Medical Cannabis (Access) Bill — House of Commons, 2021-12-10
Topic: Health
Jeffrey Smith (Labour, Centre-left): The hon. Gentleman makes a really important point, and I agree. I do not agree with everything that the devolved Administration in Scotland do, but they do have an approach to these sorts of issues that is more focused on harm reduction and evidence than perhaps we have in England Cannabis-based medicines are already approved as a treatment for a small number of medical conditions. Currently, the National Institute for Health and Care Excellence guidelines recommend four licensed cannabis-based medical products that can be prescribed in the UK. I will talk about the terminology in a moment, but there are two THC-based medicines—dronabinol, which is licensed for appetite loss in AIDS patients and as an antiemetic in chemotherapy, and nabilone, which is a synthetic cannabinoid medicine licensed for nausea in individuals receiving chemotherapy. There is also Sativex, a combined THC and CBD medicine, which is licensed for muscle spasticity in multiple sclerosis patients, and Epidiolex, a CBD-based medicine—it is 99.8% CBD with less than 0.1% THC—for the two rare childhood epilepsies, Lennox-Gastaut syndrome and Dravet syndrome I am referring to THC and CBD; it might be helpful if I say a few words about terminology, and about the nature of cannabis, ahead of my next remarks about the proposals in the Bill. The cannabis plant is made up of something like 147 cannabinoids. They are the compounds that act on the cannabinoid system in the human body. There are also over 100 terpenes, which are aromatic compounds; flavonoids, which are pigments; and four other minor sets of compounds, so it is quite a complex botanical plant The complexity of the plant and its compounds is part of the issue that I will try to explain shortly, but the two main types of compounds that I am referring to are tetrahydrocannabinol, or THC, which is the psychoactive ingredient—very broadly and slightly simplistically, that is the ingredient that produces the high that recreational users experience, but it is also a painkiller—and cannabidiol, or CBD. Broadly, CBD has a more sedative effect—a kind of chill-out effect CBD on its own is legal in many countries, including this one; it is the THC content that makes cannabis illegal for recreational use in many countries. Different strains of cannabis plant have different balances of THC and CBD, and cannabis medicines do too. For example, Epidiolex, which is one of the most used medicines for severe epilepsy, is overwhelmingly CBD and has a very small amount of THC. Sativex has a higher proportion of THC. That is important because different treatments and balances work for different patients, and sometimes people have to adjust and tweak their treatment to find out what is right for them. If I refer to full-spectrum cannabis extract, that is a cannabis compound concentrate that preserves the full cannabinoid and terpene contents of the raw cannabis plant, including CBD, THC and other compounds. That is the plant, which is the basis of the medicine I want to provide three case studies of the real-life effect of cannabis-based medicines. Probably the most famous case is Alfie Dingley and his mum Hannah Deacon, whose campaign for access to medical cannabis helped to change the law in 2018. Alfie was perfectly healthy until he was four months old, when he became constantly sick and began having seizures. The seizures continued for months and he lost every skill he had developed. He was diagnosed with auto-immune epilepsy. The amount of time between Alfie’s clusters of seizures shortened as he got older. By the time he was five, they were happening every week. Each time, he needed up to five doses of intravenous steroids, which had a really negative effect on his personality and behaviour. Eventually, Alfie was diagnosed with a rare epilepsy syndrome which affects only nine known boys worldwide. There are slightly more girls with the syndrome, but only nine known boys in the world Hannah, Alfie’s mum, was desperate for a solution. She researched anything that might help and came across medical cannabis, so she learnt about the human cannabinoid system and cannabis medicines. At the time, Alfie’s doctors were telling her that regular steroids would eventually kill him, so to Hannah, cannabis medicines seemed like his only chance. She began the campaign for Alfie to have a prescription of cannabis medicines in the UK, where they were illegal at the time Once the family had raised enough money, they moved, in September 2017, to the Netherlands, where they could get medical cannabis legally. There they gave Alfie an oil prepared from Bedrolite, which is made by the Dutch company Bedrocan. That is a standardised strain of cannabis plant, with full extract CBD oil. Over the next three months, Alfie’s seizures became less frequent. They added THC oil called Bedica, also made by Bedrocan, under the guidance of their paediatric neurologist. Alfie went without seizures for 40 days. When he did have the clusters, they were less intense and were controlled much more easily. His cognitive development improved greatly Living abroad, however, was really hard for the family. After five months they ran out of money, so they had to come back home to the UK. In the UK, they had to fight for a prescription that contained both CBD and THC. Eventually, as a result of the campaign led by Hannah and other families, and under immense pressure from those desperate families, the Government agreed to change the law to make medical cannabis legal. Alfie finally received an NHS prescription for the products he had found so beneficial in the Netherlands in November 2018. It is still one of only three prescriptions in the UK, and his family had to go through an unusual process and special approvals to get that medicine. Three years later, Hannah has recently reported that Alfie has not had a seizure in over 500 days. Before his medical cannabis treatment, he was having 150 fits a week. Although cannabis medicines are not a silver bullet for everyone, they have been absolutely life-transforming for Alfie, Hannah and the rest of the family. Alfie’s is a particularly unusual syndrome, but the majority of children in similar situations have not been able to get access to medicines despite their now being legal.
