Ben Bradley, Tory MP for Mansfield, said cannabis-based drugs, such as Mamba and Spice have been linked to violent behaviour and serious mental health problems and should never be legal.
He is demanding that the synthetic cannabinoids – currently a Class B drug – be reclassified to the most serious Class A category along with heroin and crack cocaine. He will call for a law change during a debate in the Commons later this week.
It comes after Home Secretary Sajid Javid last week allowed cannabis to be used for medicinal purposes. However the decision has added to the pressure for the liberalisation of cannabis-based drugs.
Mr Bradley said: “While there is a great deal of sense in the medicinal use of cannabis in some cases, comparisons with synthetic cannabinoids are inaccurate.
“The impact is far more extreme and we must take immense care when considering liberalising laws on cannabis, that the impact of incredibly dangerous drugs like Mamba and Spice are not trivialised.”
He has been raising concerns over the use of the drugs, which can cost as little as £5, in his Nottinghamshire constituency.
Mr Bradley said: “Many towns are facing challenges with psychoactive substances that are increasingly visible; users passed out in the street, stealing and fighting over drugs, and causing immense anxiety to local people, and businesses which see footfall plummet as a result.”
He believes that the drugs’ seriousness is not reflected in law, and said: “Strangely, though they are Class B.
“Anecdotally, I’ve been told it’s far more addictive than heroin or cocaine.
“The physical and psychological impact is more comparable with Class A drugs than it is with cannabis, and the impact on communities is worse than all of these.
Mr Bradley added: “The police must have the powers to act to cut off supply, to bring down manufacturers, and to protect people from users in our streets.”
