What is THCA flower?
THCA is a cannabinoid found naturally in raw hemp and cannabis. When THCA is heated, it converts to Delta-9 THC. Federal and state rules for hemp-derived THCA are changing, including a new federal hemp definition that takes effect November 12, 2026, so please check the current rules where you live.
Do I need to be 21 to order?
Yes. We only sell to adults 21 and older. You'll be asked to confirm your age when you visit the site.
Where can I see the lab results?
Open our lab report library and search by strain or product name. Many product pages also link straight to their certificate of analysis.
Can these products show up on a drug test?
They can. THCA converts to THC, and products made from hemp can lead to a positive drug test. Please don't use them if you are subject to testing.
Is it legal where I live?
Hemp laws are different from state to state and are changing at the federal level too. Please check your state and local laws before you order.
