Toledo, Ohio "Narc-Me" parties or "Lazarus Parties" are now adding another level of danger to the heroin epidemic. This is where a group of addicts decide they're going to shoot up on heroin and then someone remains sober, with the heroin anti-dote narcan standing by in case someone overdoses.
It's like playing Russian Roulette. There's no way of knowing how many doses of narcan will work if any. In addition, you have to get right to the hospital after taking narcan because it wears off quickly and could send you back into an overdose.
