What causes the body to become physically dependant on drugs during drug abuse/misuse (this could be prescription medication, illegal drugs, alcohol, nicotine etc.)? What causes a person to become physically dependant on drugs and then suffer physical withdrawal symptoms after they cease taking them?
What exactly do these drugs do to the body that causes it to become dependant - a problem much more severe than psychological addiction. Psychological dependancy is caused by an addiction to the feeling the drug instigates, but physical dependancy is clearly something more complex.
Thank you
