while i do think that it's about time this ad came up (because, really, buying oil has a much greater chance of supporting terrorism than buying pot (even granted that the US produces a bunch of oil, and gets a bunch from Canada)), i think it's funny that it misses a key point.
someone driving a geo metro as a regional sales guy would buy more gas than a soccer mom driving her SUV to the store and back.
you might even be able to suggest that you're supporting terrorism by buying any products at stores. lots are shipped by truck, many shipped by oil-consuming boats.
