"Perception of time-intervals is believed to be mediated by spiny neurons located in the striatum of the basal ganglia. Timing begins with a burst of dopamine and ends with a recognized signal. Marijuana slows subjective time by lowering dopamine available, whereas cocaine and methamphetamine accelerates the sense of time by increasing dopamine availability. (Adrenaline and stress hormones can also "make seconds feel like hours".)" Tweet
