In the U.S., this container garden would not be allowed, and could land one in jail for a long time. Some states are making cannabis legal; but, federal laws could be enforced, overruling state laws.

I am a supporter of the legalization of medicinal marijuana. Perhaps, someday planting 3-4 plants in a personal garden may become legal. The research seems to be gaining momentum for its health benefits for autistic children, and cancer patients.

Best regards.

Peace.
