The terpenes in THC can limit the negative intoxication and improve therapeutic value if approached properly through the process of dabbing at low temperatures rather than high.
Terpenes play a considerable role in tempering the intoxicating effects of THC and creating synergy with phytocannabinoids to increase their therapeutic value.
Dabbing describes the act of inhaling vaporized cannabis concentrates through a temperature-specific heating method such as a dab rig, e-rig, or vaporizer. Dabbing concentrates at high temperatures results in a smooth, cannabis vapor-rich accentuating the underlying terpene flavors.
Unfortunately, terpenes can produce toxic chemicals when super-heated. According to a study from Portland State University, vaporizing terpenes at the high temperatures may produce the toxicants methacrolein and benzene, which have been linked to certain cancers, even if used in a vaporizer.
So, if you want to enjoy a flavorful dab without heating the terpenes to toxicity, dab at as low a temperature as possible. Higher temperature results in unintended toxins, some of which can leave a varnish-like residue on delicate lung tissue.
