Device to vaporize substances for inhalation A vaporization heat wand and vaporization chamber bowl used to deliver vapor through a water pipe A vaporizer or vaporiser, colloquially known as a vape, is a device used to vaporize substances for inhalation. Plant substances can be used ...
The aromatic terpenoids begin to vaporize at 126.0 °C (258.8 °F), but the more bioactive tetrahydrocannabinol (THC), and other cannabinoids also found in cannabis (often legally sold as cannabinoid isolates) like cannabidiol (CBD), cannabichromene (CBC), cannabigerol (CBG), cannabinol (CBN), do not vaporize until near their respective boiling ...
Cannabidiol (CBD) is a phytocannabinoid, one of 113 identified cannabinoids in cannabis plants, along with tetrahydrocannabinol (THC), and accounts for up to 40% of the plant's extract. [17] Medically, it is an anticonvulsant used to treat multiple forms of epilepsy. [4]
36. Flame filter prevents flame from igniting herb which instead is heated to vaporization temperature. A vaporizer heats herbal cannabis to 157–210 °C (315–410 °F), which causes the active ingredients to evaporate into a gas without burning any plant material (the boiling point of THC is 157 °C (315 °F)).

Evaporation is a phase transition from the liquid phase to vapor (a state of substance below critical temperature) that occurs at temperatures below the boiling temperature at a given pressure. Evaporation occurs on the surface. Evaporation only occurs when the partial pressure of vapor of a substance is less than the equilibrium vapor pressure ...

CBD heated to 175, [13] or 250–300 °C may partially be converted into THC. [14] Even at room temperature, trace amounts of THC can be formed as a contaminant in CBD stored for long periods in the presence of moisture and carbon dioxide in the air, with storage under inert gas required to maintain analytically pure CBD.
