Answer:
True.
Explanation:
Considered a mental disorder, in addition to a social problem by the World Health Organization (WHO), chemical dependence is considered a chronic disease, which commonly affects individuals who make constant use of certain drugs. The bearer of this type of disorder is unable to contain the addiction, affecting their psychic, emotional, physical life and, consequently, social life.
Chemical dependence manifests itself in the body and psychological dependence is characterized by the need for the drug to obtain pleasure or emotional comfort. The DSM (Diagnostic and Statistical Manual of Mental Disorders) considers chemical dependence a disease and characterizes it as biopsychosocial because it presents a grouping of cognitive, behavioral and physiological symptoms of wide and varied aspects.
Accordingly, we can say that, it is true, the requirement to have to take more of the drug to get high is a psychological or emotional sign of addiction.
