I know you weren't saying my views are wrong. :)
Everything comes with issues, but that's life. There are a lot of things that are legal that will harm us, like fast food, but most of us agree that they shouldn't be illegal and it's up to the individual to make the decision whether to ingest said food or not. Tylenol can cause acute liver failure in healthy individuals, but that is a risk the user takes. Ibuprofen can cause bleeding ulcers and you can hemmorage to death from it! I had a prescription that had the side effect of seizures listed (WTF?!) If a loved one were to ask me whether or not they should try meth, I'd say "hell no," but it's their life.
Unfortunately we live in a post Reefer Madness time and we are trying to undo the damage. Cocaine used to be in cola! and heroin used to be given as medication. Back then people didn't have a problem with that. Also, there was a time when birth control was illegal. Most of us agree that it is nobody's business except for the woman taking it. All growing up I believed what we were taught in school based on the anti drug campaigns, etc. I was born right around the tiome the war on drugs really kicked off, so I was taught IN SCHOOL that drugs (incuding mj are terrrible and ruin society.) Now that I am an adult who has 1) observed the facts, 2) seen how rediculous reefer madness is, 3) know why mj and hemp were really made illegal, and 4) done a lot of research because that's how I am, I've come to realize that I was brainwashed as a child per the war on drugs agenda. In reality, some drugs, like mj, ecstacy, mushrooms, etc are not that bad for you. They can cause problems, but they are not nearly as bad as some prescription drugs. Psilocybin (the active ingredient in magic mushrooms) is actually being studied and found to have medicinal uses. I believe ecstacy is also being studied and found to have some medicinal benefit as well, but I may be remembering incorretly.
I'm not trying to convince anyone of anything, I'm just stating what I have learned and how they have affected my views.
