Many medical and recreational cannabis consumers prefer to inhale a cool, instantly-rejuvenating, cannabinoid-infused vapor as opposed to the comparably harsh combusted cannabis smoke.
However, many health-conscientious cannabis concentrate consumers—you included, perhaps—prefer to avoid all together inhaling residual petroleum particles from butane hash oil into their lungs. We couldn’t agree more.
So are you ready for a cleaner, purer, tastier, safer and overall truly higher-quality cannabis concentrate? Well, have we got a treat for you: supercritical CO2 extraction!
That’s not actually the treat, though. Rather, it’s a really awesome way to remove all the stuff that makes ganja great from the plant matter on which it resides. That way, you don’t have to burn your marijuana to reap all the mind-altering and medicinal benefits.
And best of all for those health-conscious cannasseurs out there, this extraction method won’t leave behind trace amounts of toxins in the finished product. Now that’s something to sit up and take notice of.
This post will break down a bit of the basics behind supercritical fluid extraction and the biochemical benefits of CO2 extracted cannabis concentrates. We’ll also leave you with some simple steps for extracting your own concentrated kief crystals at home using dry CO2 ice.
The Added Value of CO2 Extraction
Supercritical CO2 is increasingly being used as a cheap, recyclable, and environmentally safe industrial solvent for creating high quality:
- Fruit and nut extracts
- Fruit and nut aromas
- Omega-3 oils
- Tobacco extractions for e-cigarettes
- Hop-oil extraction for beer
- Oil extractions from algae (as an alternative energy source)
- Cannabis oil
You may look at that list and say, “Hey, it’s cool that CO2 extraction is being used for so many different products. But why, exactly, is it so popular?” Great question! Here’s the deal.
- Our bodies naturally produce carbon dioxide (CO2) when we breathe so it’s considered a “natural” product. This is in
