"Drug subcultures are groups of people united by a common understanding of the meaning and value (good or otherwise) of the incorporation into one's life of the drug in question. Such unity can take many forms, from friends who take the drug together, possibly obeying certain rules of etiquette, groups banding together to help each other obtain drugs and avoid arrest to full-scale political movements for the reform of drug laws. The sum of these parts can be considered an individual drug's "culture"."
