First, alcohol is one thing. Marijuana is one thing. Even some soothing pills are another, but Heroine and crack?
"Hey, I'll take an E now and work tomorrow, I'll be normal!" ... have you ever tried these drugs? You can't compare alcohol with Excstasy, they're nothing alike. Being high/drunk isn't that simple, Exctasy and LSD makes you "weird" in the head for a few days...and most likely do permanent damage. If not physically, on a mental level. I would never hire someone that told me "I take the occational partypill
hehehe".
As for getting high on THC, I used to smoke alot, on a daily basis...heck, I had an addiction. *hears people go "BUT YOU CANT GET HOOKED ON IT!"* ...mhm.
If you smoke daily (or at least twice a week) you're mind gets all mushy. Not in a week, but try a couple of months of daily puffin'. People get "slow".
Now of course, daily drinking isn't alot better, but as long as you're not hung over, you're the same person you were before you had that sixpack.
About legalization, I don't know. It's a tricky one, but I'd never agree with legalizing hard drugs. Just to at least protect the kids that don't get the stuff because they're not selling them in a store across the street of the school.
