Police have decided to continue a scheme giving out DIY drug kits in a bid to rid the city of dirty needles. The project involves handing out clean needles to addicts, who are also given sharps bins to dispose of them safely but there are complaints that the bins are too big.

Quite right too. If a sharps bin is to be used it must be an appropriate size for its purpose.  For addicts, small sharps bins might encourage proper use. If provided with an over-sized bin, it will sit at home largely unused. But then, too small and the overflow must somehow be accommodated.

The same is true of those receiving self-injected therapies. Too often sharps disposal for these therapies is completely overlooked, or perhaps patients will get only a bin that is available off-the-shelf at outpatients. In that case, it will be far too big, and for some can have an adverse psychological impact too. That is a complex matter discussed elsewhere.

Size dictates the need for collection and disposal. Small sharps containers fill quickly and must be replaced more often. Providing sharps containers without planning for their collection and timely replacement if a common failure in community care, including n doubt this particular initiative with IV drug users.
