-Butyrolactone (GBL)

GBL, or Gamma-Butyrolactone, is known as “coma in a bottle”.

It is used as paint stripper and was banned for consumption in 2009.

GBL is odourless and tasteless when diluted and is sold online for as little as 50p a shot.

The effect is similar to ecstasy but there is a high risk of overdosing.

Some users say it feels as if their muscles are being torn apart.

Medics say it kills six a year, damages organs and leads to psychosis.

It is related to banned date rape drug GHB.
