Brief intervention: Patient-centered discussion that employs Motivational Interviewing concepts to raise an individual's awareness of his/her substance use and enhancing his/her motivation towards behavioral change. Brief interventions are typically performed in 3-15 minutes, and should occur in the same session as screening. The recommended behavior change is to abstain from illicit drug use.

Patients with numerous or serious negative consequences from their substance use, or patients with likely dependence who cannot or will not obtain conventional specialized treatment, should receive more numerous and intensive interventions with follow up.

Referral to specialized treatment: A proactive process that facilitates access to specialized care for individuals who have been assessed to have substance use dependence. These patients are referred to drug treatment experts for more definitive, in-depth assessment and, if warranted, treatment. The recommended behavior change is to abstain from use and accept the referral.
