Cocaine has become increasingly common as a social use drug and a 2nd drug of choice. It can easily become the new drug of choice, especially if consumed in the form of crack. Although it does not have the obvious and full-scale physical dependence of an opiate, alcohol or benzodiazepine, it has a severe psychological addiction that can be worse than any of those three. There are more subtle withdrawal symptoms that do exist though, that intensify the psychological addiction symptoms. These symptoms can be effectively controlled with medical treatment.
