> I'm not sure where they came up with the "marijuana causes drinking" scenario, though. The link between alcohol and marijuana use is very complicated, to say the least. For example, a decrease in price of marijuana leads to (obviously) more marijuana use, but (less obviously) fewer DUI-related deaths. It has also been found to be more directly linked to lower alcohol consumption. Thus, you'd want to call them substitutes (with the economic meaning of the term). However, it has also been found that banning alcohol (on a school campus, specifically) led to a decrease in marijuana use, showing that they also can behave as complements to each other. Its all very complicated and its hard to be sure how these interactions will go, although most evidence does seem to point in the direction of lower alcohol consumption.
