Present day use of solvent extraction in cannabis extraction

Organic hydrocarbon solvents offer key benefits in cannabis extraction for patients, manufacturers and policymakers alike.

Organic solvent-based extraction is very common throughout the chemical, food, personal care, pharmaceutical and perfumery industries as well as many others. The modern cannabis industry has essentially repurposed current methodologies from these previous industries. Cannabis extraction using organic solvents is easily comparable to the making of absolutes for the personal care and perfumery industries. An absolute is a concentrated, highly aromatic oil extracted from plants.

‘First, an organic solvent, such as hexane, is added to the plant material to help extract the non-polar compounds. This solution is filtered and concentrated by distillation to produce a waxy mass called concrete. The more polar, fragrant compounds are extracted from the concrete into ethanol. When the ethanol
