Not quite.
CBD's are the active ingredients in marijuana that gives it the anti-convulsant, anti-inflammatory and anti-psychotic properties, same goes for the cancer cell properties (disputable, as I cannot find a non-biased study). Active ingredient in Marinol is Delta 9- THC. THC is obviously the part that gets people high, but along with that it is an anti-emetic, but obviously lacks all the CBDs that make it more beneficial than Marinol. THC also has strong tendency to bring out psychotic properties, which CBDs help to counter act
So, going with that that mmj has quite a lot more benefits than just Marinol. However, I agree with several that the mmj system is abused. It needs to be tightened down, so that actual patients don't get labeled as abusers, causing possible future complications for them. Currently, many of the supposed "patients/ doctors" are not helping the cause in one slightest bit.
I think overall prohibition is a process that is occurring because of the overall ignorance surrounding the "tabooed," just as you mentioned with alcohol. People are afraid of the unknown.

Just what I was thinking. What is the issue with the FDA approved drug that does everything the natural does except het one high?
Again, not quite. As I stated before, THC is the psychoactive component of MMJ and the main ingredient of Marinol. It is currently in the process of being reformulated to likely reduce the side effects. Side effects of Marinol include:
mood changes;
dizziness, trouble concentrating;
feeling "high";
weakness, lack of coordination;
anxiety, confusion;
stomach pain, nausea, vomiting, diarrhea;
warmth or tingly feeling; or
sleep problems (insomnia).

You can refer to the link from NORML I posted that goes further in depth on the causation.
Edit: I apologize for the wall of text. It's late and I went a little over board, haha.
