Hemp is a versatile plant that can be used for a wide range of industrial and medicinal uses. The legal status of hemp in the US has changed significantly in recent years. In 2018, Congress passed the Agricultural Improvement Act, also known as the Farm Bill, which removed hemp from the list of controlled substances and legalized it at the federal level. This means that hemp can be grown and cultivated legally in all 50 states.
However, the 2018 Farm Bill also gave individual states the authority to regulate hemp production within their borders. As a result, the legality of hemp varies from state to state. Here is an overview of the current legal status of hemp in each state and the allowed THC percentages:
