What is contingency management and for which substances has it shown robust efficacy?

• A. A behavioral program providing tangible rewards for verified abstinence; effective for stimulant (cocaine, methamphetamine) use and also opioid and nicotine.
• B. A pharmacological treatment that blocks dopamine.
• C. A family therapy approach with no measurable outcomes.
• D. A medical device.

Answer: (A)

Contingency management is a behavioral approach that uses tangible rewards to reinforce abstinence. In practice, individuals earn incentives (like vouchers or prizes) when objective tests show they have stayed abstinent, with frequent monitoring through urine drug screens or other biological tests. This immediate, verifiable reinforcement strengthens abstinent behavior by tying it to positive outcomes, aligning with principles of operant conditioning.

This method has shown robust efficacy for stimulant use disorders, notably cocaine and methamphetamine. It also has solid evidence supporting its use with opioid use disorders (especially when combined with medication-assisted treatment) and for nicotine cessation, where incentives help people quit smoking. In short, contingency management uses concrete rewards for verified abstinence and is particularly effective for stimulant problems, with strong or growing support for opioids and nicotine as well.
