Researchers may be one step closer to developing the equivalent of a Breathalyzer for detecting marijuana use.
In an early study, scientists found that their rapid test was able to reliably detect THC in people's saliva in under 5 minutes. THC, short for tetrahydrocannabinol, is the active ingredient in marijuana.
Right now, the "gold standard" for detecting marijuana use is to meas...

The coronavirus pandemic has posed significant challenges for many, but it did not appear to drive U.S. preteens and young teens to drugs.

As legal use of marijuana expands, experts say U.S. cancer patients are still far less likely to use it than the general population.
That's the key finding from a new study based on data on smoking habits -- both tobacco and pot -- collected from nearly 20,000 people between 2013 and 2018. Several U.S. states legalized recreational pot during that time.

Smoking pot appears to affect teens' brain development, altering it in ways that could diminish their reasoning, decision-making and memory skills as they age, a new study reports.

Combining drugs with driving is a potentially deadly but all too common combination in the United States, according to a new report.

People using cannabis for pain may still be taking opioid painkillers, a new study suggests.
