Myositis Pain and Marijuana Use

Question

I have Polymyositis. My cpk levels are always 2500-3000. I smoke marijuana and I was wondering if it could make my levels so high?

Answer

The muscles of polymyositis patients tend to be very sensitive to the toxic effects of illicit substances.  Thus, it is probably that marijuana use could contribute to your persistently elevated muscle enzyme levels.
