Medicinal Cannabis

Caroline Johnson Excerpts

Monday 18th June 2018 Commons Chamber

[Mr Hurd]

I thank the right hon. Lady for recognising the speed of movement by the Home Office this week in response to an emergency request from clinical leads at the Chelsea and Westminster Hospital. The Home Secretary overruled nothing in this process. We worked together very closely this week and responded, as I said, very decisively to an emergency request for a limited licence in a direct call from the senior clinician and the medical director at the Chelsea and Westminster.

I understand the right hon. Lady’s point about public sentiment on this. People are unsettled by what they have seen, and we totally understand that. What I regret is that she is trying to make a party political point. Of course, she was in power and Labour was in power for a long time, and they did the square root of very little in this context. The system we are now trying to work with is basically the rules we inherited from the last Labour Government.

I do not think anyone in politics is in a position to take a high moral stand on this issue. We need to give an undertaking that the policies and processes will be informed by the most up-to-date evidence, and we challenge ourselves harder to make sure these processes are more clinically led than they have been in the past.

[Dr Caroline Johnson (Sleaford and North Hykeham) (Con)]

I refer Members to my declaration of interest, as a consultant paediatrician. Some compounds within cannabis have anticonvulsive properties. Cannabidiol has been shown in animal studies to have an active anticonvulsant compound, but THC, the one that is illegal in certain concentrations, has been found to have both anticonvulsant and proconvulsant properties in animal studies, and there are concerns that it may also be responsible for causing significant psychological problems, such as psychosis, if used over a longer period. Epidiolex is a pharmaceutical grade, quality-assured product that contains cannabidiol but less than 0.1% THC, and it is both legal and used in clinical trials in this country, including with children. The oils available on the internet or at health food shops are not subject to that sort of scrutiny, do not have the same level of quality assurance and have variable levels of concentrations. Does my right hon. Friend agree that there is a huge difference between these two products—the quality-assured one and the not quality-assured one—and that we need to investigate the best possible scientific evidence on the usage and benefits of cannabis-based medicines, so that they can be used safely and properly to the best effect for our patients?

[Mr Hurd]

I defer to my hon. Friend’s medical knowledge, and her intervention just reinforces the point I am trying to make about the need for this process to be clinically led, as far as is possible. She is making the point about there being certain cannabis medicines and certain conditions, and the evidence is at best mixed on this. She makes the fundamental point about our responsibility, as regulators, being to make sure that people are accessing and using products that are tried and tested, and as safe as possible. Let us imagine the consequences of prescribing an unregulated medicine that goes wrong—imagine the scene in this House at that point. In our, understandably, emotional response to recent events, we must also make sure that we do policy right and get it right. That is why we require a little more time to come back to this House with more detailed plans.
