This is the favorite drug of abuse by young people and may lead to more dangerous drug abuse. Most do not show up in a routine drug screen and are called:

A. inhalants: Inhalants (glue, paint thinner, etc.) are often abused by young people due to easy access. They rarely show up on standard drug screens and are linked to progression to other substance use. B. stimulants: Includes drugs like amphetamines or cocaine, but these typically appear on drug screens and are not as common among young adolescents as inhalants. C. depressants: Includes benzodiazepines and barbiturates; these are controlled substances and more common in adults or polydrug users. D. hallucinogens: Not typically the entry point for adolescent drug use, and many (like LSD) can be detected with specific screens.
