Medical marijauna question

The argument for permitting marijuana consumption was that it’s beneficial for certain things, such as:

Relief from nausea and increase of appetite;
Reduction of intarlobular (“within the eye”) pressure;
Reduction of muscle spasms;
Relief from chronic pain.

If that’s the case, why haven’t the pharmaceutical companies analyzed marijuana to determine the actual chemicals that provide these benefits? After all, no one chews willow leaves to get the salicin. Instead we consume acetylsalicylic acid, or aspirin.

I think they have. At least some of the studies I’ve heard about the particpants received pills, they didn’t smoke pot.

They have. It’s called Marinol, and contains THC (Tetra-Hydro-Cannabinol).

I should probably note that marijuana has other active ingredients besides THC. There are a bunch of other cannibinoids which aren’t included in marinol, and most patients prefer the real thing. Cost is also extremely prohibitive.

What’s wrong with Marinol
