The results of high lipid-solubility of cannabinoids is persisting in the body for a long periods of time. A single administration of THC, is detectable levels of THC which is found in the body for weeks or longer (it depends on the amount administered and on the sensitivity of assessment method). Investigators have suggested that this is an important factor in marijuana’s effects, because cannabinoids accumulate in the body, or particularly in the lipid membranes of the neurons. (Stephen, 2013)
