Delta-9 THC (tetrahydrocannabinol) is a psychoactive compound found in cannabis plants, including hemp plants. While both marijuana and hemp are species of the Cannabis sativa plant, they differ in their levels of delta-9 THC and are regulated differently under the law.

In the United States, hemp is defined as a cannabis plant that contains less than 0.3% delta-9 THC by dry weight. This means that hemp plants are not considered to be psychoactive and are not subject to the same regulations as marijuana plants, which can contain higher levels of delta-9 THC.

Hemp-derived products, including hemp-derived delta-9 THC, are legal in the United States under the 2018 Farm Bill, as long as they meet the requirements for hemp. These products can be sold and consumed in states where marijuana is not legal, and they do not produce the same psychoactive effects as marijuana.

Hemp-derived delta-9 THC is often used as a dietary supplement or for recreational purposes. It is available in a variety of forms, including tinctures, oils, capsules, and edibles. Some people use delta-9 THC for its potential health benefits, including reducing anxiety, relieving pain, and improving sleep. However, the scientific evidence for these benefits is limited and more research is needed to fully understand the effects of delta-9 THC.

While hemp-derived delta-9 THC is legal in the United States, it is still a controlled substance and should be used with caution. More research is needed to fully understand the potential health benefits and risks of delta-9 THC.
