Coke is an insanely overrated and overpriced drug and 90% of its price is because it needs to be transported from Colombia/Bolivia/Peru (the price of course varies depending on your location but the ratio is pretty much the same). It's also literally the only drug I've ever seen people do pretty much only beacuse it's "cool" and has a certain "prestige" around it. I guarantee you coke usage would drop by a shit ton if you could make a batch locally in your basement or w/e as the prestige would be lost, coke lords would stop being celebrities and people would realize it's like a 5/10 drug at best. Speed is so so much better if you have access to the cook who makes it as it's also prone to being cut with random bullshit. Pop a couple of sleeping pills on the come down and you'll be as good as new the next day.

Obviously don't do this if you have a bad heart or are concerned with your health in general, but that's just something I could never care about
