In America, "certain conditions" equates to "certain taxation".
Regulating it (like alcohol and tobacco) would be better than
keeping it illegal, but the best remedy would be to totally
decriminalize it and leave it free to grow and use.
It would be a hell of a way to increase our tax revenue & clear some of the non-violent drug offenders from jail, but true drug lords are never going to allow that to happen because their making to much money which equates to Politicians making to much money to allow it to happen.
