How do you extract THC from a stock?

To extract THC from cannabis, one common method is to use a solvent such as ethanol, butane, or CO2. The cannabis plant material is soaked or washed with the solvent, which dissolves the THC and other cannabinoids. After extraction, the solvent is evaporated, leaving behind a concentrated THC extract. It's important to follow safety protocols and legal regulations, as some extraction methods can be hazardous.
