Are you telling me that Heroin and Cocaine aren't bad for you because they are both 'pain killers'? Look, I'm not that stupid. They both clog the arteries, cause severe brain damage, and whoever starts using either are really really really thick in the head. To do most of these drugs, takes a person who doesn't care about life, and someone who is very very disturbed and depressed. Marijuana isn't so extreme, but Heroine and Cocaine? It's a bit overboard.
No. I am not telling you that heroin and cocaine aren't bad for you because they are both pain killers. Cocaine isn't even a painkiller - it's a local anesthetic. I'm telling you that they
do have medical uses. Heroin can "clog your arteries" if you're using low purity heroin that has additives that get lodged in your arteries, but that's not the fault of the drug, that's the fault of the additives. Cocaine does not clog arteries. Heroin is not neurotoxic at all, so it causes no brain damage. Cocaine is DRI, or Dopamine Reuptake Inhibitor, which means that it only causes your naturally produced brain chemicals to stay around longer rather than pretending to be those brain chemicals. This causes it to be much less neurotoxic than drugs like methamphetamine -- which is also schedule 2.
I've done cocaine. I care a lot about life. I'm not depressed, I'm not disturbed. Your point that people who do drugs like that are disturbed, depressed, or suicidal is literally defeated by my existence.
