Cannabis plants vary widely, with different strains producing dynamic balances of cannabinoids (THC, CBD, etc.) and yielding markedly different effects. Popular strains are often hybrids of C. sativa and C. indica. The medicinal effects of cannabis are widely studied, and are active topics of research both at universities and private research ...
Cannabis indica is an annual plant species in the family Cannabaceae [1] indigenous to the Hindu Kush mountains of Southern Asia. [2] The plant produces large amounts of tetrahydrocannabinol (THC) [3] and tetrahydrocannabivarin (THCV), with total cannabinoid levels being as high as 53.7%. [4]
For example, strains that are used as fiber (commonly called hemp) are bred such that they are low in psychoactive chemicals like THC.

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 ...
Various strains of "medical cannabis" are found to have a significant variation in the ratios of CBD-to-THC and are known to contain other non-psychotropic cannabinoids. [45] Any psychoactive cannabis, regardless of its CBD content, is derived from the flower (or bud) of the genus Cannabis .
Autoflowering cannabis or day neutral cannabis varieties automatically switch from vegetative growth to the flowering stage based on age, as opposed to the ratio of light to dark hours required with photoperiod dependent/short-day strains. Many autoflowering varieties are ready to harvest in less than 10 weeks from seed.
In addition, just this past week, the German Federal Ministry and Minister of Food and Agriculture approved the plan to allow research-focused commercial cannabis pilot programs to test legal and ...
The so-called "420 movement" is the global association of the number 420 with cannabis consumption: April 20th – fourth month, twentieth day – has become an international counterculture holiday based on the celebration and consumption of cannabis; [65] [66] [67] 4:20 pm on any day is a time to consume cannabis.
