Government crackdown on 'legal highs'

A blanket ban on so-called legal highs is proposed in a new bill that is being published.

The government wants to stop the sale of all mind-altering substances apart from alcohol, tobacco and caffeine.

The Psychoactive Substances Bill would mean anyone trading products intended for human consumption which have a "psychoactive effect" could face a maximum seven-year prison sentence.
