Q

What does methadone do to the body?

A

Replaces heroin at the synapses which allows the drug user to function normally and reduces withdrawal symptoms

Q

Why is psychology in society a strength of methadone as a treatment for heroin addiction?

A

Understanding important of methadone treatment leads to greater knowledge in terms of helping addicts to recover

Q

Why is nature-nurture a strength of methadone as a treatment for heroin addiction?

A

Main strength of opiate substitution treatments like methadone is that it can help address some of the social influences of drugs, including reducing the need for a person to approach a drug dealer and their exposure to drugs

Furthermore, if a person isn’t spending time with other people who share drug-taking attitudes this can have positive effect on external influences

Q

Why is Hasan et al (2014) refuting evidence of methadone as a treatment for heroin addiction?

A

Hasan found that combining opiate substitution treatments with psychosocial support increases likelihood that a person will not return to drug use

Can be argued that psychological treatment allows the person to address underlying motivation for drug use which methadone alone doesn’t tackle

17
Q

Why is time-consuming a weakness of methadone as a treatment for heroin addiction?

A

Opiate substitution treatments can take months and therefore require a person to continue to engage with the programme for a long period of time

If individual chooses not to carry on with treatment, it makes it likely that they will return to drugs as they will still have feelings of dependency and addiction

18
Q

Why is ethical issues a weakness of methadone as a treatment for heroin addiction?

A

Some argue methadone is simply replacing one drug with another, without addressing the reasons why the person started using heroin in the first place

This can leave people vulnerable to start using drugs again, if reason for initial use isn’t addressed in addition to physical addiction

19
Q

Why is social control a weakness of methadone as a treatment for heroin addiction?

A

May be issues of social control surrounding the inappropriate prescribing of medication

Most GPs prescribe methadone as a routine treatment for heroin addicts, but may not be the best choice

Addict may be perceived as having a choice about taking their methadone, but is unlikely to go against their GPs advice
