How recreational marijuana use may be both normal and pathological social behavior.

Durkheim treats deviance and crime as objective, measurable social facts. Deviance is both normal (ALL societies have patterns of deviance/crime) and pathological (patterns of deviance/crime are statistically infrequent compared to conforming behavior patterns). Explain how recreational marijuana use may be both normal and pathological social behavior. If most people have used marijuana ("normal"), how can it be defined as deviant ("pathological")?
