Note that the article says they want to legalize the controlled sale by licensed shops. This suggests home-growing will likely continue being illegal.

While the legalization is likely a good thing, the article is a bit too trusting when it comes to the supposed motivation not being economical or fiscal. The goal is likely to be able to tax it like cigarettes and wine, and to make it easier for existing cannabis companies (which are mostly already established tobacco companies) to enter the market without fearing price dilution from private growers.
