Sinsemilla cannabis is a cultivation technique, so it should not be confused with skunk, which refers to strains with a high percentage of THC, of up to 34% THC content. [6] The expression sinsemilla is practically obsolete since feminized seeds emerged in the 1990s, seeds genetically modified to only sprout females.
The Cannabis strains referred to in this article are primarily those varieties with recreational and medicinal use. These varieties have been cultivated to contain a high percentage of cannabinoids. Several varieties of cannabis, known as hemp, have a very low cannabinoid content, and are instead grown for their fiber and seed.
THC and its 11-OH-THC and THC-COOH metabolites can be detected and quantified in blood, urine, hair, oral fluid or sweat using a combination of immunoassay and chromatographic techniques as part of a drug use testing program or in a forensic investigation. [57] [58] [59] There is ongoing research to create devices capable of detecting THC in ...
In the US, "industrial hemp" is classified by the federal government as cannabis containing no more than 0.3% THC by dry weight. This classification was established in the 2018 Farm Bill and was refined to include hemp-sourced extracts, cannabinoids, and derivatives in the definition of hemp. [125]
The Δ 9 isomer of THCP occurs naturally in cannabis, but in small amounts.A 2021 study reported the content of Δ 9-THCP ranging from 0.0023% to 0.0136% (w/w) (approximately 0.02–0.13 mg/g) without correlation to THC percentage in Δ 9-THC-dominant strains of cannabis; that study failed to detect THCP in CBD-dominant strains.
Marijuana use in the United States is three times above the global average, but in line with other Western democracies. Forty-four percent of American 12th graders have tried the drug at least once, and the typical age of first-use is 16, similar to the typical age of first-use for alcohol but lower than the first-use age for other illicit drugs.
Cannabis ruderalis has naturally low concentrations of THC. With hybrid breeding, autoflowering plants can contain levels of THC similar to the strain they're bred with. [13] [2] [14] Breeders have reported THC content around 25% in some newer varieties while many varieties also have high CBD content. [15] [16] Some advantages of autoflower ...
The phrase entourage effect was introduced in 1999. [9] [10] While originally identified as a novel method of endocannabinoid regulation by which multiple endogenous chemical species display a cooperative effect in eliciting a cellular response, the term has evolved to describe the polypharmacy effects of combined cannabis phytochemicals or whole plant extracts.
