The number of children (ages 3 to 11 years) in the United States who are exposed to tobacco smoke has decreased steadily from 1999 to 2014. However, childhood tobacco smoke exposure differs among sociodemographic groups.
The spread of marijuana use and the opioid epidemic over the past 10 years have affected middle-aged and older Americans. In addition, prescription opioid and benzodiazepine misuse increased older adults’ risk of suicidal thoughts.
Researchers used the statistical technique of latent class analysis to describe distinct patterns of marijuana use across age using data from nearly 10,000 participants in the Monitoring the Future study. Longer-term marijuana use (extending from age 18 into the late 20s or beyond) was associated with increased risk of self-reported health problems at age 50.
