Exercise and fasting increases the level of tetrahydrocannabinol (THC) - the main intoxicating ingredient in cannabis - in the blood of regular cannabis users, according to new research from the University of Sydney and the University of NSW.
After abstaining from the drug overnight, researchers asked regular cannabis users to exercise at a level that would cause fat to be metabolised. The results indicated a substantial increase in blood THC as well as a jump of free fatty acids.
Because THC has a strong affinity for fat tissue, most of the ingredient consumed when cannabis is smoked is rapidly transferred from the bloodstream into fat cells, where it accumulates and can lie dormant for weeks or even months.
