4-MTA is a derivative of amphetamine and has similar effects to ecstasy, being a potent serotonin releaser. Like ecstasy, 4-MTA is an empathogen, a class of psychoactive drug that generates a state of empathy and openness. It is often sold as ecstasy and comes in a pill form, coloured creamy white.
4-MTA is a Class A controlled drug. Penalties for possession are up to seven years in prison and/or an unlimited fine. Supply holds penalties of up to life in prison and/or an unlimited fine.
The drug has been associated with six deaths since it was first identified in Europe in 1997, and is thought to be responsible for at least 4 deaths in the UK, sometimes in conjunction with other drugs.
