A 10-year review of drug seizures in Singapore.

The trend of illicit drug seizures and analysis in Singapore over a 10-year period from 1986 to 1995 was examined and reviewed. The main drugs were heroin, opium, cannabis, and illicit tablets containing benzodiazepines and amphetamines. The emergence of amphetamines in early 1996 was a major departure from the traditional drug abuse pattern in Singapore. Changes in the legal definitions of opium and cannabis were also reviewed.
