People will still cry foul at the 0.12% of PG. Ridiculous, but that will be the claim.
proplyene glycol has been in every asthma and copd inhaler since the 50's . its basically a hygroscopic liquid.
in general, glycols are non-corrosive, have very low volatility and very low toxicity .
ethylene glycol is probably the only corrosive poisonous glycol to humans and animals.
"Propylene glycol is considered
generally recognized as safe (GRAS) by the
U.S. Food and Drug Administration, and it is used as an
humectant (E1520), solvent, and preservative in food and for tobacco products, as well as being one of the major ingredients of the "e-liquid" used in
electronic cigarettes along with
vegetable glycerin. It is also used in pharmaceutical and personal care products.[SUP]

solvent in many
pharmaceuticals, including
oral,
injectable and
topical formulations, such as for
diazepam and
lorazepam that are
insoluble in water, use propylene glycol as a solvent in their
clinical, injectable forms.[SUP]

I would love to learn how to truly isolate cbd (0%) for an Parkinson's patient. Trying to get 0% thc + high cbd, linalool, and myrcene into an oil. If you ever feel like sharing how to do this please hit me up.
its easier than you would think..... you would want to take harlequin or acdc/cannatonic high cbd strains and pick them before the trichromes cloud up preserving more of the cbd acids. then you would want to soak in an organic solvent that has a higher boiling point than cbd like limonene. limonene is non polar and wont boil out at the temps needed for cbd. actually limonene boils at 350 degrees while thc burns from 315-325 cbd from 320-350 with no vac. at 29.9 hg the heat required will be much less due to the atmospheric pressure being removed (vacuum). you distill it just like alcohol. exactly the same. temperatures are the key. once it starts to yield and u see oil condensing in your flask keep the heat at that temp. also u want to smell and taste it. if it tastes like limonene your too hot. since cbd boiling point almost reaches that of limonene you can tune your temps by raising it slowly until you get limonene distilled into your cbd. you can find the right temps based off that. and u can always re distill the limonene out! very simple. when i distill for capsules i actually want some of the limonene to be distilled into the mix. i add myrcene alpha pinene, beta pinene, carotine, phytols and a few other terpenes. all have individual medical qualities on their own but when you combine them with the ability to control strict % of each. you can create custom recipes for individuals with different diseases. cancer would need 1:1 ratio thc/cbd with more antioxidant terpenes and epilepsy would benefit from a fractional percentage of thc with high cbd and terpenes like myrcene that affect the blood brain barrier and brain more effectively (epilepsy is triggered by the part of the brain where cbd1 receptors are highest) so adding myrcene would allow more cbd absorbtion with lower dose. its really cool how it all works. its horrible that people like me and friends of mine who do the same thing get slandered by all of these hash makers who have no real arguement other than some marketing schemes. isolation of cannabinoids and the ability to break down even single isomers (the building blocks of terpenes and cannabinoids) is the future of cannabis medicine.. imagine what can be done when we can smash atoms and start combining isomers in ways nature hasnt for the cannabis plant. we could genetically engineer 75% cbd strains if the government wasnt treating marijuana as schedule 1 narcotics more illegal than cocaine meth and heroin combined according to the DEA.
basically get a 1000ml vacuum/fractional distillation glassware kit. soa
