Clinical effects of methamphetamine vapor inhalation.

Author information

Department of Psychiatry, School of Medicine, University of North Carolina, Chapel Hill.


Despite the increasing popularity of crystalline methamphetamine ("ice") vapor inhalation, no investigations have reported drug plasma concentrations and effects. Under controlled laboratory conditions, six subjects were studied. Plasma concentrations of methamphetamine were determined, and subjective and cardiovascular effects were measured. Methamphetamine appeared in plasma rapidly, increased slowly over the next four hours and then progressively declined. The dose of methamphetamine administered produced modest ratings of subjective drug effects, and moderate changes in cardiovascular parameters. Both subjective and cardiovascular effects rapidly decreased despite the presence of sustained concentrations of methamphetamine in plasma.
