Drug dependency is a recurrent but treatable kind of addiction. However, not all people who are drug dependent progress in the same way once they stop taking drugs. A new study shows that, in the case of cocaine, a high score on the so-called ‘scale of craving’, an antisocial personality type and previous heroin abuse are the factors most commonly involved in people falling back into the habit.
A high score on the ‘scale of craving’ (which measures the level of anxiety or desire to take drugs) at the start of the treatment, an antisocial personality type, and having previously taken heroin at some point previously in life are the main factors involved in falling back into cocaine abuse. For this reason, “it is crucial to first evaluate the person’s consumption history and personality type,” explains the researcher.
