“A ban on several drugs known as ‘legal highs’ has come into force. The substances, including GBL and BZP, become Class C drugs, with a possible two-year jail sentence for possession. Ministers moved to classify them after a recommendation from the Advisory Council on the Misuse of Drugs and fears they are a threat to user health. GBL was linked to the death of medical student Hester Stewart, 21, in Brighton last April. Her mother, Maryon, campaigned nationally for the ban. So-called legal highs are typically man-made chemical substances designed to act like banned drugs.” (12/22/09)
