what it comes down to is this: alcohol is unsafe, yes, caffeine is addictive, yes, Rx meds can be a source of addiction, yes. but here's the facts: no one is going to go for making alcohol illegal, again. while i believe in free choice and all that good stuff, there has to be some regulation. i see no benefit to making the possession of mj legal.
I see plenty of benefits:
1. We can use our limited law-enforcement resources to combat real crime.
2. We can save taxpayer money by not having to keep non-violent perpetrators of victimless, imaginary crimes locked up in our penal system.
3. We can focus our efforts on actually treating people with drug problems (although, in the case of MJ, very few users have a "problem"), rather than stygmitizing and criminalizing them.
4. We can eleminate the crime associated with trafficking illegal substances (we should have learned that lesson from prohibition).
5. We can regulate MJ so that the product people use is completely safe. (people are going to use pot whether it's illegal or not, so we might as well make sure that the pot they are using is safe.)
I believe, absolutely, that there should be strict laws against driving under the influence of any impairing substance. Because you are putting others at risk. But why should we have laws against doing things that don't put anyone else at risk?
There are lots more issues in criminalizing a substance than there are in regulating it. Imagine if we brought back prohibition. It would be a law enforcement nightmare. Criminalizing a substance as abundant as MJ is also a law enforcement nightmare. It is unnecessary.
Your argument is that we should stay with the status quo because it's the status quo. Well, the status quo is criminalizing millions of Americans unnecessarily, costing us a ton of money, expanding the power of the Federal government beyond its Constitutional limits, and causing the government to intrude into our lives in ways it has no business doing.
I don't like the status quo.
