So, what causes heavy cannabis consumers to seem less affected by the overestimation effects of time? Could it be due to their SCN neurons getting used to the THC? Do they, therefore, stop overfire after continuous exposure? If this were to be the case, would a regular consumer of cannabis experience the same estimation of time issues if they took a tolerance pause from the herb?. Or is it just that frequent marijuana smokers get used to having to tell the time while they are stoned since it is fundamental to being a functional marijuana consumer in society?
