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 20% THC levels. Volatile solvents, such as ethanol , butane , propane or hexane , may be used to prepare extracts, but can and will possibly lead to fire and explosion hazards ...
Polyvinylpyrrolidone (PVP), also commonly called polyvidone or povidone, is a water-soluble polymer compound made from the monomer N-vinylpyrrolidone. [1] PVP is available in a range of molecular weights and related viscosities, and can be selected according to the desired application properties.
The most common quality indicator is the smell. High-quality hash will smell fragrant and aromatic, whereas hash of low quality may have a distinct mouldy or musty aroma. [35] The tetrahydrocannabinol (THC) content of hashish comes in wide ranges from almost none to 65% and that of hash oil from 30% to 90%. [36]
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]
α-Pyrrolidinopentiophenone (α-PVP), also known as α-pyrrolidinovalerophenone, O-2387, β-keto-prolintane, prolintanone, [2] [3] or desmethylpyrovalerone, is a synthetic stimulant of the cathinone class developed in the 1960s that has been sold as a designer drug and often consumed for recreational reasons.
4-Chloro-α-pyrrolidinovalerophenone (also known as 4-chloro-α-pyrrolidinopentiophenone, 4-chloro-α-PVP, 4Cl-PVP, or 4C-PVP, or alpha-PVP, or flakka) is an emerging recreational designer drug of the pyrrolidinophenone class, similar in structure to α-pyrrolidinopentiophenone (α-PVP). [1]
3-Fluoro-α-Pyrrolidinovalerophenone (3F-PVP) is a recreational designer drug from the substituted cathinone family with stimulant effects, which first appeared on the illicit market in around 2018. [ 1 ] [ 2 ] It is illegal in Finland.
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.
