There are many different types of concentrated cannabis extracts, each with its own unique set of benefits. Some of the most common include hash oil, wax, shatter, and BHO (butane honey or hash oil). Concentrated cannabis extracts are made by extracting the cannabinoids and other active compounds from the plant material. This can be done using a variety of methods, but the most common is through the use of solvents like butane or CO2. The resulting extract is then typically further processed to remove any residual solvent and impurities. Concentrated cannabis extracts are especially beneficial for patients who need high doses of cannabinoids to treat their condition. Below you will find our cannabis extract reviews and photos.
