Opioid Surveillance and Monitoring


March 2017: Public Health Services has been notified of reports of a drug called “takeover” or "dirty fentanyl" which is crack laced with fentanyl. Reports are that this drug is causing an immediate and dangerous loss of consciousness. 

December 2016: Be aware that street drugs in Hamilton may contain a deadly opioid drug carfentanil. It is 100 times more toxic than fentanyl and is hidden in other drugs. It will cause more overdoses and deaths.

There is no easy way to know whats in your drugs. You can't see it, smell it or taste it. Substances such as fentanyl and carfentanil can be cut (mixed) with other drugs. Even a very small amount can cause an overdose.

An opioid overdose is a medical emergency. Prevent opioid overdose death and save lives using the 4 C’s of safety:

  • Careful Use - Don’t use alone, go slow by testing the effect with small amounts first
  • Carry naloxone - Get a FREE naloxone kit, and training at the following locations:
    • City of Hamilton Public Health Services Harm Reduction program: 905-546-4276
    • Participating local pharmacies by calling the Drug and Alcohol Helpline: 1-800-565-8603
  • Call 9-1-1 for every overdose. You, your friend or family member needs hospital care to survive.
  • CPR. Push Hard, Push Fast
