Recreational Recreationally speaking,<unk> s are used to change one’s state of mind and users report feeling a "rush" as the central nervous system is flooded with dopamine and epinephrine, and norepinephrine. This rush is caused by the sudden change in both the electrical and chemical activity in the brain.
