The Many Uses of Drugs
Humans seem to have sought mind-altering experiences through drug consumption throughout history. Many drugs historically were only grown, produced, and consumed locally. After 1500, global trade in drugs began, leading to changes in consumption patterns. Drugs with local traditions of use are often embedded within cultural practices impeding abuse, while global trade goods can be more disruptive in societies.
