About 6,000 Danes participated in a survey on drug use and quality of life. There was no difference in quality of life between cannabis users and those who had never used psychotropic drugs, while users of LSD had a 10% lower quality of life score. The groups with the lowest quality of life were users of heroin, morphine, methadone, and a mixture of alcohol and tranquilizers.
