No, some local governments have been doing
safe injection sites. Safe supply is a political football that's scapegoated despite not being implemented anywhere in Canada. And neither is a solution to the homelessness, addictions, and mental health crises.
Every time I hear a politician talking about safe supply, they say it's not a silver bullet. Which is weird because nobody claims it's a silver bullet. Know what else isn't a silver bullet? Criminalization. Or, everything else that's ever been tried. It's a hard problem, there isn't a silver bullet solution, get over it.
What's harm reduction good for? Reducing harm. It isn't harm prevention, it isn't free housing, it isn't free addiction counseling, it doesn't fart roses.
Safe injection sites keep users close to medical professionals so we can keep people from dying alone. Safe supply would ensure that users aren't going to accidentally OD on kerfentanyl thinking it's ordinary fentanyl. Needle exchanges keep users supplied with sterile equipment to reduce risk of injections such as HIV and hepatitis C. Each policy is an example of harm reduction. The general philosophy is to not let perfect be the enemy of good.
