Cannabis Extraction Techniques

Extraction techniques are used to separate the components of cannabis and remove them from the plant matrix. Various methods can divide cannabis plant material into parts, or extracts, that contain different chemicals.

What is a solvent extraction?

Solvent-based extraction can be defined as any method that uses a volatile chemical to dissolve the cannabinoid-packed trichomes away from the plant material. Once collected, the solvent is then removed, typically by means of evaporation (or purging), leaving behind a cannabinoid-rich concentrate.

What is a solventless extraction?

Solventless extracts, on the other hand, contain no solvents, and none were used in its production. So be careful, because solvent-free isn’t the same as solventless.

Solvent-free VS solventless

While solvent-based extracts can be considered to be any concentrate made using chemical assistance, compared to solventless extracts which do not things get a little confusing when it comes to the term “solvent-free”. Properly made solvent-based extracts have all of the solvents removed before being sold. This means that they can be labeled as solvent-free despite solvents being used in their manufacture.

Solvent-less: no solvents ever used
Solvent-free: solvents used then removed

  1. Hydrocarbon (butane, propane, n-tane, etc.)
  2. Carbon Dioxide (CO2)
  3. Ethanol (alcohol)
