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 ...
The alcohols extract undesirable water-soluble substances such as chlorophyll and sugars (which can be removed later by washing with water). Non-polar solvents such as benzene, chloroform and petroleum ether will not extract the water-soluble constituents of marijuana or hashish while still producing hash oil. In general, non-polar cannabis ...
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 ...
Based on the results of 3 high quality trials and 5 of lower quality, oral cannabis extract was rated as effective, and THC as probably effective, for improving people's subjective experience of spasticity. Oral cannabis extract and THC both were rated as possibly effective for improving objective measures of spasticity. [73] [74]
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. [55] 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]
Cannabinoids, including tetrahydrocannabinol (THC), the active drug in cannabis, can also be produced by bioengineered yeast, a process colloquially known as pharming. [1] In 2007, a research group reported the successful transgenic placement of a THCA synthase gene from Cannabis plant into the Pichia pastoris yeast, giving the yeast the ability to turn the precursor molecule cannabigerolic ...
CBN was the first cannabis compound to be isolated from cannabis extract in the late 1800s. Its structure and chemical synthesis were achieved by 1940 [34], followed by some of the first pre-clinical research studies to determine the effects of individual cannabis-derived compounds in vivo. [35]
Making charas from fresh cannabis resin, Uttarakhand, India. The sticky resins of the fresh flowering female cannabis plant are collected. Traditionally this was, and still is, done in remote locations by pressing or rubbing the flowering plant between two hands and then forming the sticky resins into a small ball of hashish called charas. This ...
