The opioids activate the sympathetic division of the ANS, causing blood pressure and heart rate to increase, often to dangerous levels that can lead to heart attack or stroke. This means that they speed up the central nervous system, increasing heart rate, body temperature, and blood pressure while increasing energy levels, focus, attention, alertness, and wakefulness.

(2007). Impaired coordination, learning issues, and sleep problems can result from long-term marijuana use and its impact on the brain.
