GOLDEN GARDENS · CANNABINOID SCIENCE

Cannabinoid Activation & Vaporization Points

Explore the temperatures where ten well-known cannabinoids activate or rapidly volatilize into an inhalable vapor—from THCA’s decarboxylation point to the higher thresholds for CBC and THCV.

Turn up the heat on cannabinoid science: use our Cannabinoid Activation & Vaporization Tool to see when THCA activates and where THC, CBD, CBG, CBN, THCV and more rapidly volatilize into an inhalable vapor.

01

Activation

Raw cannabis contains mostly acidic cannabinoids such as THCA and CBGA. Heat removes a carboxyl group, converting them to THC and CBD.

02

Vaporization

Once activated, each cannabinoid has its own threshold where it rapidly volatilizes into an inhalable vapor.

03

Degradation

Prolonged heat, light and oxygen can change cannabinoids further. THC, for example, can slowly oxidize into CBN over time.

Understand the science

Does decarboxylation happen at one exact temperature?

No. Temperature changes the reaction rate, while time and sample conditions affect how far conversion proceeds. Published laboratory work shows temperature-dependent reaction kinetics. A temperature reading alone cannot establish complete conversion.

Can this chart tell me how much THC I will get?

No. Retention requires measurements under defined conditions. This explorer compares temperature with commonly cited thresholds; it does not calculate conversion, loss, degradation, or product potency. Check each product’s Certificate of Analysis for its measured cannabinoid content.

Why only ten cannabinoids?

More than 100 cannabinoids have been identified, but most exist in such small amounts that they cannot be isolated cleanly enough to measure distinct thermal thresholds, and they break down quickly when heated at normal pressure. These ten are the best known and most researched. Values can differ between charts depending on pressure, purity and the original source.

Sources & reference values

Values are approximate and compiled from commonly cited references, including McPartland & Russo (2001) for THC, CBD, Δ8-THC, CBN, CBC and THCV. Published decarboxylation kinetics show THCA conversion speeds up across roughly 80–160°C rather than at one exact point. The chart uses the midpoint when a range is reported.
