It should be easy for your wife to get a medical marijuana card from her doctor in CA, and there are also 2 forms of an Rx pill of THC named “Marinol” & “Cesamet”...why the need for statewide recreational legalization? We don’t need more “drunks” on the road, and further societal degradation due to chronic overuse.

Marinol sucks.
It is not THC that provides the pain relief in most cases, but the myriad of other components, mainly terpenes.
Thus, there is no reason to take Marinol.
