Researchers have found that 90% of older people addicted to drugs or alcohol developed his or her dependence whilst they were still inside of secondary school. An additional surprising point is usually that 75% of students in the US have used tobacco, drugs and alcohol. And that 20% of them are actually hooked. Probably the most abused drug in adolescent school students is actually alcohol. Using tobacco will come in next, with marijuana and pharmaceuticals. The prescribed medication substance abuse will involve narcotic painkillers plus drugs prescribed for attention deficit disorder. The more youthful the child is when they begin to abuse addicting chemicals, the better the chance that they can grow to be addicted. Adolescents will be risk takers and can often be at risk to using addicting substances because the part of the human mind that controls impulse and common sense isn’t totally evolved.
