When heated (decarboxylation), THCa converts to Delta-9 THC. Hemp-derived THCa is federally legal under the 2018 Farm Bill when it contains <0.3% Delta-9 THC by dry weight. - **Is THCa legal?** Federally yes under the 2018 Farm Bill, but state laws vary. Check our [Legal Heatmap](https://www.thcvsthca.com/heatmap) for state-by-state status. - **THC vs THCa difference?** THCa is the raw acidic form; THC is the activated psychoactive form. They are chemically identical when heated. THCa products are often 40–60% cheaper than dispensary THC. - **Does THCa get you high?** Raw THCa is non-psychoactive, but when smoked or vaped, it converts to THC and produces psychoactive effects identical to traditional cannabis. - **How to dose cannabis?** Use our [Dosage Calculator](https://www.thcvsthca.com/dosage-calculator) for personalized recommendations based on experience, tolerance, body weight, and product type. - **What is a COA?** A Certificate of Analysis is a lab report verifying cannabinoid potency, terpene content, and safety testing.
