Psychotropic drugs are medications that alter mood, perceptions, and behavior. 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.

A multilevel analysis. While depressants are the drugs which slow down the nervous system, stimulants are the ones which stimulate the central nervous system and speed up the messaging process.
