Psychological Narcotic Withdrawal
This is the perceived need for a substance that often causes extreme anxiety, nervousness, and irritability. Although the individual feels they need the drug, their body is not physically addicted to it.

Physical withdrawal is often dramatic and serious. It can affect the cardiovascular system and the nervous system. This withdrawal may cause changes in heart rate and blood pressure.
