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 ...
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]
These are achieved at lower doses, because many synthetic cannabinoids are more potent than marijuana, and users are often unaware of exactly what they are getting and how potent it is. [62] For example, Δ 9-THC has an EC 50 of 250 nM at CB 1 and 1157 nM at CB 2, whereas PB-22 has an EC 50 of 5.1 nM at CB 1 and 37 nM at CB 2. [8]
Delta-8 THC has garnered attention in recent years thanks to a loophole in the 2018 farm bill, which legalized hemp, defined as a cannabis plant that contains less than 0.3% delta-9 THC.
The enactment of HB 1325 also caused an outcome that legislators did not intend. Because it changed the legal definition of marijuana from cannabis in general to cannabis containing greater than 0.3% THC, [31] many marijuana possession charges across the state were soon dropped due to a shortage of THC testing equipment available.

Marihuana prensada ('pressed marijuana') is a cannabis-derived product widespread among the lower classes of South America, [189] especially from the 90s. Locally it is known as "paraguayo" or "paragua", since its main producer is Paraguay. [190] Marijuana is dried and mixed with binding agents that make it toxic and highly harmful to health. [191]
Hashish (/ h ə ˈ ʃ iː ʃ / ⓘ; from Arabic ḥašiš 'hay'), usually abbreviated as hash, is a compressed form of resin (trichomes) derived from the marijuana flowers. [3] [4] As a psychoactive substance, it is consumed plain or mixed with tobacco.
Tetrahydrocannabinolic acid (THCA, 2-COOH-THC; conjugate base tetrahydrocannabinolate) is a precursor of tetrahydrocannabinol (THC), an active component of cannabis. [1]THCA is found in variable quantities in fresh, undried cannabis, but is progressively decarboxylated to THC with drying, and especially under intense heating such as when cannabis is smoked or cooked into cannabis edibles.
