Despite weed and bath salts dominating the media coverage of drugs in 2013, it was a very different addictive substance that proved the most popular last year. The 2014 Global Drug Survey (GDS) indicates that alcohol was the drug used most last year, ahead of tobacco and cannabis. Alcohol was also the most common drug to send people to the emergency room, and the vice that users' friends and relatives worried most about. The GDS is the world's biggest annual drug survey, polling people's use of addictive substances.
