I think the points of your argument should be comparing common anti-glaucoma, anti-nausea, and anti-pain meds to medical marijauna. The comparison should be based on cost, side effects and efficacy. In my brief look, the common side effects of these meds were much the same as marijauna.
Personally, I believe that marijauna is far less dangerous than many drugs already on the market. I also feel that the medical/pharamecuetical industry has little interest in investigating and investing in the medical aspects of marijauna because the raw form is readily available, if illegal, minimal processing is needed and administration of the drug is easy. It can even be argued that the whole plant provides more benefit than refined THC, because of other plant compounds.
The main benefit of fully legalized marijauna, in my opinion, would be the standardization of production, and dosage. No more strange chemicals sprayed on plants to help them grow.
As a side bar, I also advocate the decriminalization of marijauna. I think in terms of legalized drugs, it is far less dangerous than either cigarettes or alchohol. I think we waste far too much of the taxpayers money pursuing pot, and not enough fighting drunk driving.
