• Of particular interest –• Heavy drinkers frequently drink to the point of

physical distress• Problem drinkers not only drink heavily, but also

experience trouble with authorities as a result – frequently, problem drinkers don’t label their own drinking pattern as problematic

• Context-dependent drinkers typically drink in social settings rather than at home by themselves or with family

• The single best expectancy predictor for heavy and context-dependent drinkers was social and physical pleasure, whereas the most powerful expectancy predictor for problematic drinkers was tension reduction

LSD

• Drug of choice in mid-1990’s• First ‘acid trip’ was taken in 1943 by

chemist Albert Hofmann, the creator of LSD:

Page 23: DRUGS. Drug Tolerance The diminishing effect with regular dose of the same dose. Psychological v. Physical…

“Last Friday, April 16, 1943, I was forced to stop my work in the laboratory in the middle of the afternoon and to go home, as I was seized by a particular restlessness associated with a sensation of mild dizziness. On arriving home, I lay down and sank into a kind of drunkenness which was not unpleasant and which was characterized by extreme activity of imagination. As I lay in a dazed condition with my eyes closed there surged upon me an uninterrupted stream of fantastic images of extraordinary plasticity and vividness and accompanied by an intense kaleidoscope-like play of colors.”
