Not only that, but there is a substantial body within countries like the United States who benefit a lot from it being legal. For instance, the for profit prisons incarcerate non-violent drug offenders. Also, law enforcement relies heavily on policies such as seizures as a source of funding. These types of institutions also have a lot to lose when it comes to drug legalization...
Possibly, though I imagine that tobacco companies would probably find away to be the biggest beneficiaries if it suddenly became legal.
By a long shot. I'd say they could start producing joints with exactly the same production lines they already have. You'd see tobacco+marijuana cigarettes too - a highly marketable combination of high and addiction.

Damn, right there's almost good enough reason to oppose legalization.
