Young adults are now more than twice as likely to smoke marijuana compared to cigarettes, according to a new analysis of Gallup survey data. the percentage of adults aged 18-29 who smoked in the past week has fallen from 15 percent in 2016-2018 to a new low of 12 percent in 2019-2022. At the same time, 26 percent of adults in this age group now say they smoke marijuana, compared to 21 percent during the earlier survey period. Overall, the 2019-2022 data show that 27 percent of Americans smoke cigarettes, marijuana or e-cigarettes. Gallup found that 7 percent smoke only marijuana, 9 percent smoke only cigarettes and 3 percent smoke only e-cigarettes. But the youngest generation is most strongly choosing marijuana over cigarettes - a trend that can be attributed to many factors, including public education campaigns about the dangers of tobacco and declining public awareness of the dangers of marijuana.
