What do we really mean by “drug use” or a “drug problem”?
It’s imperative to always collect DATA
avoid meaningless statements like “(s)he uses drugs”
Who gets into more harms (gets into more trouble) from binge drinking – males or females?
Risk Factors include:
Community, parental, and peer attitudes and behaviours
Poor school performance
Earlylife stressors (selfmedicate) (e.g., “rat parks”)
Acute (current) stressors (selfmedicate)
Mental illnesses (selfmedicate)
Desire to have fun
Protective factors include:

still not labeled “causes”
examples of antecedents:
poor academic performance
attachment to a drugusing peer group
parental and community norms that support drug use
A gateway substance is: A substance that, if used by a younger person, increases the likelihood of other drugs being used when the
person is older
A substance that if used by a person of any age, increases the likelihood of the use of other drugs (usually
the later use of “hard” drugs)
The use of which drug best predicts subsequent “hard drug” use?
Why take drugs?

Driving too fast
Drinking too much
Societal, community, and family factors play an important role in whether an individual tries a drug
