Tetrahydrocannabinol, or THC, is the psychotropic ingredient in marijuana.
Marijuana concentrates have very high levels of THC.
Solvent-based products tend to be especially potent, with THC levels documented at an average of about 54-69% and reported to exceed 80%, while non-solvent based extraction methods produce average THC levels between 39-60%. In comparison, the THC content in marijuana plant material, which is often used in marijuana cigarettes, is lower—with samples seized by the U.S. Drug Enforcement Agency averaging just over 15%.
- Exposure to high levels of THC increases the risks of physical dependence and addiction. Higher doses of THC are more likely to produce anxiety, agitation, paranoia, and psychosis.
