The Mixmag Drug survey has returned after four years and thanks to the users of DSI and the readers of the magazine - this year's survey is the biggest ever.

The full results of the survey can be found in this month's Mixmag in shops now.

The big story from this year's survey is the emergence of Britain's favourite new drug - mephedrone, sold online as plant food.

For a sneak glimpse at the kind of results you'll find in the mag here are the facts and figures from the survey on mephedrone. You may be shocked by what you read.
