Good luck with that. Busting drug offenders is big business when you consider that even minor offenders bring usually more than $1,000 into the system each, and much of that money goes into private hands (rehabilitation services, etc., etc.). Even if it were discovered that cocaine could cure cancer, it would never be legalized.
To address your question about the safety of cocaine as opposed to alcohol, IMO it's probably considerably SAFER in many ways, but this would be to assume that you had pure cocaine. Almost all cocaine is produced with dubious chemicals, under unregulated circumstances. And beyond that, each time it passes through another person's hands, it's usually "cut" to make it weaker and increase profits. You don't even want to know what's in there sometimes, from household bleach to God knows what else.
Cocaine is certainly addictive and dangerous, will cause erratic and drug-seeking behavior; the only reason I say it MIGHT be SLIGHTLY safer than alcohol from a physiological standpoint is that it shouldn't toxify organs like the liver as badly or quickly as alcohol can. Anyhow... Don't hold your breath waiting for any substance, even marijuana, to become legal and readily available anytime soon, at least not OTC.View Thread
There are people who drink more than that every single day. That's not to say over many years, that it won't do damage, but people drink too much all the time, and doing it once is not going to cause any damage whatsoever, especially at your age.
It is wise, however, to not make a pattern of doing this as studies show that people who drink regularly before they are 21 are much more likely to become alcoholics as adults.
