Nothing PnP-specific, but here’s some good harm reduction sites:
AIDS Programs South Saskatchewan
“Reduce the Harm," Peer Support Group is a safe and supportive place for people to discuss substance use regardless of their goals around use or how they choose to define their relationship with substances.
