It might surprise you to learn that, by the letter of the law, all Americans could be arrested by the U.S. federal government and charged with felony drug possession because all humans possess a Schedule I substance in their brains, reports Natural News.
Dimethyltryptamine, or DMT, is a Schedule I substance according to the Drug Enforcement Agency (DEA).
Schedule I drugs are defined as: “Unless specifically excepted or unless listed in another schedule, any material, compound, mixture, or preparation, which contains any quantity of the following hallucinogenic substances, or which contains any of their salts, isomers, and salts of isomers whenever the existence of such salts, isomers, and salts of isomers is possible within the specific chemical designation.”
Scientific American reports:
DMT is the only psychedelic known to occur naturally in the human body. In 1972, the Nobel laureate Julius Axelrod of the National Institutes of Health discovered DMT in human brain tissue.
DMT, also called the "Spirit Molecule," can be used in combination with various consumable items such as tea and used to go on a hallucinogenic drug trip, which is most likely why it is on Schedule I.
While the U.S. government could argue this applies only to synthetic DMT, that's not what the Schedule I lists. It simply says Dimethyltryptamine (DMT) and does not specify a synthetic type.
On a molecular level, drug laws actually ban certain arrangement of elements in a molecule, which makes that molecule criminal. An illegal molecule may have all the same elements of a legal molecule, but are just strung together in a different way.
When a government outlaws certain molecules, it is essentially criminalizing the order and arrangement of elements which are, by themselves, completely legal.
