But in comparison to a physical location, outreach teams are limited in the resources they can offer, says Mia Hershkowitz, a harm reduction worker. For instance: Hershkowitz describes how outreach teams can only carry small amounts of oxygen due to its weight. But as terrifying amounts of veterinary tranquilizer poison the unregulated supply of drugs, Naloxone, the medication commonly used to reverse opioid poisoning, is simply not strong enough. People who are overdosing often need oxygen to help bring their heart rate back up – but outreach teams rarely have access to it.
