Marijuana & Respiratory Function During Exercise Acute effect: any smoke can interfere with oxygen binding to red blood cells Acute: marijuana can disrupt coordinaIon, balance, reacIon Ime Acute: increase heart rate and blood pressure Acute: stored THC in fat could be released into bloodstream during exercise Chronic: depends on how frequently one smokes, type of exercise LSD • LSD Albert Hoffman: “Last Friday, April 16,1943, I was forced to interrupt my work in the laboratory in the middle of the afternoon and proceed home, being affected by a remarkable restlessness, combined with a slight dizziness. At home I lay down and sank into a not unpleasant intoxicated-like condition, characterized by an extremely stimulated imagination. In a dreamlike state, with eyes closed (I found the daylight to be unpleasantly glaring), I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colors.
