The drug dependence It implies certain behaviors that generate physical, psychological and social deterioration. The addict, for example, wishes to reduce or suspend the consumption But he can't do it. On the contrary, it is common for the amount consumed to grow every day since the level of tolerance of the organism is increased (and, therefore, to achieve the desired effects, the dose must be increased).
The drug addict also tends to gradually abandon his usual social relationships and reduce daily activities, since the intake of the drug occupies his time and interest. In the event that, for one reason or another, suspend consumption, the abstinence syndrome (a physical and psychological reaction to the lack of drugs).

However, they will then have to deal with adverse aspects such as insensitivity, memory loss, social isolation or various sleep problems.
Amphetamines, inhalants, opiates or angel dust are other substances that create drug addiction. A problem is that in order to overcome it requires that the person who suffers it be put in the hands of experts because only in that way can he leave the well in which he is.
