Ah. Well, Marijuana should not be legalized at all. No matter what potheads say, legalist activists say, or Barney on speed might say I will not change my mind on that. Cannabis and hash is not healthy, least of all in a smoked variant, because it contains most of the bad stuff tobacco contains, and is much more damaging to airways, lungs and brain. Well, not so much brain, but it seriously inhibits short term memory and coordination. One joint is as bad as a small pack of cigarettes in terms of airways damage, one joint contains five to ten times as much tar as a cigarette, and furthermore sideffects can be paranoia, apathy, depression, and even schizophrenia. The list is a lot longer of course, but well... Whoever wants to fight for the legalization of this can take their joints and stuff them up a certain place. Yes, it is true that there are no documented cases of THC related deaths, but don't forget that pot when smoked gives off the same physiological damages as cigarettes do. If you die from any normal smoking related death, the culprit may just as well be marijuana or hashis as the symptoms are the same. They affect your body (in terms of cancer and such) the same way. Besides, most who smoke cannabis also smoke tobacco, so the deaths are attributed to tobacco - and not cannabis.
If you want to legalize it as a medication, be my guest. I want that too. As pills mind you. If you want to legalize it as a recreational drug.... No way am I going to support that. It will only harm our society to have more drug users around. Even users of light drugs such as cannabis.
As for the FDA.... Well, they do seem to.... Well, do an extremely bad job at what they are supposed to do. I mean, the food people legally sells in the USA would get you in trouble if you sold it for pets or livestock here in Norway. The way drugs are priced and handled in the USA is also highly beneficial for the producers, and extremely unfortunate for the people who must use them.
That being said, there is nothing which speaks for legalization of cannabis except a few poorly thought through claims that it will end cannabis related crimes, well duh. If you legalized murder you would have no murderers in jail. It does not eliminate any problems though, it only serves to increase them. Amphetamine is legal for medicinal use, and so should THC be. But as recreational drugs both should be outlawed.
