How Hot is Too Hot?
When you start vaping, one of the more interesting and controversial topics that comes up is: "What temperature should I vape at?". There is no one answer and the answer depends on what your goals are. The answer may differ depending on what you are vaping. Dried herb of a particuualr strain may be best vaped at a certain temperature while another strain may have a different temperature. In the end there is no best temperature. The reason for this lies in the fact that all the various components of cannabis have different boiling points. When you smoke or "burn" a joint, you are getting all of the cannabinoids as well as some of the toxins created by combustion of both the cannabis and the paper. One of the major reasons people prefer vaping is to avoid these toxins as well as the extra heat from the hot smoke. Dry weed can begin to combust at around 200 °C. The maximum heat weed can take before burning is approximately 230 °C., depending on it's moisture content.
Higher temperatures (above 200°C) provide a higher ratio of the type of cannabinoids that have an effect on your body (CBD, CBN, CBC); Whilelower temperatures provide a higher ratio of the type of cannabinoids that have an effect on your mind and consciousness (THC).
- 160°C - 180°C: THC boils at 157C. Below that you are only getting a few terpenes. It will likely be delicious, but it will likely be dissapointing if you are looking for a kick. CBD boils between 160 and 180 C So if you stay under 180 you will get medicinal effects and some nice flavours because many of the terpenes hit their boiling points in this range.
- 180°C - 200°C:You will get a good flavour and a nice stone in this range. You will still get some nice flavour and more of a body stone because of some of the other cannabinoids and terpenes that have synergistic effects with THC. You won't be getting toxins like benzene. Many people consider this the ideal range. Benzene boils at 200 and the terpenoid linalool at 198 - so if you could dial in at 198 you would be getting the maximum range of cannibinoids and terpenoids without any of the toxic benzene.
- 200°C -220°C: You will feel more body effects in this rangeAt this point you will start getting toxins like benzene. They will be in concentrations that are far less than with smoking but they will be there nonetheless. Also if you are vaping anything made with solvents and they are of uncertain providence, you may want to keep this in mind.
- Above 220°C: Once you break 220 you are now getting CBC and THCV in relatively small doses but you will also be getting napthalene (218).So unless you want CBC and THCV you might as well stay below 218.These cannabinoids act in concert with THC and you wil feel more of a body stone. You will still be getting these toxins in doses that are far less than if you smoke your herb or concentrate, but they will be there nonetheless. If you smoke cigarettes as well, I wouldn't worry about any of this because the tobacco smoke is WAY more toxic than any vapining you will be doing.
