Cannabinoids (18)

Cannabinoid Family Tree biosynthetic pathway shows how the major cannabinoids are produced by the plant itself

The Cannabinoid Family Tree

Above is a Family Tree of the major cannabinoids - scientists call it the biosynthetic pathway. Most of these cannabinoids are created by the actual cannabis and hemp flowers, however some are manufactured from CBD. As you learn more about cannabinoids, please remember that they really can affect people very differently. 

Cannabinoids are Bisphasic

Please also keep in mind that many of the cannabinoids are considered BIPHASIC, meaning a small dose may have one effect, but a large dose may have the opposite effect. That's why the phrase, "start LOW (dose) and go SLOW (increasing that dose)" is so important.

There probably is a "sweet spot" cannabinoid amount for your goals that is likely NOT the same sweet spot as your best friend. We all have a unique body chemistry and have different expectations and goals.

Boiling Points of Cannabinoids

We do not include the boiling points of the cannabinoids because they are very high and:

"There is no practical direct way of measuring the temperature at which the vapor pressures of THC and CBD reach normal room pressure (about 760 torr) [boiling point], since at such elevated temperatures, these cannabinoids are instable and decompose." - Vapor Pressure, Vaping, and Corrections to Misconceptions Related to Medical Cannabis' Active Pharmaceutical Ingredients' Physical Properties and Compositions, Aharon M.

He have a summary of the above paper here.

But the evidence is fairly clear that the accepted "common knowledge" boiling points of most cannabinoids are not accurate. The true boiling point temperatures of cannabinoids at atmospheric pressure are over 400C, or 752F. 

You don't need to "boil" to get vapor

However, matter doesn't need to reach its boiling point to vaporize through evaporation. When a substance vaporizes at temperatures below its boiling point, it is just called evaporation and it is very common. A pot of water will eventually completely evaporate, even at room temperature - and it happens very fast at elevated temperatures.

We know from a previous study on vaporizers that cured cannabis flower heated to 210C (410F) for 3 minutes will convert between 55% and 83% of THC into vapor, and between 46% and 70% of CBD into vapor.

Terpenes Vaporize First

Terpenes have much lower boiling points than cannabinoids, and will evaporate much faster than cannabinoids. That's probably why the first part of a bowl, joint, or vape tastes better than the last: you're getting most of the terpenes at the beginning. The authors of the study quoted above found that "the vast majority of the terpenes are inhaled before a significant fraction of the cannabinoids".

Just remember: Lower boiling point substances will evaporate faster at ANY given temperature.

 

The cannabinoid colors on this page represent their place in The Family Tree: 

  • Stage 1: Precursor Acids (Purple)
  • Stage 2: Acids (Blue)
  • Stage 3: Neutral (Green)
  • Stage 4: Oxidized (Orange)

STAGE 1: Precursor Acidic Cannabinoids

These two acidic cannabinoids are the ancestors to all the other cannabinoids in this family tree. They specifically create other acidic cannabinoids that will be present in high concentrations in raw and cured flower. These acidic cannabinoids get "decarbed" (usually by applying heat) and turn into the neutral cannabinoids like THC and CBD. All of the acidic cannabinoids are water soluble, unlike the neutral and oxidized cannabinoids which are only soluble in oil (lipophilic).

NONE of the acidic cannabinoids are psychotropic or euphoric. Only a few of the neutral cannabinoids, namely Delta-9 THC, Delta-8 THC & some of the "manufactured" cannabinoids are psychotropic or euphoric (that we have discovered so far). 

CBG-A, Cannabigerolic Acid
Reported Benefits: analgesic (pain reduction), anti-diabetic, antimicrobial, anti-tumor, antiviral, anti-inflammatory, gastrointestinal aid/nausea, hypertension relief

CBGV-A, Cannabigerovarinic Acid
Reported Benefits: anti-inflammatory (very limited research)

STAGE 2: Acidic Cannabinoids

The stage 2 acidic cannabinoids below are the direct parents of the most well-known cannabinoids, THC and CBD. These "acids" are what The Amazing Flower actually produces. Then AFTER blooming and harvest, these acidic compounds naturally transform into the neutral cannabinoids when heated (smoking, vaporizing, or baking) or exposed to light, time, and oxygen.

So remember, The Amazing Flower DOES NOT actually produce ANY psychotropic or euphoric compounds! It needs help to do that. ONLY Delta-9 THC, Delta-8 THC & THCV are psychotropic/euphoric (that we have discovered so far).

CBC-A, Cannabichromenic Acid

Reported Benefits: analgesic (pain reduction), anti-inflammatory, antimicrobial, neurological aid

CBD-A, Cannabidiolic Acid 
Reported Benefits: antiemetic (reduces nausea), anti-inflammatory, antiviral, antispasmodic, anti-tumor, gastrointestinal disorder relief

CBL-A, Cannabicyclolic Acid
Reported Benefits: anti-inflammatory, anti-tumor, (very limited research) 

CBN-A, Cannabinolic Acid 
Reported Benefits: very little research available
 

THC-A, Delta-9 Tetrahydrocannabinolic Acid

Reported Benefits: antiemetic (reduces nausea), anti-inflammatory, antispasmodic, anti-tumor, antiviral, gastrointestinal aid, sedative (sleep aid) 

THCV-A, Delta-9 Tetrahydrocannabivarin Carboxylic Acid
Reported Benefits: analgesic (pain reduction), anti-inflammatory, appetite suppressant, sedative (sleep aid)

STAGE 3: Neutral Cannabinoids (Decarboxylated, or "decarbed") 

Diagram of acidic cannabinoid molecules becoming "decarbed" by losing their carboxyl group of molecules
  

These neutralized (they are no longer acidic) cannabinoids have been studied the most and have different effects than their acidic parents. They are "fat soluble" so they don't mix well with most of the liquids humans naturally drink. If you swallow (ingest) a neutral cannabinoid, it has been shown that more of the neutral cannabinoids get into your bloodstream if you take them with fatty foods or drinks (think coffee with cream, hot chocolate).

CBC, Cannabichromene

It also seems to help dogs (a nice overview article about CBD & dogs is here).
