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 catchphrases promoting legal weed include "the good stuff" and "quality you can trust." The belief that any cannabis product carrying a certificate of analysis, or COA, is safe is foundational ...
Prior to the outbreak, vitamin E acetate was used in concentrations under 20% of the formula in vape cartridges, as a thickening agent. [19] As a result of a limited availability of cannabis in California, as well as high demand, illicit sellers used 50% or higher concentrations of diluent thickeners to add bulk to low potency cartridges.

There is a slight increase in dose proportionality in terms of peak and area-under-the-curve levels of THC with increasing oral doses over a range of 2.5 to 10 mg. [21] A high-fat meal delays time to peak concentrations of oral THC by 4 hours on average and increases area-under-the-curve exposure by 2.9-fold, but peak concentrations are not ...
A survey of American adults found that many erroneously believe it is safer for the lungs to smoke weed than tobacco, and that any secondhand smoke from marijuana is also safer.
Cannabis flower is commonly consumed using a dry herb vaporizer. The cannabis may be heated in a chamber via indirect flame exposure or an electrical heating element, allowing users to inhale the resulting vapor. The temperatures reached are cooler than the combustion temperature of cannabis, which is around 230–315 °C (445–600 °F). [9]
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]
The FBI concluded in a 2012 memo that as a result of the publication of J.W. Huffman's research, people searching for a "marijuana-like-high" would follow his recipes and methods. [ 5 ] Eicosanoid synthetic cannabinoids are analogs of endocannabinoids , such as anandamide .
