People in all cultures across time have used psychoactive substances
as part of their social and religious rituals.
In North America, people use a variety of substances to commune with others, celebrate, relax, recreate and de-stress. Consuming alcohol is a legal and socially acceptable way to socialize and unwind. Moderate alcohol use is generally not a problem; it becomes a problem when it results in a pattern of impaired control of substance use, social impairment and risky use.
