Probably, aspirin isn't the catch all wonder drug it was originally thought to be, and in some cases is dangerous. Used to be aspirin was prescribed for everything, from an infected hang nail to flu symptoms.
I'm sure there are plenty of "qualified" folks out there who would prescribe pot the same way. "Hey dude, check it out. Got a hang nail and Doctor Bob gave me this righteous pot."
"Far out dude! He gave me the same thing for SARS last week!"
