Tincture of cannabis, sometimes known as green dragon, is an alcoholic cannabis concentrate.The solubility of THC in ethanol is greater than 1 g/mL. [1]According to the European Medicines Agency (EMA) cannabis tinctures (tincturea) are a type of liquid cannabis extract obtained using ethanol, water, glycerol, propylene glycol and fatty oils as extraction solvents, depending on the type of ...
THC, the main psychoactive component of cannabis, may only be detectable in saliva and oral fluid for 2–24 hours in most cases. [8] [9] The main metabolite excreted in the urine is 11-Nor-9-carboxy-THC, also known as THC-COOH. Most cannabis drug tests yield a positive result when the concentration of THC-COOH in urine exceeds 50 ng/mL. [10]
Despite the CBD and THC having the same molecular weight, multiple analytical methods are able to differentiate them. [11] "on the recovery of both THC (86.7−90.0%) and CBD (92.3−95.6%). The slightly lower recovery of THC can be explained by the fact that THC is less polar than CBD and more likely to remain in the nonpolar sunflower oil." [11]
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.
The main metabolite in urine is the ester of glucuronic acid and 11-OH-THC and free THC-COOH. In the feces, mainly 11-OH-THC was detected. [37] Estimates of the elimination half-life of THC are variable. [23] THC was reported to have a fast initial half-life of 6 minutes and a long terminal half-life of 22 hours in a population pharmacokinetic ...
CBD shares a precursor with THC and is the main cannabinoid in CBD-dominant Cannabis strains. CBD has been shown to play a role in preventing the short-term memory loss associated with THC. [29] There is tentative evidence that CBD has an anti-psychotic effect, but research in this area is limited. [30] [24]
Tinctures are potent, alcohol-based cannabis extracts. [34] The solubility of THC in ethanol is greater than 1 g/mL. [43] They are considered edibles as they are meant to be absorbed through the mouth and tongue. [34] Tinctures are generally placed under the tongue using a dropper to allow it to be absorbed into the bloodstream. [34]
Cannabis material can be leached in high-proof spirits (often grain alcohol) to create a "Green Dragon". Cannabis can also be consumed as a cannabis tea and many other beverages. Although THC is lipophilic and only slightly water soluble (with a solubility of 2.8 mg per liter), [13] enough THC can be dissolved to make a mildly psychoactive tea ...
