Horse tranquilizer "Special K" or ketamine has become one of the most popular illegal drugs in Britain, pushing aside cocaine, according to a crime survey. Ketamine—which can be swallowed, snorted, injected and smoked—can cause respiratory failure, but its low cost and reputation for being "safe" and non-addictive encourages users to try increasingly large doses, reports the Independent.
"Coke is more expensive and it generally makes everyone very loud and aggressive," said a regular ketamine user. " Ket makes you feel anesthetised to your worries. Everything is euphoric." The drug has been linked to 23 deaths in the UK since 1993.
