20. Extraction Does Not Leave Behind Solvents

Wed Jun 18, 2025, 01:37 PM

Most extraction is done with ethanol, which is easily vacuum eliminated. What's left behind is in the ppb range.
Other processes use butane which is substantially more volatile, making removal even easier & more thorough.
Finally, some manufacturers use super critical CO2 to remove the THC. At room temperature, free CO2 is nearly instantly complete as long as some modest heating is done to prevent cooling by evaporation.
The scary word "chemicals" are not at issue with cannabis extracts
