If there really is such a thing as an addictive personality then I qualify. Born in Germany and raised on beer for lunch and wine for dinner. In my mid-twenties I was an alcoholic like my dad and his dad before him.
In between there were amphetamines, hash, opium, LSD, pot, and of course lots and lots of booze. In my experience alcohol was the gateway drug for everything that came after due to my desire to escape from reality and an inability to cope with the stresses of my life. At 29, after two divorces and being in and out of hospitals and jails, I kicked everything.
The thing is, not everyone has an addictive personality. Most people are moderate in what they consume and smoke. Some can smoke a little bit of pot or drink a couple of glasses of wine at night and function just fine. Lumping everyone into the same group for fear that they will ruin their lives is nonsensical.
The positives of pot:
1. It's a pain reliever
2. I've seen plenty of fights break out amongst drinkers but never among pot smokers, unless you get in the way of their munchies.
The cons of pot:
1. My son had his car totaled by two girls smoking pot. Do we need more inebriated, distracted people driving?
2. Health problems due to ingesting smoke.
There are a lot more pros and cons but these are what first came to mind. In my 14 years working in the Federal prison system I have met many fine, young men who were incarcerated for pot offenses, some got outrageous sentences. In a society inundated with booze and prescription pills, this is hypocritical.
Still, I don't want to see one more person injured or killed while out driving by someone who got behind the wheel while stoned. Obviously I have mixed feelings about this topic.
Btw you all have done a fine job in this thread. As long as it doesn't get snarky and personal it should continue on.
