This brief questionnaire is about alcohol, tobacco products and other drugs. We will ask you some questions about your experience of using these substances across your lifetime and in the past three months.

These substances can be smoked, swallowed, snorted, inhaled, injected or taken in the form of pills.

Some of the substances listed may be prescribed by a doctor (like amphetamines, sedatives, or pain medications). If you have only taken such medications as prescribed by your doctor, say "no" when asked if you have used them.

However, if you have ever taken such medications for reasons other than prescription, or taken them more frequently or at higher doses than prescribed, you should say "yes".

Even though you will be asked about your use of various illicit drugs, rest assured that your answers are completely anonymous and confidential.
