Unfortunately, as of right now, THC-O is off-limits in Alaska, Arizona, Arkansas, California, Colorado, Delaware, Idaho, Iowa, Mississippi, Montana, Nebraska, Nevada, and Utah. We encourage you to write to your legislators.
As of right now, THC-O is legal in the following states: Alabama, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Vermont, Virginia, Washington, West Virginia, Wisconsin, Wyoming.
The answer to that question is a bit more complicated. Even though THC-O is legal at the federal level, several states have, over the past year, made a push to ban or restrict the cannabinoid, despite its national status. The laws are changing all the time, meaning what is legal today could change tomorrow. We try to keep up-to-date as much as possible but recommend checking with local laws.
In 2018 Congress passed, and the President signed into law the Farm Bill of 2018. That bill (which is now law) legalized hemp and all of its compounds and derivatives. That included CBD and even THC-O. THC-O that comes from hemp is now legal.
Like all cannabinoids, there are no reports of anyone ever having an issue with THC-O. It is entirely 100% safe. Still, as with anything, you should always be careful. Use it in moderation, never take too much, and know your limits.
THC-O is made from hemp and is naturally occurring from hemp. Still, it is not a synthetic cannabinoid. It is all-natural. However, it does take some work in the lab to produce enough of this cannabinoid to make it viable to sell on the market.
