Re: Cannabis, cannabis everywhere: UK to review medical cannabis policy as Canada plans imminent legalisation for all uses

In this case a child could have come to serious harm due to misguided and outdated laws. In my own experience on placement I have been with parents who used CBD oil to control their terminally ill child’s pain and seizures with great success. This is where my interest and the awareness of the hypocrisy in drug regulation arose.

According to government statistics 24 people died directly from cannabis use in the UK in 2016, less than 1% of the 2593 UK deaths due to drug misuse.(1,2) 54% of those deaths were due to opiates.(2) Worldwide prescription opiate is spiralling out of control, especially in the US where 78 people a day are dying from opiate overdose either from their prescriptions or heroin addiction which stemmed from their opiate prescription.(3) Thankfully this trend isn’t evident yet in the UK but reported opiate addiction and deaths are on the rise.(4) However, if a patient comes into hospital with a traumatic fracture in severe pain would you give a second thought to giving them effective pain relief like morphine?

Benzodiazepines, amphetamines and neuropathic pain killers are all commonly used as drugs of abuse yet still prescribed so why are these therapies not grouped with other drugs of abuse and banned? They are obviously kept for their therapeutic value despite their other negative outcomes but then I see no difference between them and cannabis.

This is where the law has become archaic and oxymoronic as derivatives of cannabis have been shown to beneficial in not only epilepsy but multiple sclerosis, chronic pain and a range of mental health problems.(5-7) These have been shown in larger studies across Europe and North America where laws have been changed due in appreciation of the growing evidence base. This argument can then be extended to psychoactive substances such as MDMA, LSD and psilocybin where there use in anxiety, depression and PTSD has shown to be beneficial in patients where conventional therapies have failed them.(8,9) This is being explored more by Prof. Nutt and his team in Imperial College but only on very small scales due to government restrictions but worldwide there has been positive results in such studies.(10)

What I am not calling for is a complete disregard for the danger and abuse of these drugs; how to deal with illicit drug usage effectively is a completely different discussion which also needs to be had. I am calling to breakdown these outdated barriers which will allow pharmaceutical freedom to explore the functioning and ability of these drugs with evidence bases to discover and approve new therapies which have the potential to help hundreds of thousands of people. Hopefully these situations worldwide will spark a reform of this nature and not leave the UK behind in discovering the huge potential in such therapies.
