Education would allow users rational choice on 'legal highs'

We should be honest and allow people access to "safe intoxicants" like cannabis, former government drugs adviser Professor David Nutt tells Channel 4 News.

The government has announced that it is to review the regulations that cover so-called "legal highs" - synthetic drugs that can be bought online and over the counter.

But campaigners say banning such drugs is not the way forward.

Maryon Stewart's daughter, who was a medical student, died after taking a legal high called GBL as well as drinking alcohol. Ms Stewart told Channel 4 News that at the time of her death European nightclubs were running poster campaings warning that GBL plus alcohol equals death, and if her daughter had known the risk she would never have mixed the two: "she was unsuspecting, and so was her friend who gave it to her."
