People commonly think of opiates, such as morphine
, or semi-synthetic opioids derived from opiates, such as oxycodone
, when they think of drug dependence or addiction. But as anyone who drinks three cups of coffee a day is bound to realize, the body can become dependent on far less damaging substances, as well. Many people using drugs to manage their pain are dependent on those drugs without being addicted to them. They take the drugs to function normally and live productive lives.
