This study was intended to investigate the nature and dynamics of drug
using behaviour in Scottish prisons. Semi-structured interviews were
carried out with a purposive sample of 234 prisoners in four major adu
lt male prisons in Scotland. Of this sample, 73% had used cannabis dur
ing their current sentence, and 95% of these reported ongoing usage. T
here was little evidence to suggest that people started to inject in p
rison. Of this sample, 32% were injecting prior to imprisonment, and 1
1% had done so during their current sentence. Of those who were inject
ing prior to imprisonment, 24% were sharing injecting equipment. Of th
ose who were injecting in prison, 76% were sharing equipment. Factors
most closely identified with current sharing of injecting equipment we
re: having injected a wider range of drugs in prison (during both curr
ent and previous sentences); frequency of Temgesic (Buprenorphine) use
; being prescribed methadone in the community, then having that prescr
iption discontinued on entry to prison. Drug use in prison should be a
ddressed within a harm reduction framework, and reduction based prescr
ibing of oral substitute drugs should be available to prisoners with d
rug problems. The basic aim of enabling people to minimise the harm wh
ich results from their drug use, thereby minimising the harm which res
ults to society, can be applied within prisons.
