Not sure how the government was able to give itself the right to outlaw and punish people for the possession, use, or cultivation of something which grows naturally in MOST of the world and was used for thousands of years by people in various cultures.
But leave it to the US government, they’ll come up with some creative way to declare CO2 a hazard and dangerous substance they get to regulate.
Belladonna grows naturally too, so do coral snakes and rattlesnakes.
What a foolish notion that if it is in nature it is ok to put in our bodies.
