Government VS Marijuana ?

It's kind of like how every argument against gay marriage has been argued down, yet it's still illegal. It's mostly people who live by ideology and wish to keep it illegal, for moral or other reasons. I say legalize it...smaller government, more freedom, more sales tax for the state, and less money spent into pursuing non-violent pot smokers and afterwards locking them up with violent criminals. Save room for the violent criminals in prison, leave harmless pot smokers alone. I am for illegalizing driving under the influence of marijuana (obviously) and incriminating people who do so, but that's for endangering others, not for the pot smoking itself.
