Medical marijuana programs are not run by the cartels, so why would regulating marijuana like alcohol be any different?
Answer me this. Do you support the authority of states under the Tenth Amendment to conduct medical marijuana programs without fedgov interference, or do you support fedgov's use of the expansive Commerce Clause to shut them down?
Medical marijuana is not generalized legal marijuana. When pot is legal there won’t be a need for medical prescriptions. So your remark is pointless and misguided.
Regulating alcohol entails licensing and distribution rights. Such operations are populated by organized crime families who support prominent politicians:

It will be different for marijuana and narcotics, the Columbian Cartels are terrorists, they will control all marijuana licenses and distribution. They control more than half of Mexico now and they will control large parts of the USA once the law lets them in. They will place prominent politicians on their payroll who on the surface will be like Romney and tell you whatever you want to hear but at core won’t care a twit about your silly conservatism. All they will care about is protecting their crime rackets and their distribution channels, legal or not.
