Such an action would eliminate the untaxed cannabis economy overnight. People will either buy commercial stuff, grow their own, or more likely a mixture of the two. Any money they previously spent on marijuana will be largely redirected into the economy by way of spending on commercially-grown stuff (those who don't grow), or spending on other stuff (for those who do, and have more money to spend as a result).
End result: More of everything is sold, more jobs are created and governments gain more tax revenue.
