Because more of these neurotransmitters remain active in the brain, the result is an increase in the activity of the sympathetic division of the autonomic nervous system (ANS).

Levels of some of the brains chemical messengers, or neurotransmitters, are also impacted by drug abuse, including: Regions of the brain are disrupted by drug abuse, as the National Institute on Drug Abuse (NIDA) reports that the brain stem, limbic system, and cerebral cortex are all affected. One such part of the brain, the hippocampus, manages short-term memory, meaning that marijuana use can impede recollection of recent events. These slow down the central nervous system, having an impact on both mental and physical activity. Because they cause a persons breathing to slow, misusing them can cause hypoxia, when the brain does not get enough oxygen. They range from heroin to caffeine.
