And this would prevent overdoses how?
Because the opioids are unregulated due to them being illegal there is no quality control.
"Many family members and peers of those who have died are working hard to prevent more deaths, and as a health authority we must do the same. We must learn from the circumstances surrounding each death, to address the underlying causes and address gaps in our response to date. This is the primary goal of this report. T
he evidence presented here indicates that replacing the unregulated, illegal supply of opioids with legal alternatives must rise to the top of our priority list, and requires our urgent attention."

"Drug checking is a harm reduction service that provides clients with valuable information about the composition of their drugs, including whether they are likely to contain potent opioids, such as fentanyl. Drug checking can also provide useful information about the presence of other substances, like synthetic cannabinoids, metformin, detergent, and plaster, that can cause harm to people who unknowingly ingest them. When these substances are found in the drug supply and reported to VCH’s RADAR system, alerts can be sent out to the community. Drug checking is currently offered at supervised consumption sites, overdose prevention sites, and as part of housing overdose prevention services"
