THCa flower is raw, unheated cannabis that contains tetrahydrocannabinolic acid (THCa), the natural, non-psychoactive form of THC. When smoked, vaped, or heated, THCa converts into Delta-9 THC, delivering traditional cannabis effects. Until it’s decarboxylated, THCa offers potential benefits without a high.

Under the 2018 Farm Bill, hemp-derived THCa flower is federally legal as long as it contains less than 0.3% Delta-9 THC by dry weight. However, laws vary by state, and some have restrictions on high-THCa products. Be sure to check your state’s regulations before purchasing.

THCa is the raw, acidic form of THC. It is non-psychoactive until it undergoes heat (decarboxylation), converting to Delta-9 THC. Delta-9 is the compound responsible for the “high.” THCa allows users to benefit from cannabinoids with more control over psychoactivity.

Only if it’s heated. THCa itself won’t get you high, but when you smoke, vape, or cook it, the THCa converts to Delta-9 THC — delivering the same effects as traditional cannabis flower.

THCa flower can be smoked, vaped, or infused into edibles (with proper decarboxylation). You can roll it, pack it in a bowl, or use it with dry herb vaporizers. Just like regular cannabis, it’s best to start slow and find the right dose for your tolerance.
