THCa is a non-intoxicating cannabinoid that can be found in raw, live cannabis. THCa is the acidic precursor to the more well known THC. As cannabis is cured THCa is slowly converted to THC. Heat from a lighter, a vaporizer, or an oven will speed up this conversion through a process known as decarboxylation. Without the decarboxylation process, THCa will remain non-intoxicating. THCa and THC are the most abundant cannabinoids found in cannabis with concentrations up to 40%. Many cannabis companies are now including THCa percentages in their cannabinoid testing breakdown. The THCa concentration is technically a more accurate label for flower that hasn’t been decarboxylated yet, meaning that you can include the THCa percentage when discussing THC percentages. According to Dr. Dustin Sulak, THCa displays numerous therapeutic benefits such as reducing nausea, vomiting, inflammation and pain. Dr. Ethan Russo states that THCa has the potential to help with weight loss, certain metabolic syndromes, Type 2 diabetes, and the treatment of cancer (3). A noteworthy feature of THCa is its ability to produce strong anti-seizure and anti-nausea effects at lower doses than THC (1, 2).
