Because of advances in technology, it's easier for teens in Texas and elsewhere in the country seeking controlled substances to find ways to do so. While marijuana and alcohol are still the main substances illegally obtained by teens, some young people within this age group are also experimenting with prescription drugs, potent narcotics, and various street drugs. Teens typically obtain drugs by pooling their money together, getting them from a friend who has access to drugs, or stealing prescription drugs from medicine cabinets at home.
