The purpose of NDIE is to coordinate the collection, collation, analysis, and dissemination of foreign and domestic narcotics intelligence for policymakers and agencies and individuals working in the field of drug enforcement. Trends in the drug market for 1983 indicate that the single most significant change took place in the heroin market due to the resurgence of Southeast Asia's Golden Triangle as the principal source of heroin entering Canada's illicit market. This source accounted for 68 percent of the market as compared with only 21 percent in 1982. In addition, cocaine availability continued to escalate in Canada in 1983, reaching the major metropolitan centers as well as penetrating smaller communities and remote areas as had been predicted in NDIE 1982. The major cocaine producing source is Columbia, dominating the trafficking of cocaine to Canada with an estimated 64 percent of the illicit market. It has been found that the majority of the chemical drugs on Canada's illicit market find their source in domestic clandestine laboratories, illicitly manufactured and diverted drugs from foreign sources, and diversions of drugs legally manufactured in Canada. It was also found that marijuana, hashish, and liquid hashish continued to be the most widely available and used illicit drugs in Canada in 1983. There was a 25-percent increase in the total amount of cannabis derivatives seized by the RCMP in 1983 over 1982. Measures suggested by the RCMP antidrug program as well as international and national control measures are discussed. Tabular data are presented.
