While one of your answer givers states it causes psychosis in people under 26, it still causes less problems than alcohol and tobacco. the jury is also out on the psychosis debate as it appears people suffering psychosis are drawn to the drug as a means of coping, not the other way around.
The real reason is more complex than you might think. Ignore anyone who says the government can't tax it - they can. Ignore anyone who says drug companies can't patent by-products of cannabis - they can and already do. The no. 1 reason in the USA was Richard Nixon believing that cannabis was the cause of social unrest during the late 60's/early 70's. He was given a report when they were classifying drugs showing that cannabis should be legal, however he threw it in the bin without even reading it. The real reason for the social unrest was Nixon himself and a war in Vietnam that nobody wanted. Nixon was NEVER going to admit that, not even to himself.
From there Nixon created the DEA and the US Gov't has since poured billions and billions of dollars into fighting a futile war on drugs. For the government to change their mind would show they were wrong. further, the propaganda spread through the 1920's and again the 1960's was believed by so many.
In states of the US where free thinking is encouraged (ie California) the citizens realized they were being lied to and there was a huge groundswell of support for medicinal use. In terms of full legalization the good people of Cali aren't quite there yet (although 49% of people are).
While the groundswell for legalization occurs, the biggest revolt against legalizing cannabis in California came from Humboldt County - NorCal's premium cannabis grow area. The reasons for this though are purely economical. When cannabis is eventually legalized the good folks in Humboldt will need to grow a lot more to make the same money, as prices will inevitably fall.
So you have the government not wanting to admit they were wrong, then have potential cases of people suing them for their incarceration over cannabis charges combined with old, misleading propaganda all capped off with drug dealers wanting to keep their profit margin high.
There are more reasons to go along with this, but we oly have so much time to spend here and I think I covered the main ones.
Research, research, research. Originally I was against legalization, but now I'm all for it.
