In most places in the United States it is legal to consume these products, but some states have banned their use. For this reason, it is important to do research about the federal laws that you have in your city before making use of any of the hemp derived cannabinoids like THC-P.
The United States is a very large country with different laws applicable to each state, so in some places consuming THC-P, Delta-8 or Delta-9 THC is not allowed. Always be careful and keep up to date with the new laws to be able to continue consuming what you want calmly. What we do know for sure is that it is okay to consume in California, Oregon and Arizona, but in other places it can vary, so be careful. You should always consume responsibly.
