people who seek to legalize it are hoping that it will have the same effects as the end of Prohibition did. they are hoping that it will be an end to the violent gangs/cartels that are responsible for the violence involved in marketing this product. they will of course turn to other sources of income but i dont think anything causes as much violence as the drug trade.
it seems to make sense except for people being able to walk into a Walgreens and grab a box of dope.
i think it could have bad results, but its too hard to tell, purely speculative. you have to ask yourself, what's worse? a bunch of people running the streets high, legally? or the continuation of violence that we presently enjoy?
ps i equate marijuana to alchohol, actually it's not even as bad, and it should be legal to persons over 21.
