Reducing Addiction Flashcards
What’s Drug Therapy?
Drugs are used to treat various addictions e.g. smoking.
Recently they’re been used to treat sex and gambling addictions.
What Drug Therapy’s Used for Nicotine Addiction?
Nicotine Replacement Therapy (NRT).
What’s the Aim of Nicotine Replacement Therapy?
To provide nicotine from a less harmful source e.g. patches, rather than a cigarette.
How Does Nicotine Replacement Therapy Work?
NRT stimulates nicotine receptors, activates brain’s reward pathway, releasing dopamine into the limbic system, stimulating the nucleus accumbens and creating the same pleasurable feeling as smoking a cigarette does.
What Does NRT Reduce?
Reduces nicotine withdrawal symptoms and stops cravings.
Reduction in wthdrawal symptoms is an example of negative reinforcement as NRT removes the unpleasant circumstances of quitting smoking.
What Does NRT Desensitise?
Desensitises the nicotine receptors in the brain, releases small amounts of nicotine so only some receptors are full of nicotine, but not all.
Over time number of nicotine receptors reduce, meaning cigarettes become less rewarding to smoke, and relapse is less likely to occur.
Addict can gradually reduce nicotine dosage as tolerance to nicotine’s reduced.
What’s the Aim of an Opioid Antagonist?
Reduces the pleasurable feeling associated with gambling.
How Do Opioid Antagonists Work?
They enhance the release of the neurotransmitter GABA in the mesolimbic pathway.
The increased GABA activity reduces the release of dopamine in the nucleus accumbens and pre-frontal cortex, making gambling less pleasurable.
AO3: Drug Therapy: Research to Support Effect of NRT
P: Stead et al.
E: Reviewed 150 high quality research studies that compared use of NRT with placebo.
E: Found all forms of NRT were significantly more effective in helping smokers quit than placebos and no treatment at all.
L: Supports drug therapy: found to be effective.
AO3: Limitation of NRT and Opioid Antagonists
P: Negative side effects.
E: Common side effects are sleep disturbance, headaches.
E: Unlike CBT, non-invasive as individual’s identifying and challenging irrational thoughts that lead to addiction.
L: Side effects cause individual to stop treatment resulting in symptom relapse, drug therapy would be ineffective as reducing individuals addiction.
AO3: Drug Therapy Strength
P: Requires little motivation from patient.
E: Because patient just has to wear a patch to reduce addiction.
E: Unlike CBT, requires more effort and motivation from patient, must commit to CBT sessions over moths, complete homework.
L: Drug therapy’s more appropriate for reducing addiction than others such as CBT.
What do Behavioural Interventions Include?
They include aversion therapy and covert sensittisation.
What do Behavioural Interventions Work On?
Both work on the principles of classical conditioning and aim to replace the pleasurable association with the addictive substance/ behaviour with an unpleasant association.
What’s the Aim of Aversion Therapy?
The idea of therapy’s to use the principles of classical conditioning to change the pleasurable association with addictive substance/ behaviour and replace it with unpleasant association in another experience.
How Does Aversion Therapy Work for Nicotine Addiction?
Specific technique is ‘rapid smoking.’
Individuals sit alone in a room taking a puff of cigarette every 6 seconds.
They begin to feel nauseous and associate this feeling to smoking.
This continues until the individual develops an aversion to smoking, reducing their addiction.
