Cough suppression
Cough suppression can be described as a decreased desire and need to cough. This can be a positive effect which either suppresses a pre-existing ailment or in certain contexts, allows an individual to inhale large amounts of smoke without having the desire to cough.
Cough suppression is most commonly induced under the influence of moderate dosages of antitussive compounds such as, codeine, pholcodine, dextromethorphan, noscapine, and butamirate. However, it may also occur under the influence of certain antihistamines such as promethazine.
