Some people feel that this reasoning should hold also for marijuana. A person who smokes at home is not doing injury. The marijuana user is indulging in a minor pleasure over which that government should have no jurisdiction. It is quite clear from survey data that most people do not become physically dependent on marijuana. The majority use it as others use alcohol - to relax occasionally and to indulge a festive mood.
Some people find any compulsive and unproductive behavior disgusting.
But that is not a reason for outlawing it. Consider eating, many people develop compulsive habits about food. They talk about it frequently. They spend many of their waking hours anticipating, planning, obtaining, and consuming food. This may be unattractive.
