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.
Ana L-pez, lead author of the study and a researcher at the University of Santiago de Compostela (USC), tells SINC that the objectives of the new study were: "To understand the factors linked to treatment outcomes, in order to help people get the right kind of treatment, reduce their chances of abandoning the treatment, ensure they stop using drugs and don't fall back into the habit".
The study, published in the Spanish journal Psicolog-a Conductual, analyses the significant factors (sociodemographic, psychopathological and patterns of drug and other substance abuse) involved in patients continuing to use cocaine two years after having requested treatment.
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.
The researchers analysed a sample of 38 people (35 men and 3 women, with an average age of 31), who sought treatment for problems related to abuse of this substance in drug treatment centres in Galicia, in northern Spain, studying them at the start of their therapy and then two years later.
