What is THCa?

THCa — Tetrahydrocannabinolic Acid — is the raw, non-psychoactive compound found naturally in the cannabis plant. In its natural state it won't get you high. But when heat is applied through dabbing, vaping, or smoking, THCa converts to THC and becomes fully active. This process is called decarboxylation — and it's the foundation of how concentrates like rosin work.

Is THCa Legal?

THCa products are federally legal under the 2018 Farm Bill when derived from hemp and containing less than 0.3% Delta-9 THC by dry weight.

Laws may vary by state, so customers should always check local regulations before purchasing.
