Notes for this study:
Acute inhalation of two doses of cannabis (1.75% THC cigarette or 3.55%) appeared to increase global cerebral blood flow in both hemispheres when tested after 30-60 minutes, but not after 120 minutes. These changes were associated with an increase in tension/anger, intoxication, but no significant differences in blood pressure noted.

Placebo cigarettes were used in this study, and while the study was acute in nature it was conducted in persons with a history of cannabis usage who did not consume any two weeks prior to the study.
