can be raced. Sal was directed to Thruxton’s runway, which had been transformed into a drag strip for the event. After signing on, the Insignia passed scrutineering and was cleared to take part. The unlikely race car was ready. Thruxton’s runway, transformed into a drag strip for the event. Launch A Green Light for the Team Sal drove into the staging area and joined the queue alongside a remarkable mixture of machinery. The entry included purpose-built drag cars, powerful performance vehicles, modified classics and ordinary road cars. As he moved towards the front of the queue and began staging at the lights, the significance of the moment finally sank in. To an observer, it may have looked like somebody preparing to drive an estate car quickly down a straight runway. To Sal and PatientsCann UK®, it represented something far greater. A medical cannabis patient who had been excluded from one pathway into motorsport had found another. He had declared his prescription, obtained a licence, passed scrutineering and reached the start line through the relevant processes. The lights changed. Sal accelerated down Thruxton’s runway. With that first green light, the PatientsCann UK® Motorsport Team was officially launched. Staging at the lights on Thruxton’s runway. The PatientsCann UK® Motorsports Team launch at Thruxton Retro. Symbolism Racing Through the Middle The location made the moment especially symbolic. Thruxton’s runway sits inside the main circuit. While Sal completed his runs under the NORA and Straightliners framework, Motorsport UK-regulated activity was taking place on the circuit around him. He was literally racing in the middle of the motorsport environment from which prescribed medical cannabis patients had been excluded under a different governing system. Same patient. Same prescription. Same condition. Different governance. PatientsCann UK® Motorsport Team The contrast demonstrated why PatientsCann UK® believes that transparent, evidence-based participation processes are possible. Safety remains essential, but automatic exclusion is not the only way in which a governing body can respond to legally prescribed medication. The results Fifteen Completed Runs 15 Completed runs 11.07s Best time 64mph Top terminal speed Once the first-run nerves had settled, Sal returned to the staging lanes repeatedly throughout the day. He raced against everything from specialist drag machinery to conventional road cars. Unsurprisingly, the diesel estate was not troubling the fastest competitors, but outright performance was never the primary objective. The official results record 15 completed runs. Sal’s best time was 11.07 seconds, with his runs generally finishing at between 61 and 64 mph. His highest recorded terminal speed was 64 mph. More importantly, Sal participated consistently throughout the event while managing and using his legally prescribed medication. One event cannot establish that every medical cannabis patient is suitable for every motorsport role. Patients, roles and circumstances differ. However, the day demonstrated that a prescribed patient could disclose their medication, follow a governing body’s process and participate repeatedly in a live motorsport environment. One of 15 completed runs down Thruxton’s runway. Perspective More Than a Result There were no trophies for the PatientsCann UK® Motorsport Team at Thruxton Retro, and the Insignia estate did not suddenly become a thoroughbred drag car. The achievement was reaching the start line at all. Each completed run made medical cannabis patients visible within motorsport for the right reasons: participating openly, following the rules and contributing to the event alongside everyone else. The day also showed what accessible motorsport can look like. Sal did not arrive with a purpose-built car, a professional crew or a huge racing budget. He arrived in his everyday Vauxhall estate with a homemade livery and a roof box. And he raced it.

Psychiatric Patients Left in the Dark

Medical cannabis clinics refusing psychiatric patients | PatientsCann UK Skip to content News & Analysis Patient Rights Your Voice Counts Left in the dark: are private cannabis clinics turning their backs on psychiatric patients? Since a landmark coroner’s finding and the launch of Oliver’s Law, some private clinics appear to have swung from open doors to closed ones. We are hearing from patients who have been refused, discharged or flagged, often without a clear reason or a chance to reply. Here is what is happening, why it matters, and exactly what you can do.

Safety and fairness Safe prescribing matters. So does the right to an individual assessment, accurate records and a fair review. You have rights You can see your records, correct mistakes and be heard. This page shows you how, step by step. The shift From open doors to closed ones For years, private medical cannabis clinics built their reputations on access and care. They advertised low barriers to entry and a compassionate approach to conditions the NHS often struggles to manage. For many patients, that promise was real, and life-changing. Recent months tell a more worrying story. Following greater regulatory pressure and a coroner’s report about prescribing safety, some clinics appear to have moved into a defensive crouch. Rather than working with patients to deliver safe, individual care, a number seem to be quietly closing the door on people with a mental health history, sometimes the very people who were welcomed a year or two ago. We want to be clear and fair. Some caution is understandable, and safe prescribing is not optional. But caution should mean better assessment, not blanket exclusion. When a clinic refuses or discharges someone without a proper look at their situation, and without a chance to reply, that is not safety. That is a patient being left in the dark. A pattern reported across the community This is not about a single clinic. Patients sharing their experiences on platforms such as Reddit and Facebook describe a wider trend, and while every case is different, the themes are strikingly consistent. These are patients’ own accounts, not statements from the clinics. Three concerns come up again and again: Screening at the door Some applicants say that declaring a mental health condition now brings a high chance of rejection, particularly for new patients. Misread records Others report being turned down over old or miscategorised GP notes, then having to file a Subject Access Request and wait weeks just to prove the notes were wrong. Lost continuity Some long-term patients say they have suddenly lost access to a settled prescription, leaving them without the continuity of care they relied on. Clinics patients have raised similar concerns about Curaleaf Medicann Mamedica Integro Patients have described experiences like these with the clinics listed above on public platforms such as Reddit and Facebook. These are patients’ own accounts rather than statements from the clinics, individual circumstances vary, and this list reflects what we have seen so far.

None of them replied by the time we published, and we will gladly add or update their responses if they get in touch.

Share your experience If this has happened to you, please know it is not a reflection of your worth as a patient or a person. A refusal is a decision about a process, and processes can be questioned, corrected and appealed. The background Oliver’s story, and why clinics are reacting To understand the change, it helps to understand what came before it. Much of the current caution traces back to one deeply sad case, and to the campaign his family began in his memory. Oliver Robinson was 34. He lived with recurrent depression and a diagnosed dependency on cannabis. What happened to Oliver, and the inquest that followed, led to the first finding of its kind in the UK. We share the timeline below with care and respect for his family. Apr 2022 A prescription after one video call After a single video consultation, Oliver was prescribed high-strength medical cannabis for depression. Reports state the clinic relied on GP records printed around nine months earlier and did not contact his other treating psychiatrists first. Curaleaf disputes parts of this account and says the decision was approved by a multidisciplinary team; see what Curaleaf says. 2022-23 His health declined Over around 18 months his mental health grew more fragile. His healthcare professionals and family saw the cannabis as an obstacle to his recovery, and the prescription was seen to reinforce a dependency rather than easing it. Nov 2023 Losing Oliver On

SkunkyGassySulphurousPungent About What is 3-Methyl-2-butene-1-thiol? 3-Methyl-2-butene-1-thiol is the molecule most responsible for the strong, skunky smell people link with cannabis. It is often called prenylthiol. In 2021 a research team led by Iain Oswald pinpointed it as the number one skunk odorant in the plant. It carries a small chemical part called a prenyl group. This same building block turns up all over the cannabis plant, which may be why the smell feels so specific to cannabis. What the research says The Science Using a very sensitive method (two-dimensional gas chromatography with sulphur detection), the team measured this compound across many cultivars. The more of it a plant had, the more strongly people rated its skunky smell. It is powerful in tiny amounts. Even at a few parts per billion the nose picks it up easily, which is why a little goes a very long way.

Its role in the smell Part of the Whole On its own it smells purely skunky. Mixed with the fruity and piney terpenes, it helps give each cultivar its signature aroma. It sits alongside terpenes and cannabinoids as part of the plant’s full character. Good to know A Note on Safety 3-Methyl-2-butene-1-thiol is an aroma compound, present in cannabis in trace amounts. It is not a medicine and has no dose of its own. What matters for you is the whole product and how it is prescribed. Always choose and adjust your medicine with your prescriber and pharmacist, never by smell alone. Questions 3-Methyl-2-butene-1-thiol: Common Questions Is this what makes cannabis smell skunky? Yes. Research from 2021 found that 3-methyl-2-butene-1-thiol is the main molecule behind the classic skunky smell. The more a plant makes, the skunkier it tends to smell. Is it related to skunk spray or garlic? It belongs to the same broad family as the smelly molecules in skunk spray and garlic, called volatile sulphur compounds. That shared family is why all three can smell so strong. PreviousDimethyl trisulphide NextPrenyl thioacetate Back to full Sulphur Compounds Guide Important: This page is for education only.

Prenyl thioacetate is a close chemical cousin of the main skunk molecule. It carries the same prenyl building block, with a small acetate group added. It was described as part of the prenylated sulphur family found in cannabis. Its smell leans gassy and fuel-like. It is one of the compounds thought to sit behind the “diesel” or “gas” character that some cultivars are known for. What the research says The Science Like the other members of this family, it appears in very small amounts and needs sensitive sulphur-detecting equipment to measure. It tends to rise and fall alongside the main skunk molecule as the plant matures and is cured. Because it is so new to science, most of what is known is about its smell rather than any effect in the body.

Each corner and line-end is a carbon atom. The yellow S marks sulphur, the atom that gives this whole family its powerful smell. GarlicAlliaceousSavouryOniony About What is Diprenyl sulphide? Diprenyl sulphide is built from two prenyl groups joined by a single sulphur atom. That shape is very close to the smell molecules garlic makes, which use two allyl groups instead of prenyl. Its smell is more garlic and onion than skunk. It is one of the compounds that first made scientists notice how much cannabis and garlic have in common. What the research says The Science Garlic’s sulphur compounds have been studied for years for possible heart and blood-vessel benefits. Because cannabis makes such similar molecules, researchers have raised the hopeful question of whether cannabis sulphur compounds might one day show benefits of their own. This is an early idea, not a proven fact. So far the science here is about smell and structure, not about treating any condition. Aroma snapshot How Diprenyl sulphide Smells Garlic & savoury family GarlicAlliaceousSavouryOniony Smell strength: Very potent Rich and savoury; carries clearly even at low levels. You might also smell it in: Garlic, onions, leeks and chives, which build their smells in a very similar way. Its role in the smell Part of the Whole Brings a savoury, garlicky layer to a cultivar’s aroma. It is one of the compounds that ties the smell of cannabis to the smell of the kitchen. Good to know A Note on Safety Diprenyl sulphide is an aroma compound, present in cannabis in trace amounts. It is not a medicine and has no dose of its own. What matters for you is the whole product and how it is prescribed. Always choose and adjust your medicine with your prescriber and pharmacist, never by smell alone. Questions Diprenyl sulphide: Common Questions Why does some cannabis smell like garlic? Compounds like diprenyl sulphide are built much like the smell molecules in garlic and onions. When a plant makes more of them, it can take on a savoury, garlicky edge. Does that mean cannabis has garlic’s health benefits? Not proven. The molecules look alike, which is why researchers are hopeful, but no study has yet shown that cannabis sulphur compounds share garlic’s effects.

Each corner and line-end is a carbon atom. The yellow S marks sulphur, the atom that gives this whole family its powerful smell. GarlicOnionySavouryAlliaceous About What is Diprenyl disulphide? Diprenyl disulphide is like diprenyl sulphide but with two sulphur atoms joined together in the middle. That extra sulphur makes the smell deeper and longer-lasting. It is a near mirror of diallyl disulphide, one of the most studied smell molecules in garlic. The main difference is the prenyl group in place of garlic’s allyl group. What the research says The Science Diallyl disulphide from garlic has been looked at for possible effects on blood pressure and blood vessels. The close match with diprenyl disulphide is what makes the cannabis-and-garlic comparison so striking. It is important to be clear: looking alike is not the same as acting alike. This stays a hopeful research direction, not a health claim. Aroma snapshot How Diprenyl disulphide Smells Garlic & savoury family GarlicOnionySavouryAlliaceous Smell strength: Very potent Deep and long-lasting; the double sulphur bond makes it cling. You might also smell it in: Cooked garlic and onion, which are rich in these two-sulphur “disulphide” smells. Its role in the smell Part of the Whole Adds a deep, clingy, savoury base note to the aroma. Two-sulphur compounds like this one tend to linger longer than lighter smells. Good to know A Note on Safety Diprenyl disulphide is an aroma compound, present in cannabis in trace amounts. It is not a medicine and has no dose of its own. What matters for you is the whole product and how it is prescribed. Always choose and adjust your medicine with your prescriber and pharmacist, never by smell alone. Questions Diprenyl disulphide: Common Questions What is the garlic molecule it copies? Diallyl disulphide. Garlic’s version uses an allyl group; the cannabis version uses a prenyl group. Otherwise they are built the same way, with two sulphur atoms in the middle. Is this why some cannabis smells strongly of garlic? Two-sulphur compounds like this one are deep and clingy. When a plant makes more of them, its savoury, garlicky side becomes easier to notice.
