Delta-9 THC has long been the face of cannabis. It’s what most people think of when they hear “THC,” and it’s responsible for the euphoric high associated with marijuana. But thanks to modern science and hemp legislation, Delta-9 THC is now available in federally legal forms derived from hemp—giving consumers across the U.S. new ways to enjoy it.
This guide breaks down the basics of Delta-9 THC, how it compares to other cannabinoids, where it’s legal, and the best ways to consume it.
How Delta-9 THC Works
Delta-9 interacts with the CB1 receptors in the brain, which regulate mood, appetite, memory, and pain perception. When consumed, it alters neurotransmitter function to produce the familiar cannabis high.
Common Effects:
-
Euphoria
-
Relaxation
-
Altered sensory perception
-
Increased appetite
Legal Status
Delta-9 THC is federally legal when hemp-derived and present in no more than 0.3% per dry weight.
Example:
A 5g gummy containing 10mg Delta-9 THC is legal because the THC content is <0.3% of total weight.
