Following a series of positive clinical trials, the UK’s debate over integrating psychedelic-assisted therapy into the National Health Service has intensified. While patients regularly report life-changing breakthroughs, national experts remain divided. The main sticking points are the speed of the rollout and the current legal restrictions on the substances involved.
In the UK, all classic psychedelics are Schedule 1 drugs, meaning they are considered to have no medical value. This means obtaining a licence to study them, let alone administer them widely, is extremely difficult. Advocates like Professor David Nutt argue that:
There are so many people suffering unnecessarily…and some of them are dying, because of the unreasonable barriers to research and treatment that we face in this country. It is, in my view, a moral failing.
The safety profile of psychedelics is a central bone of contention in the British medical community as well. Data from the Challenging Psychedelic Experiences Project indicates that over 50% of regular users have experienced a “challenging trip,” with nearly 9% reporting impairment lasting more than a day. However, scientists like Nutt counter:
These medicines are proven to be safe and effective…it is vital they are made available through the NHS to all who need them, not limited to the private sector, as happened with medical cannabis.
Despite the controversy and concerns, 2026 is set to be a pivotal year. Results from Compass Pathways phase 3 study are due later in the year. The UK government has also begun work on easing licensing requirements for university and NHS research. If these large-scale trials confirm psychedelics’ safety and effectiveness in a therapeutic context, then, advocates argue, there is no excuse not to make them available on the NHS.
For now, though, ketamine remains the only psychedelic-adjacent substance permitted for medical use in the UK.
