I strongly disagree. Rarely do I see pot smokers whose lives are in order and pretty good. What I tend to see instead from pot smokers are frequent job changes, delinquent bills, evictions, criminal cases, and child support actions because they just can't seem to hold down a job.
In most cases, marijuana dealers end up providing lengthy lists of their customers. The first thing that happens when a drug dealer is arrested is that their phones are checked for any numbers in and out for calls and texts. The police then determine who those numbers belong to, and compile a nice list of the people who bought from that dealer. With rare exception, virtually every person on those lists have legal problems of their own that are in large part attributable to the marijuana use: divorces, child support actions, evictions, bill collections, criminal cases, etc . . . Yes, some may be appear to be living solid lives in nice neighborhoods, but dig a little deeper and you'll find plenty of legal problems in their lives. Again, often the wife/girlfriend will be working hard to keep things afloat, but the using husband/boyfriend is constantly coming up short. You see this sort of thing a few hundred times in the court system, and you can't help but note a trend.
You don't see the Disney vacation demographic on this list. Which ties in to the assertion that banning alcohol on property may end up resulting in the use of other drugs instead.
