Substance abuse is also know as drug abuse.
This is not limited to mood altering or psycho-active drugs. When an activity is performed using objects against the rules or policies - as in steroids for sports - it may be called "substance abuse."
Mood altering and psychoactive substances are therefore not the only types of abuse. Consumption of illicit drugs, stimulants, depressants, even glues and paints can fit into the category of drug abuse.
At Becker Psychological Services we provide evaluation and treatment of poly-substance abuse.
