A National Assembly for Wales Health and Social Care Committee report has outlined a number of actions it says are needed to tackle the harms of using new psychoactive substances, or NPS.
The Committee found that NPS, or "legal highs" as they are sometimes called, are commonly marketed as safer and legal alternatives to illegal drugs.
Information provided to the inquiry showed that NPS can be as addictive and dangerous as illegal drugs, with some drug users noting that their side effects can be worse than heroin and cocaine.
60 deaths involving NPS were reported in England and Wales during 2013, 15 per cent higher than the previous year.
The health and social harms caused by NPS use are worrying, and we want to shine a light on the practical steps that need to be taken to allow people to make more informed decisions about using these substances.
We think the UK Government should move as quickly as possible to implement a ban the supply of NPS.
However it's clear from our inquiry that changing the law will not solve the problem altogether - improved substance misuse education in schools, increased public awareness, and better treatment services are just as important for ensuring that the number of NPS users in Wales is reduced.
Scientists in Cardiff responsible for testing legal highs are warning of the dangers that can be caused by unidentified substances.
One expert has told ITV News that she believes so-called legal highs are more dangerous than illegal drugs.
