Eh, I would say it's closer to saying legalizing weed is one step closer to legalizing heroin. Probably yes, perhaps not, but in what capacity? The fear monger says heroin will be available for sale at the corner store and frequently used recreationally in the same capacity as weed. Regardless the legalization of weed has opened up the discussion legalization of other illegal drugs, but there is discussion as to the role of legalization that is different to what happened with weed
