Why don't we just focus on marijuana, since the general international consensus is that "weed" has no negative effects on your health. It's probably one of the most harmless drugs out there, unless you're one of the roughly 15% of overweight people who gain weight from genetic defects and are suspectible to eating binges. In fact, I'm sure many of you would be fascinated to learn that marijuana was made illegal in the United States only to discriminate against Hispanics, who had come to this country and were (at the time) the largest group using the drug. So, happy with your discriminatory drug legislation?
Please drop the "drugs are bad, mmk?" mindset that's been brainwashed into you from years of pressure from society, DARE, and who knows what else. Not all drugs are bad, and sometimes the government does stupid things for no logical reason, and maybe, just maybe, when faced with a good argument, one should consider revising his/her viewpoint instead of ignoring the other person or simply spouting non-sequitur or repetitious statements over and over until a thread is locked.
Oh, and though I find this hardly relevant - because the arguments should stand on their own - I don't use drugs, unless you count Tylenol and Dynotap (or however it's spelled).
