Driving along the Massachusetts Turnpike today, I noticed 2 very large, professionally designed (and presumably expensive) billboards advocating that the state legalize and tax marijuana. The name of the group sponsoring the advertisements is Change the Climate, and they are claiming that the initiative would produce something like $138 million annually for the state treasury. I'd be curious to know how that number was generated, given that the price of grass would likely plummet if it were legalized. In any case, the people behind this seem to be taking their cues from the gaming industry, which has very successfully exploited the fact that most state governments are deeply in debt and desperate for revenue from any source. It'll be interesting to see if the prospect of some fresh revenue motivates the social conservatives to reconsider their position on this issue. Here's a link-
