Long lasting effects of chronic heavy cannabis abuse. ncbi, chronic, impaired, delusions, Long-term, Studies, Research

The existence of hallucinations, delusions, and organic brain dysfunction in heavy cannabis users seems to be associated with cannabinoid levels in hair. The continuation of persistent symptoms 3 months after the discontinuation of cannabis abuse, was a remarkable finding. SCIENTIFIC SIGNIFICANCE: We provide evidence that chronic and heavy cannabis abuse results in long-lasting brain dysfunction in all users and in long-lasting schizophrenia-like psychotic symptoms in more than half of all users. These findings suggest a reevaluation of the current classification of cannabis as a "soft narcotic" which erroneously, therefore, is typically considered harmless. (Am J Addict 2017;XX:1-8).

Why Is It So Hard To Test Whether Drivers Are Stoned? Potency, impaired, drugged driving, DUI

The simple fact that THC is fat soluble. That makes it absorbed in a very different way and much more difficult to relate behavior to, say, [blood] levels of THC or develop a breathalyzer."  The height of your intoxication isn't at the moment when blood THC levels peak, and the high doesn't rise and fall uniformly based on how much THC leaves and enters your bodily fluids, says Marilyn Huestis, who headed the chemistry and drug metabolism section at the National Institute on Drug Abuse.

The Futile Search for the “Right” THC per se Level alcohol, driving, impaired

THC is a large, fat-soluble molecule whose concentration in the blood rapidly drops as it is sequestered into the body’s fat stores, including the brain.  Immediately after smoking a joint, the THC level will be very high in the blood and very low in the brain.  The THC level in the brain climbs rapidly at the same time that as it is declining in the blood.  At some point, the concentrations cross, and the concentration continues to rise in the brain while it is still declining in the blood, since the brain acts like a sponge, soaking up the partially insoluble THC from the blood.

What level of THC in blood causes driving impairment? driving, impaired, drug testing

Let us provide a rational answer to a nonsensical question. It is a nonsensical question because blood is never impaired by THC. Never. Alcohol doesn’t impair blood either. These drugs only impair the brain, not the blood.
