The use of buprenorphine and temazepam by drug injectors.

There has been concern over the growing misuse of buprenorphine and temazepam in Scotland. In interviews with 78 clients of Glasgow drug agencies during 1989-1990, it was found that buprenorphine and temazepam are now more widely and frequently misused than heroin or other opiates. Fifty-eight percent of buprenorphine users used six to seven days weekly. Fewer users of other drugs used as frequently. Heroin, other opiates and temazepam were associated with criminality. Buprenorphine, perhaps because it is relatively inexpensive, was not associated with criminality. Implications for drug policy and treatment are discussed.
