Cough suppression
Cough suppression is a common effect which can be described as a decrease in the desire to cough. This can be a positive effect which either suppresses a pre-existing cough or allows an individual to inhale large amounts of smoke without having the desire to cough. This effect commonly can occur on DXM, opioids such as codeine, and anticholinergics such as promethazine.
