Re: Yes, that is our 'logical' Catch 22
As to the proper approach to the problem of escalating *desire* for psychoactives: my preference is ever to seek root causes just as, My Other computer is your IIS Server suggests.
Some people just have some genetic affinity toward some types of drugs. I'm not saying it's predistined that they'll be addicted (gawl got too much of that predestination stuff in college) but some *will* be almost, not always, addicted.
Others will try, and discard, drugs like coke or marijuana.
Dammit, there's a much bigger problem to society posed by alcohol than marijuana, or cocaine, or damn near any other drug available (legally or illegally.)
