PIE-neen
The forest terpene. Bronchodilator, memory enhancer, and natural counterbalance to THC-induced memory impairment.
Alpha-pinene is the most abundant terpene in nature and the primary component of pine tree resin. It is a bronchodilator, memory enhancer, and anti-inflammatory — and uniquely counteracts THC's short-term memory impairment.
Alpha-pinene is the most widely occurring terpene in the plant kingdom, found in pine trees, rosemary, eucalyptus, and many cannabis strains. Its distinctive fresh, piney aroma is one of the most recognizable scents in nature.
Pinene's most pharmacologically significant property is its ability to inhibit acetylcholinesterase — the enzyme that breaks down acetylcholine, the primary neurotransmitter for memory and cognition. This makes pinene a natural memory enhancer and, crucially, a counterbalance to THC's acetylcholinesterase-inhibiting effects that cause short-term memory impairment.
As a bronchodilator, pinene opens airways and increases airflow to the lungs. This property has been used in traditional medicine for respiratory conditions and may partially explain why some cannabis users report improved breathing. Pinene also has significant anti-inflammatory and antibacterial properties.
High-pinene strains are associated with alert, focused, clear-headed effects — the opposite of the foggy, memory-impaired experience associated with high-myrcene strains. This makes pinene-dominant strains popular for daytime use and productivity.
To maximize Pinene in your vapor, set your vaporizer to just above its boiling point:
Lower temperatures preserve more terpenes; higher temperatures extract more cannabinoids.
