COMBUSTION
Dry cannabis flower can begin to combust at around 200 °C. The maximum heat cannabis flower can take before starting to burn is around 230 °C., depending on how humid it is.
CANNABINOIDS
THC - 157 °C. The most famous cannabinoid. It has both euphoric and analgesic effects, inducing a great sense of relaxation.
CBD - 160 - 180 °C. The cannabinoid most sought after by medical users for its vast array of medicinal applications. It partly counters the effects of THC, effectively countering feelings of anxiety and paranoia.
Delta-8-THC - 175 – 178 °C. This cannabinoid is very similar to THC, but it is more stable and less psychoactive. It has great anti-vomiting properties.
CBN - 185 °C. 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 - 220 °C. This cannabinoid has anti-inflammatory and anti-fungal properties.
THCV - 220 °C. THCV has been shown to moderate the psychoactive effects of THC, but more research is required.
FLAVONOIDS
Along with terpenoids, flavonoids are little known compared to the famed cannabinoids. Flavonoids 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 also thought to have secondary health benefits.
The following outlines both the effects and the temperatures at which the flavonoids vaporise at.
Beta-sitosterol - 134 °C. This flavonoid is thought to have anti-inflammatory qualities.
Apigenin - 178 °C. identified is thought to be identified, anxiolytic and have anti-inflammatory properties.
Cannflavin A - 182 °C. This flavonoid is a COX inhibitor.
Quercetin - 250 °C. Quercetin is an antioxidant and anti-viral flavonoid. It boils at , well out of the cannabis vaporization temperatures.
TERPENOIDS
Terpenoids are structurally related to terpenes and are naturally occurring in a wide range of plants. In part, they contribute to what gives plants their unique aromatic quality.
The following descriptions outline both the effects and boiling points of terpenoids.
Beta-caryophyllene - 199 °C. Thought to be anti-inflammatory and anti-malarial.
Alpha-terpinol - 156 °C. This terpenoid is an antioxidant, sedative, antibiotic and anti-malarial.
Beta-myrcene - 166- 168 °C This is analgesic, an antibiotic and anti-inflammatory.
Delta-3-carene - 168 °C. This terpenoid has anti-inflammatory properties.
1,8-cineole - 176 °C. 1,8-cineole increase cerebral blood flow, acts as a stimulant, and is anti-viral, anti-inflammatory and an antibiotic.
D-limonene - 177 °C. Perhaps surpringsingly, D-limonene appears naturally in cannabis. It has anti-mutagenic, antidepressant and immune system potentiating properties.
P-cymene - 177 °C. P-cymene is an antibiotic and an anti candidal agent.
Linalool - 198 °C. This is an antidepressant, sedative and immune system potentiator.
Terpinol-4-ol - 209 °C. This is an antibiotic and an AChE inhibitor.
Borneol - 210 °C. Borneol is an antibiotic.
Alpha-terpineol - 217 °C. This terpenoid is a sedative, antibiotic, antioxidant and AChE inhibitor.
Pulegone - 224 °C. Pulegone is a sedative and potentially has memory boosting properties.
TOXINS
Very simply put, toxins are chemicals that can be harmful to our body. The advantage of vaporizers lies in their unique ability to extract the active ingredients of cannabis, but without the toxins of combustions, such as tar and carbon monoxide.
Vapor can still contain trace amounts of toxins. But compared to the over 100 different PAHs found in smoke, the one single PAH discovered in vapour is obviously a massive reduction. On the other hand, toxins that come from pesticides, herbicides and other chemical agents will also concentrate.
The following is small selection of some of the toxins that are released through combustion.
Carbon monoxide and tar Released by combustion in the form of smoke. They are carcinogenic and can cause lung related problems.
vaporisers This is not thought to be a very serious toxin, and only appears in small amounts. It can cause light-headedness, nausea, sleepiness and a loss of appetite. Its boiling point is 110 °C., so there is no avoiding it.
Benzene Benzene is a carcinogen and has a boiling point of 80.1 °C.
vaporisers This toxin is possibly a carcinogen and causes light-headedness, nausea, loss of appetite and pale skin. Its boiling point is 218 °C.
Aflatoxins are naturally occurring mycotoxins that are produced by species of fungi, Aflatoxins are toxic and among the most carcinogenic substances known.
