So in another thread about people's controversial beliefs I went on a little rant:
There are soooo many reasons drugs are illegal, but few have to do with what the fucking government tells us. More than anything, the drug war as we know it today is a way to crush political dissent. All those hippies doing acid/pot/mushrooms in the 60's were very "socially corrosive". Yeah, they were fucking with the system pretty bad, and you know the system doesn't like to be fucked with. More than just hippies, other minorities that used drugs could now be prosecuted(black militants, mexican immigrants, etc.) The "indirect harm" you refer to isn't so much that they really harm anyone so much as they harm the industrial system.
LSD has never been shown to do long term harm, even by the government's standards. Marijuana's harm is little, especially when compared to alcohol and tobacco products. Ecstasy, when not abused, has been shown to be very effective in improving people's relationships. It was originally used by marriage counselors. But all of these often cause people to question the value of their place in society, and the system can't operate that way.
Then you get to some of the harder drugs; meth, coke, and heroin. These are most certainly addictive and dangerous, but you can be prescribed perfectly legal drugs with more or less the same effects. For instance, Oxycodone is an opiate very similar to heroin. Morphine, used in hospitals, basically IS heroin. In fact, heroin turns into morphine once it metabolizes in your liver.
The drug war is no more than a way to further control the masses
MattShizzle pointed out that the religious idea "if it feels good, it's bad" probably comes into play.
I wanted to go into more detail about it, though. Is the idea of illegal drugs irrational?
