Just like back in the days of prohibition it's costing the Government too much to enforce the laws against illegal drugs and such. I think they should all be legalized so everyone who wants to use them can and at will without the stigma of being a criminal attached to them.
That said I do wish those who wanted to use drugs could but only in the center of the USA like say Nebraska, give 'em Nebraska, let them stay there and do what they want but leave us "normal" people alone.
If only I were Queen........
