The opioid epidemic just keeps getting worse, presenting challenges discussed at length at a White House summit last week. But opioids are not America’s only significant drug problem. Among illicit drugs, cocaine is the No. 2 killer and claims the lives of more African-Americans than heroin does.

In a recent study published in Annals of Internal Medicine, researchers from the National Cancer Institute and the National Institute on Drug Abuse found that drug-related deaths have grown across all racial groups and among both men and women. The analysis found that between 1999 and 2015, overdose deaths of any kind of drug for Americans 20 to 64 years old increased 5.5 percent per year.

For the most recent years of analysis (2012-15), the study found that deaths of men from heroin exceeded those from any other type of opioid, such as those found in pain medications. For women, deaths related to opioid medications were the most common.

But among non-Hispanic black Americans, cocaine has been a larger problem than heroin for nearly 20 years. For example, over 2012-15, cocaine overdoses claimed 7.6 per 100,000 black men. In contrast, heroin overdoses claimed 5.45 per 100,000 black men. Black women use both drugs at lower rates than men, but cocaine overdoses exceed those from heroin for them as well.
