Citing an “unusual rise in heroin overdose deaths,” King County Health issued a bulletin Tuesday night warning of possible increased potency of the drug and the risks of mixing it with other drugs and substances. 

KING COUNTY, WA—Since Saturday, the King County Medical Examiner’s Office has identified seven likely overdose deaths from heroin, possibly due to an increased potency of the drug or mixture with other substances. This is a notable and rapid rise in deaths; King County saw 32 heroin overdose deaths in total over the first six months of 2011.

CHS reported on two overdoses within one block of Summit Ave and 30 minutes of each other early Monday morning. We have been told that one of the people in those incidents, a woman in her 40s, died at the scene. A man in his 30s from the second incident was taken to the hospital after undergoing CPR at the nearby scene. We do not have information on his condition.

The county alert says that the victims in the spike of overdoses have ranged in age from 17 to 61 and warns against mixing the drug with “benzodiazepines (i.e. benzos), alcohol or prescription-type opiates such as OxyContin or methadone” or “stimulants such as cocaine or methamphetamine.” The full alert is below.

KING COUNTY, WA—Since Saturday, the King County Medical Examiner’s Office has identified seven likely overdose deaths from heroin, possibly due to an increased potency of the drug or mixture with other substances. This is a notable and rapid rise in deaths; King County saw 32 heroin overdose deaths in total over the first six months of 2011.

Because of this sudden increase in deaths, health officials are issuing a public alert about the overdose danger. We are working with partners to analyze the heroin and identify possible reasons for the sudden increase in deaths.

“The best way for injection drug users to prevent overdose is not to use heroin, but for those who do, they need to be aware of the overdose risks,” said Dr. Charissa Fotinos, Medical Director for Public Health — Seattle & King County.

Key ways to reduce the risk of overdose include:

Never inject when you’re alone
If you got heroin from someone new or it looks different, use less.
Don’t use heroin in combination with other “downers” such as benzodiazepines (i.e. benzos), alcohol or prescription-type opiates such as OxyContin or methadone. It is also dangerous to use with stimulants such as cocaine or methamphetamine.
The seven who likely died from overdose were from areas across King County, ranged in age from 17-61 years of age, and included both experienced and inexperienced users.

If someone is with a person who is overdosing on heroin, they can help by immediately calling 911. The Washington state Good Samaritan law took effect in 2010 and provides immunity from criminal charges of drug possession for both the witness and the person experiencing the overdose.

The new law also expands access to Narcan (generic name naloxone), an opiate antagonist that reverses the effect of overdose from heroin and other opiates. Public Health – Seattle & King County has recently initiated a Narcan program at its Downtown Seattle needle exchange to dispense Narcan to heroin users and train them on how to use it in an emergency.

Public Health is also working with community partners to alert members of the public who use heroin that there appears to be an increased risk of death from using heroin currently being sold.
