Marijuana use among older adults has nearly doubled

As more states have legalized marijuana for recreational and medical use, the percentage of adults aged 65 and older who report using the substance has nearly doubled since 2015, according to a new analysis. Looking at data from a federal survey on drug use, researchers found that the proportion of older adults who reported using marijuana in 2015 was 2.4%, but that increased to 4.2% in 2018. The increase was more pronounced in males and in those who were non-white. The shift in marijuana use is also trending toward the more wealthy: There was a more than threefold increase among college-educated individuals as well as among those whose family income was at least $75,000. Those who had sought mental health treatment in the year prior to being surveyed as well as those who reported tobacco use in the previous year also saw big increases.

Correction: I missed an essential detail yesterday about how quickly Alzheimer's disease is growing in the U.S. New cases of the disease are growing at the rate of one per minute daily. Sorry about the confusion!
