Epidemiological descriptions of drug abuse in the US in the last three decades have generally not included data on the patterns and trends in the incidence of illicit drug use (i.e. new users). In this paper, estimates of illicit drug use incidence are presented, based on retrospective data from the National Household Survey on Drug Abuse. Incidence of marijuana use began increasing in the 1960s and reached a peak in 1973, after which a continuing decline was seen. Cocaine use incidence began to increase in the late 1960s and reached a peak in 1982, then declined.

Methods are described for assessment of the abuse liability of opioids and analgesics. The methods developed by the USPHS Addiction Research Center for assessment of opioid abuse liability have served as the prototype for most currently used abuse liability assessment approaches. ⋯ Specific methods, including the Addiction Research Inventory, adjective- and visual analog rating scales, are described, as are methodological developments that have been introduced to improve the sensitivity of the procedures and to adapt them to modern circumstances. It is concluded that the profile-of-effects methodology has proven extremely useful and should remain a basic element in abuse liability assessments.

Information was abstracted from the hospital notes of 144 doctors who had received treatment for drug and alcohol dependency. These problems affect those in every specialty, and at all degrees of seniority. Over half came into treatment following medical referral. ⋯ Of the 83 subjects who were misusing drugs, only four had ever used blackmarket supplies. Psychotropic agents are readily available to doctors, but the consequences of this are not addressed. Those who develop dependency suffer a delay of years before reaching help.
