THCA: Tetrahydrocannabinolic Acid
THCA is the most abundant cannabinoid in raw cannabis, with concentrations ranging from 1-35%. It is the direct precursor to THC, meaning it converts into THC when heated (through a process called decarboxylation). Until it has been decarboxylated and converted into THC, THCA itself doesn’t cause the "high" associated with cannabis administration, but may still offer some of the potential therapeutic benefits.
How is THCA different from THC?
All cannabinoids in raw, unheated cannabis exist in their acidic form, meaning they have a carboxyl group attached to them. This includes THCA, CBDA, CBGA, and many others. When heated, the carboxyl group is removed through decarboxylation, converting these acidic cannabinoids into their non-acidic form.
Does THCA have any medical benefits?
Research into THCA is still ongoing, but early studies suggest it may offer many of the same therapeutic benefits as THC, including anti-inflammatory, anti-emetic, and neuroprotective properties.
Can I take THCA without getting 'high'?
Yes, as long as the THCA is not heated in any way. Raw cannabis contains high levels of THCA, and consuming it through methods such as juicing or eating it raw will not produce psychoactive effects. Once heated (decarboxylated), the THCA converts into THC, which is the compound primarily responsible for the "high" associated with cannabis.
