A recent study here in Europe as found that some low-quality CBD e-liquids contain traces of solvent (used to extract said CBD) that are above safety level and may trigger adverse reaction in vapers. I assume THC e-liquid goes through the same sort of process and may have the same issue.
- tapland 7y agoI would love it if you had a link to that study. A relative of mine is on the lookout for CBD oils and I said I'd help find what there is.
- Hasknewbie 7y agoI don't have a direct link to the study, but this is from the BBC (https://www.bbc.com/news/health-48950483 https://www.bbc.com/news/health-48950483): "The researchers also found the presence in seven products of the solvent dichloromethane, which can cause wheezing and shortness of breath, at levels above food safety limits."
- Scoundreller 7y agoAre food safety limits the appropriate limit for something that will be largely exhaled?
- buttcoinslol 7y agoYes, residual solvents are possible with the THC extraction process. I prefer to use THC concentrates extracted with CO2 to avoid inhaling residual solvents.
- robocat 7y agoCan you tell only CO2 was used?
- whenchamenia 7y agoCo2 iirc is a physical extraction, like bubble hash, while this is concerning solvent hash, a different product. The correct way to extract solvents is under vacuum.
- ficklepickle 7y agoSupercritical CO2 is a (very non-polar) solvent. I can't imagine what would make that a physical or mechanical extraction. Good CO2 extraction uses two passes at different pressures. One to extract the terpenes and one for the cannibinoids.
