Conclusion
high monitored heroin maintenance programmes are effective at reducing cocaine use
6 of 12
Generalisability
large sample but only generalisable to heavily dependent, quite long term users
7 of 12
Reliability
self report data validated with urine tests. cause and effect hard to pinpoint because other factors could have impacted the results such as the help received from counselling
8 of 12
Applicability
applied to helping poly drug use solely one drug (heroin in this case) before moving on to other treatments that can target individual drugs
9 of 12
Validity
already on drug treatment programme so natural task. all the attention that they received from the study may have impacted their behaviour e.g. stopped taking cocaine because felt so many people were believing in them.
