But, I'm of the opinion that sin taxes are anti-American. And while taxing marijuana isn't as bad as taxing cigarettes, morally speaking (since pot isn't addictive), I still don't like the idea of taxing subsets of this country.

You'll get tax money off the people making money on producing and selling it. That's already a step in the right direction. 'Double taxing' select portions of the population is flat out wrong.
