The object of this study was to establish possible influences of long-term cannabis usage on plasma testosterone levels. The plasma testosterone levels of 66 male Pakistani who for years had smoked cannabis daily or drank cannabis regularly where measured after chronic and acute intake of the drug and compared with a material of 41 normal controls, i.e. persons who did not use cannabis. An evaluation of the results showed that there were no significant differences between the two groups. No influence of long-term cannabis usage on plasma testosterone levels was found. Furthermore we wished to find out wether long-term heroin abuse showed an effect on plasma testosterone levels. The concentrations of testosterone in the plasma of 102 heroin addicts assigned to a Methadone Program were measured and compared with the values of 29 male healthy students as controls. Plasma testosterone levels were found to be significantly decreased in heroin addicts as compared to controls.
