A cannabis concentrate (also called marijuana concentrate, marijuana extract, or cannabis extract) is a highly potent tetrahydrocannabinol (THC) and/or cannabidiol (CBD) concentrated mass. Marijuana concentrates contain extraordinarily high THC levels that could once range from 40 to 80%, up to four times stronger in THC content than high grade or top shelf marijuana, which normally measures around 20% THC levels. By 2017, distilled concentrate was reportedly available at 99.58% THC content.
Volatile solvents such as ethanol, butane, propane and hexane are often used to prepare extracts, leading to fire and explosion hazards in uncontrolled environments.Super-critical fluid extraction using carbon dioxide alleviates concerns of fire and explosion and results in a high quality product.
Legally produced concentrates for retail sale in legalized states are often packaged in small lip-balm sized containers.]]
