Pain relief

Pain relief can be described as an effect which suppresses negative sensations such as aches and pains. This can be done either by blocking the painful sensation from one's conscious faculties or by covering the sensation over with feelings of physical and cognitive euphoria.

Common examples of drugs which induce this effect include alcohol, opioids such as heroin, codiene or morphine and NMDA receptor antagonists such as Ketamine and MXE.
