Joseph Deane had been drug free for months before he overdosed in the bathroom of a restaurant in New Haven last December. He couldn’t resist when his dealer offered drugs. Unfortunately, the dope turned out to be fentanyl. Deane, just 23 years old, had been fighting addiction for years, but fentanyl, a synthetic opioid, took his life because it’s 50 to 100 times more powerful than heroin. After months without drugs, his body couldn’t handle it.
