[The dangers of drug career in young people]

It is significant when a young person encounters drugs for the first time. Research has shown that 70% of later addicts try the drugs during the five-year period of adolescence. Youngsters tend to try new experinces; they are high risk-takers, seek novelty and are sensitive to pressure from the peer group. However, the juvenile central nervous system reacts differently when taking drugs, than it happens in an older age. Damage could occur on critical regions of the brain. Addictive drugs may give rise to changes in multiple system of memory, that could maintain the addiction for a long time. Drug use overrides and modifies the natural reward system, induces further drug-seeking, independently from the sensations of drug use.
