The devastation wrought by opioids in recent years is only part of a much larger drug crisis in the United States that stretches back four decades, according to a new study published Thursday in Science.

A commonly used painkiller might be too risky for people to keep taking, suggests a new study published this week in the BMJ.

There’s evidence of a connection between cannabis use and schizophrenia, but it’s unclear whether the drug leads to the disorder, or vice versa. A new study published Monday, which relies partly on genetic data from 23andMe volunteers, might offer a little clarity on that link. It found that people genetically at…

In what might be one of the least shocking revelations ever, the authors of two recently published papers accuse tobacco companies of further dishonesty (you know, besides decades-long attempts to downplay the addictiveness of cigarettes).

You don’t have to go far to find people, including doctors and researchers, who will argue that a little bit of alcohol can actually help you live a longer, healthier life.

A life-saving but increasingly expensive treatment for severe allergic attacks is poised to become cheaper.

Not everyone who is close to death—or thinks they are, at least—has a “near-death experience.” But those who do often hallucinate that they leave their bodies, meet otherworldly beings, see bright flashes and tunnels of light, and more. Those who take the psychedelic drug dimethyltryptamine, or DMT— a compound found…

Synthetic cannabinoids are behind yet another mass overdose in the U.S. More than 70 people in New Haven, Connecticut suffered overdoses thought to be caused by the lab-made drug known as K2 within the span of a day, NBC Connecticut reported Wednesday.

The devastating story of thalidomide—a once-popular morning sickness drug later found to cause terrible birth defects—might have a few more chapters left to it.
