During the course of a study on the effects of chronic, heavy marijuana
use, a placebo control subject reported dizziness and nausea, showed
tachycardia and conjunctivitis, and was found to have urinary cannabinoid
metabolites. Staff members observing the marijuana smokers also complained
of similar subjective symptoms. The detection of cannabinoids in the urine
of this nonsmoker documents the previously anecdotal concept of the
"contact high" and has implications for marijuana research and for
precautions that may be necessary should marijuana become legal.Abstract Teaser
