Treatment Clients in Sweden by Substance Used, 2012
"The distribution of drugs changed somewhat in 2008, with cannabis becoming more frequent than heroin. This trend has continued in data for the clients reported from treatment units in 2009: cannabis is now much more frequent than heroin.
"Amphetamine is still the most commonly used drug (29%) among the reported drug clients in treatment outside prisons, followed by cannabis (23%), heroin (17%), other opioids – analgesics and buprenorphine (11%) and benzodiazepines (11%).
"Cocaine use is still rare as a drug being the reason for seeking treatment (1%), and crack cocaine is almost non-existent in this population, as are methadone, ecstasy and hallucinogens."
