The majority of Americans (54 percent according to a recent Pew Research Center Study) support the legalization of marijuana.

We wanted to know (obtaining a medical marijuana card aside), how difficult is it to find marijuana in the 20 states that sell it?

It looks like a piece of cake in California, where there are more than 2,000 dispensaries. But the establishments aren’t so common in all states where medical marijuana is legal. Check out the top 10 states by number of dispensaries per square foot in the graph below.

    Wouldn’t per head of population make more sense? I suspect the queues are longer in Providence than enthusiasts would like.

    The best way to determine good alcohol is to drink a little more than you should. If you don’t get a headache from over drinking it is good to drink again.
