Stimulants

Stimulants imperceptibly unless specifically observed catalyzes 'charges,' a sudden surge disturbing achieved balances and lasts until the system rebalances in the presence of the stimulant. The disturbance causing whatever effect that extra free energy and chaos thereof (as in disturbance of established patterns) makes available. Is the 'coping with uncertainty' effect at play whenever such energy chaos is introduced in whichever system, I wonder...and is that why people like to smoke, drink tea/coffee to 'awaken their brain' per se?
