Will it just create another blackmarket with another organized crime taking control? I'm not sure about legalized states in America but in Canada, from what I hear all the dispensaries in Vancouver and beyond source it from the black market.

Also unlikely that the overwhelming demand will be filled by the legal producers after July 1st, it seems like such a long road to true legalization.

Tobacco is legal and yet allegedly about 1/3rd of tobacco sold in the Ontario area are also smuggled from the US.
