MSJ Guide (Diazepam)


MSJ (Diazepam) Information & Advice


September 2011

Over the past couple of years, the misuse of benzodiazepines (benzos/minor tranquillisers/sleeping tablets) has been steadily growing across the country. This is a very serious concern.

Known as MSJs or blues, they are valium that can be obtained via the internet and distributed locally. The reason for their current popularity may have something to do with the recent heroin and ketamine droughts and the poor quality of other drugs, but probably has more to do with availability.

Our sources tell us that heroin and crack users are taking benzos orally (not much injecting – yet!) but, more surprisingly, they are becoming popular amongst a whole new group - alcohol users are now supplementing booze with a fistful of blues. Although benzos have been around for decades, this new generation of users may not be fully aware of the very real problems that these drugs can bring.

So we’ve decided to put together some information and harm reduction advice to warn of the risks involved.
