BACKGROUND: Talcosis, a granulomatous inflammation of the lungs caused by inhalation of talcum dust, is a rare form of pneumoconiosis. Besides inhalative occupational exposure, intravenous abuse of adulterated drugs is a major cause for this condition. Minerals such as talcum (magnesium silicate) and sand (predominant silicon dioxide) are used to increase both volume and weight of illicit substances. In intravenous heroin-abuse, talcosis is a well-known complication. Here we describe a case of talcosis caused by inhalative abuse of adulterated marijuana...

DESIGN AND PARTICIPANTS: Data from the Marijuana Treatment Project's screening assessment were used to examine correlates of pre-treatment drop-out. Information from all eligible study participants (n = 813) (i.e. those who were interested in receiving treatment for their marijuana dependence and were determined to be eligible for the randomized treatment efficacy trial) was used to examine differences between the 450 participants who initiated treatment (by enrolling in the trial) and the 363 individuals who declined enrollment...

One hundred drug abusers, free of clinical signs or symptoms of disease, were examined by electrodiagnostic techniques. Sensory conduction of median, ulnar and sural nerves was evaluated in terms of latency, velocity and amplitude of evoked potential. Motor nerve latencies and conduction velocities of median, ulnar and personeal nerves were determined. Definite changes in the evoked sensory potentials of median and sural nerves of subjects using heroin or LSD were demonstrated. The sensory amplitude changes were suggestive of axonal degreneration because of normal duration...
