The molecular map of cannabinoids stretches far and wide, and laboratories are manipulating them faster than the law can track. Chemists have discovered how to create forms of THC that are chemically different from Delta-9 THC — the form of THC largely produced in cannabis — but carry similar intoxicating effects. Delta-8 and Delta-10 THC aren't explicitly outlawed by the Controlled Substances Act, and they can be produced with industrial hemp, a plant now legally grown at the federal level. (This is done by extracting CBD from industrial hemp and then converting the CBD into the "new" forms of THC with acetic acid.)
