as far as Im concerned, what adults ingest in their own homes is none of the governments business, on a state or fed level
No one has ever considered you an authority on anything (I'd bet). Illicit drug use, or the misuse of drugs prescribed by patients and doctors is a societal problem, and one which has continued to be problematic for decades. The War on Drugs, and Just say NO have been total failures and it's time to think outside the box.
Save the money: regulate drugs and put the black market out of business. It will be less expensive, more humane and less problematic if we regulate the production and dispersion of drugs under government control.
That said, deregulation is not the panacea, for more needs to be done to prevent corruption (remember SOMA, for example) and the regulators will need to be regulated.
