In Canada, restrictions on BUP-NX prescribing were relaxed in 2016, which may have had an effect on rates of diversion and non-prescribed use. We sought to longitudinally examine the reported availability and use of non-prescribed BUP-NX among people who use drugs (PWUD) in an urban Canadian setting.
We observed that BUP-NX has become increasingly available in the unregulated drug supply in recent years but its use has remained infrequent in this setting. These results suggest that relaxed restrictions on BUP-NX prescribing have not been a major driver of increased non-prescribed use in this population.
