  • When possible, make sure to use in a safe area with people you can trust.

Please continue to use the precautions outlined below to reduce your risk of overdose.

Reduce your risk

  • Carry naloxone
  • Never use alone. However, it is important to maintain 2 metres distance to protect yourself during the COVID-19 pandemic. Phone a friend or call the Overdose Prevention Line (1-888-853-8542) to make sure someone is available to check up on you.
  • Start low and go slow (e.g., with every new purchase, start with 1/3 of a normal dose)
  • Use the Consumption and Treatment Services Site (CTS) supervised by health professionals at Guelph’s Community Health Centre located at 176 Wyndham St. N

Get a naloxone kit

You can get a take-home naloxone kit for free from pharmacies and other agencies in the Wellington-Dufferin-Guelph area. A health card is only needed if you are receiving a kit from a pharmacy. Pharmacies offer injectable naloxone only, where other sites offer nasal naloxone. Visit for a list of locations to get a naloxone kit.
