Treating addiction: drug treatments (such as aversion therapy and substitute drugs) and behavioural and cognitive approaches based on the learning theory, with an evaluation of each.

What this dot point is asking

Edexcel wants you to describe and evaluate treatments for addiction: drug treatments (such as aversion therapy using a drug, and substitute drugs) and behavioural and cognitive approaches based on the learning theory. Link each treatment to its underlying explanation and weigh strengths and weaknesses, including ethical concerns.

Drug treatments

Evaluation of drugs. Strengths: they can reduce cravings and withdrawal quickly with little effort, helping a person stabilise. Weaknesses: they may not address the psychological causes, can have side effects, and dependence can simply shift to the substitute. Aversion therapy also raises ethical concerns because it deliberately causes discomfort.

Behavioural and cognitive treatments

These follow from the learning theory: if addiction is learned, it can be unlearned or managed.

Aversion therapy (above) is itself a behavioural treatment, using classical conditioning to break the positive association with the substance.

Cognitive behavioural therapy (CBT) helps the person identify the triggers and thoughts that lead to the addictive behaviour, challenge unhelpful beliefs (for example "I can't cope without it"), and learn coping strategies to handle cravings and high-risk situations without relapsing. It targets both the conditioning (cues) and the thinking.

Evaluation. Strengths: these treatments address the cause and triggers, and CBT gives lasting coping skills that reduce relapse. Weaknesses: aversion therapy can be unpleasant and ethically questionable, effects may not transfer to real life outside the clinic, and success depends heavily on the person's motivation.

Combining treatments

Because each approach has different strengths, the most effective programmes often combine them: drugs (such as substitutes) manage the withdrawal and cravings so the person can function, while CBT changes the learned behaviour and thinking to prevent relapse. The right mix depends on the type and severity of the addiction and the person's circumstances.

Try this

Q1. What type of conditioning is aversion therapy based on? [1 mark]

• Cue. Classical conditioning (pairing the substance with an unpleasant reaction).

Q2. Give one example of a substitute drug treatment. [1 mark]

• Cue. Nicotine replacement (patches or gum) for smoking.

Q3. Explain one strength of CBT for treating addiction. [2 marks]

• Cue. It addresses the triggers and thoughts behind the addiction and teaches lasting coping skills, reducing relapse.
