Vaping Temperatures for Cannabis

Vaping cannabis is done by vaporizers, which work by heating up marijuana to the point where cannabinoids are turned into vapor. The  compounds “boil” and evaporate, leaving behind fibrous plant matter. When you light up cannabis, the smoke is a mix of cannabinoids and a number of somewhat toxic combustion by-products, such as PAHs. In fact, analysis has shown that joint smoke only contains 10% cannabinoids, the rest is combustion products. In contrast, the clouds coming from a vaporizer contain up to 95% cannabinoids, with only small traces of PAHs. An added benefit is the fact that your bud will last longer thanks to the lower temperatures used in your vaporizer.

Is there a perfect temperature?

This is probably one of the questions you’d like to ask, so here are the key findings:

There’s a temperature range in which different compounds of cannabis are released, each showing unique qualities in effect. While only experimentation will show you the high that suits you best, an ideal temperature to extract a wide range of psychoactive compounds is 365ºF. The optimal temperature range for cannabis is between 347ºF – 392ºF (175ºC – 200ºC). Temperatures below 374ºF (190ºC) tend to produce a more cerebral high while temperatures above that tend to induce a body high.

Cannabinoid Temperatures

The range of temperature is in which all cannabinoids evaporate lies between 314ºF (157ºC) and 428ºF (220ºC) . As all Cannabinoids have different boiling points, vaporizing the same load of herb at different temperatures will generate different results. In general, there’s two main effects, which is a cerebral high and a body high. As mentioned above, lower temperatures will have a heady effect, whilst higher temperatures will have a more body load effect.

Please note: Although some of the cannabinoids in these lists require temperatures about 392ºF (200ºC) to evaporate, vaping at that temperature runs the risk of causing combustion, which should be avoided.

Cannabinoid Vaping Temperature Effects
THC 314.6ºF


It has both euphoric and analgesic effects, inducing a great sense of relaxation.
CBD 320-356ºF


It partly counters the effects of THC, effectively countering feelings of anxiety and paranoia.
Delta-8-THC 347ºF-352.4ºF


This cannabinoid is very similar to THC, but it is more stable and less psychoactive. It has great anti-vomiting properties.
CBN 365ºF


CBN is often found in quite small amounts, however, its effects can still be felt. It breaks down THC and is highly associated with a sedative effect.
CBC 428ºF


This cannabinoid has anti-inflammatory and anti-fungal properties.
THCV 428ºF


THCV has been shown to moderate the psychoactive effects of THC, but more research is required.

Combustion: Dry weed can begin to combust at around 392ºF (200ºC). The maximum heat weed can take before starting to burn is around 446ºF (230 °C), depending on how dry your weed is.


Flavonoids, like terpenoids, are not that well known compared to cannabinoids. They are are a large class of plant pigments that are sometimes referred to as Vitamin P. Terpenoids and Flavonoids are partly responsible for the looks, taste and smell of a particular strain. they are the reason why cannabis enthusiasts take a whiff of a strain because their smell reveals a lot about the character of the plant.

They are also thought to have secondary health benefits, which will be explained in the following table:

Flavonoid Vaping Temperature Effects
Apigenin 352.4ºF


Apigenin is thought to be estrogenic, anxiolytic and have anti-inflammatory properties.
Beta-sitosterol 273.2ºF


This flavonoid is thought to have anti-inflammatory qualities.
Cannflavin A 359.6º


This flavonoid is a COX-2 inhibitor.
Quercetin 482ºF


Quercetin is an antioxidant and anti-viral flavonoid. It vaporizes in the combustion zone.


Terpenoids are structurally related to terpenes and are naturally occurring in a wide range of plants. They play a role in what gives plants their unique aromatic quality. The scent of cinnamon and menthol are examples of well known terpenoids.

The following table outlines the effects and vaporization temperature of terpenoids:


Terpenoid Vaping Temperature Effects
Beta-caryophyllene 390.2ºF


It is thought to be anti-inflammatory and anti-malarial.
Alpha-terpineol 312.8ºF


This terpenoid is an antioxidant, sedative, antibiotic and anti-malarial.
Beta-myrcene 330.8ºF – 334.4ºF

(166ºC – 168ºC)

This an analgesic, antibiotic and anti-inflammatory
Delta-3-carene 334.4ºF


This terpenoid has anti-inflammatory properties
1,8-cineole 348.8ºF


1,8-cineole increases cerebral blood flow,acts as a stimulant, and is anti-viral, anti-inflammatory and an antibiotic.
D-limonene 350.6ºF


D-limonene appears naturally in cannabis. It has anti-mutagenic, antidepressant and immune system potentiating properties.
P-cymene 350.6ºF


P-cymene is an antibiotic and an anticandidal agent.
Linalool 388.4º


This is an antidepressant, sedative and immune system potentiator.
Terpinol-4-ol 408.2ºF


This in an antibiotic and an acetylcholinesterase inhibitor.
Borneol 410ºF


Borneol s an antibiotic
Alpha-terpineol 422.6ºF


This terpenoid is a sedative, antibiotic, antioxidant and acetylcholinesterase inhibitor.
Pulegone 435.2ºF


Pulegone is a sedative and potentially has memory boosting properties


Toxins are chemicals that can be harmful to your body. The advantage of a vaporizer lies in its unique ability to extract the active ingredients of cannabis, but without the toxins of combustion, such as tar and carbon monoxide. In short, vaping does not expose your lungs to as much harmful chemicals as smoking does.

Vapor can still contain trace amounts of toxins. Compared to the over 100 different PAHs found in smoke, the one single PAH discovered in vapor is obviously a massive improvement. On the other hand, toxins that come from pesticides, herbicides and other chemical agents will also concentrate in vapor – making organic cannabis a smart choice.

The following is a small selection of some of the toxins that are released through combustion:

Toxin Temperature Effects
Toluene 230ºF


This is not thought to be a serious toxin, and it is only present in trace amounts. It can lead to lightheadedness, nausea, sleepiness and a loss of appetite
Benzene 176ºF


Benzene is a carcinogen
Naphtalene 424.4ºF


This toxin is possibly a carcinogen and causes lightheadedness, nausea, loss of appetite and pale skin.

Cannabis Moisture and Vaporizer Temperature

When you use a bong or smoke a joint, extremely dry cannabis ruins your whole smoking experience. Vaping it is still a delightful experience. The dryness, however, will cause it too vaporize much faster. If it is too hot, you run the risk of flash boiling the active ingredients, eliminating the taste and flavor of your bud. As it is largely dependent on the situation and strain you are using, there is no definitive guide on how you can vaporize particularly dry weed.

Note: Set your temperature lower judging by how dry your weed is. It might take a bit of practice at first but once you get the hang of it, you won’t have to worry about flash boiling it.

Conversely, if your bud is fresh, it may be very high in moisture. As a result, it can sometimes be hard to vaporize it efficiently. To deal with this, you can set your vape between 280ºF (138ºC) to 298ºF (148ºC). You’ll gain a load of flavonoid vapor whilst slowly drying out your cannabis. After you did this, your pot should be dry enough to vaporize efficiently at the cannabinoid temperatures.
