Powerful reliever for chronic pain. It's toxic and addictive.

Codeine:
Its effects are softer than morphine but is less addictive. It is used to reduce coughing.

Heroin:
Semisynthetic derivative that produces analgesia similar to morphine. It is a highly addictive drug so its use is restricted to extreme situations under medical authorization.

Papaverine:
