It is pretty ridiculous that you can take a shot of testosterone, which directly increases your ability to inflict damage, but you can't smoke a doctor prescribed joint. Even if you don't have a doctor's note for TRT, the penalty is about the same as it is for weed legally (someone correct me if I'm wrong, but I think Riddle and Diaz both have med marijuana cards).
Also, on a side note, I think he's right about major companies being the only real road block stopping weed from being as legal as alcohol. The world would be a much better place though if everyone gave up the booze and started blazing. I smoke weed every day though, so nobody really cares what I think.
