As for the coke users...I think that's a matter of circumstance. I don't think the vast majority of people will end up in as horrible of a situation with coke simply because it's way too damn fucking expensive. Also it's shitty and why anyone would want a coke high that lasts 45 minutes at most before you feel like shit over a somewhat less euphoric but more consistent speed high that lasts 4-5 hours before it makes you feel like shit is beyond me. Someone could offer me a drug that produces the greatest feeling in the world, but if it lasted for 10 seconds I wouldn't waste my money on it. That's what coke seems like to me, and it would be fine if you could buy a shitload and keep doing it to keep the high going but the price makes that a stupid decision unless you're loaded.
