I certainly don't mean to say that marijuana for medical purposes is bullshit, but the OP is correct that, in many cases, it is just a cover for someone who is not sick to get their hands on some legal weed. My point is that, even if that's the case, if it serves the purpose of demonstrating that marijuana is benign and even beneficial in some cases, then it's worth whatever 'dishonesty' he's taking issue with.
