Disrupting the function of nerve cells, drugs impair or even eliminate the psychological equilibrium, the adaptability of the individual and their ability to cope with difficult intro-psychic, interpersonal or environmental situations.
Drugs affect the ability of social integration of the individual, undermining on one hand the individuals addaptive capabilities and on the other leading to a exclusion from the social fabric.The equilibrium of the social level is related to the conditions of the previous two levels, but, inturn, the level of social influence binds the pschological to the biological.
