Delta-9 Tetrahydrocannabinol (Delta-9 THC) is a major cannabinoid that is found in the cannabis plant. When people smoke marijuana and feel intoxication, this is mainly due to Delta-9 THC within the plant. Delta-9 THC is the main psychoactive compound in cannabis. It works with the human endocannabinoid system (ECS), which aids in regulation of physical and mental well-being, influences how people experience stress and anxiety, and relieves pain. It also is is known to aid in easing nausea and helps in sleep and relaxation.

The 2018 Farm Bill is the first piece of federal legislation legalizing hemp and removing it from the DEA's Schedule I Controlled Substance list. It allows up to .3% Delta-9 THC by dry weight to remain compliant. As an example, a 3 gram Delta-9 infused piece of caramel is within compliance if it contains under .3% Delta-9 THC, or 9 mg, by weight (3 grams x .3% = 9 mg). Using the 2018 Farm Bill as a guideline, companies are able to offer consumers potent, safe, and federally regulated Delta-9 products.
