A NEW LAW to crackdown on legal highs comes in this month.

The Psychoactive Substances Act 2016 has been strongly campaiged for by Barnsley MP Dan Jarvis after a number of complaints from constituents about people vomiting and passing out in the street.

The law aims to ban any substance intended for human consumption that is capable of producing a psychoactive effect.

The act is set to come into force on May 26.
