well to a certain degree. Here in the uk, we have GW pharmaceuticals. However if they legalised it, it makes it hard for the goverment to tax it, therefore all the people who grow there own, it would make that hard to tax and would cost the goverment a lot of money to try and control. However if the goverment could issue licenses to grow up to 5-10 plants each and you had to may £500 annual fee, then I think that would be fair, as it would give us the growers, to grow our own and not worry about getting raided, whilst the goverment get £500 of each person who wants to grow.
It also had the advantages of stopping organised crime, drug smugglers, drug dealers(who sell harder drugs) etc etc.
Stopping all that contaminated hash & weed on the streets aswell.
Just my 2 cents
