If cannabis would be legalized, governments would be facing a challenge of trying to get taxes - first of all - from the companies importing and second of all, from the growers. It would be impossible to legalize it and ilegalize growing. The legalizing issue is about common acceptance. In Finland it's legal to grow one marijuana plant for "decoration" as long as you don't cut it. I grow one on my front yard. I never cut it. It's just there for people to see how beautiful it is. If every pro-legalize fin would have a plant growing on their front yard, it would become accepted then legal and then an institution. IMHO
