Drug Use Check

Here you will find two screening tools - one for youth under the age of 19 and one for young adults 19 or older.

These screening tools are designed to help identify problems with drug use. They do not consider all possible problems associated with drug use. These tools are not designed to provide a diagnosis. Only a professional can make a diagnosis. This screening is not perfect, and we advise you to take action if you are distressed and want to seek help, even if you score in the low range of severity. 

The youth screening tool includes questions about both drug and alcohol use - over the past month.

The young adult screening tool consists of questions that ask about your potential involvement with drugs - not including alcohol - during the past 12 months. (If you are 19 or older and would like to learn about your alcohol use, please take the Alcohol Use Check Quiz.)  For the purpose of this screening tool, drug abuse refers to: the use of prescribed or "over the counter" drugs in excess of the directions and any non-medical use of drugs. The various classes of drugs may include: cannabis (e.g. marijuana, hash), solvents, tranquilizers (e.g. Valium), barbiturates, cocaine or crack, stimulants (e.g. meth, speed, Ritalin), hallucinogens (e.g. LSD) or narcotics (e.g. heroin). 

If you have difficulty answering any of the questions, choose the response that is mostly right.

We will not share your answers or any information about you with anyone. Please see our privacy policy for more information.
