I took the drug and alcohol abuse test today. Mine only had 103 questions. I reviewed the link with the quizzes you posted as well as a study guide from Passyourclass.com. Between those and IC, which was great, i think i smoked it. There were only a few questions a had absolutely no clue on.
Several questions on narcotics, hallucinogens, and barbiturates. Alcohol, and effects of abuse. The 5 schedules and what they are based on. Thats about all I remember.
