Would cannabis have passed this point if it could be openly, legally transported across state lines and national borders? I'm very skeptical. The supply chain there is not just weak, it is actively antagonized by various police forces. My guess is that if cannabis was 100% legal, the indoor grow operations would not make economic sense; we'd just have giant farms or greenhouses in mexico or the southwest.
