Not certain, but maybe search for any local outreach centres that deal with drug use and rehab. Even if they won't take them they might be able to direct you. Keeping needles off the streets is a public health thing so there are probably official spots for safe disposal. My wife is in healthcare so she just brings ours in to work every couple of weeks and adds them to their bigger containers.
Morning everyone in the UK. I have all the supplies and just mixed my first vial. One thing I still can't find an answer for though. Is there an official way here to get rid of a full sharps bin? I searched online and couldn't find any service, so I'm wondering what others do.
