Yes, I know coke is only a mental addiciton but A LOT of people underestimate that power. When you do coke YOU WANT MORE. Not like "oh that was cool-let's do it again some time," its like you need more right there and then. It will run you into social, financial, and mental problems. Not to mention it is very easy to get caught up and die from an overdose. I've seen it happen to people I know. The main thing is that people underestimate its hold over you. You should go in kind of expecting to deal with addiction one way or another.

I don't know about you, but I would not feel great being high on a drug that could easily kill me. I like weed because it is relaxing, relatively safe, and good for my eye pressure that is abnormally high after a skiing accident.
