Cannabis concentrate, also called marijuana concentrate, marijuana extract, or cannabis extract, is a tetrahydrocannabinol (THC) and/or cannabidiol (CBD) concentrated mass. Cannabis concentrates contain high THC levels that range from 40% to over 90%, [ 1 ] [ 2 ] stronger in THC content than high-grade marijuana, which normally measures around ...
However, due to first-pass metabolism in the liver and the high lipid solubility of THC, only about 5 to 20% reaches circulation. [3] [21] Following oral administration, concentrations of THC and its major active metabolite 11-hydroxy-THC (11-OH-THC) peak after 0.5 to 4 hours, with median time to peak of 1.0 to 2.5 hours at different doses.
Samples seized across the United States by the Drug Enforcement Administration over an 18-year period (1980–1997) showed that THC content in hashish and hashish oil averaging 12.9% and 17.4%, respectively, did not show an increase over time. [7] The highest THC concentrations measured were 52.9% in hashish and 47.0% in hash oil. [8]
The UNODC states that cannabis often contains 5% THC content, resin "can contain up to 20% THC content", and that "Cannabis oil may contain more than 60% THC content." [145] Studies have found that the potency of illicit cannabis has greatly increased since the 1970s, with THC levels rising and CBD levels dropping.
C. indica strains are frequently cross-bred with C. ruderalis to produce autoflowering plants with high THC content, improved hardiness and reduced height. [19] [20] Cannabis x intersita Sojak, a strain identified in 1960, is a cross between C. sativa and C. ruderalis. [3]

Δ-8-tetrahydrocannabinol (delta-8-THC, [a] Δ 8-THC) is a psychoactive cannabinoid found in the cannabis plant. [1] It is an isomer of delta-9-tetrahydrocannabinol (delta-9-THC, Δ 9-THC), the compound commonly known as THC, with which it co-occurs in hemp; natural quantities of ∆ 8-THC found in hemp are low.
