The researchers played a dirty trick on some male fruit flies, housing them with
other males that had been genetically altered to exude female pheromones, or
scent molecules.
Marijuana has relatively higher concentrations of cannabinoids, terpenes and
other molecules leading to its intense
scent and coloring, and these constituents interact with the human body through the endocannabinoid system, which then interacts with
other physiological systems.
