Respiratory effects of delta-9-tetrahydrocannabinol.
The respiratory effects of smoked marijuana and oral delta-9-tetrahydrocannabinol (delta9THC) have been studied in healthy males by assessing displacement of the respiratory response curve. Both cause slight respiratory depression, in some subjects it stimulates respiration. High doses of pentobarbital depress respiration but low doses apparently do not.
