The US Food and Drug Administration issued its first warning to makers of products containing delta-8 THC, a cannabis compound that induces a “high” but falls within a legal loophole in the US.
Delta-8 THC is a compound closely related to delta-9 THC, the main psychoactive ingredient that gives marijuana users a high. It can be derived from a similar part of the marijuana plant as CBD, a non-psychoactive compound, and that is part of the reason why it falls into a legal gray area.
