Has anybody identified what it is that's put into marijuana to make it "medical" marijuana?

Menthol, maybe? I mean, hey, if the makers of Head & Shoulders can claim their shampoo is medicated due to menthol, why not the makers of marijuana?

The adjective "medical" applies not to the marijuana itself but to the purpose of its use. There probably is a better way of expressing that.
