The National Survey on Drug Use and Health (NSDUH) also found the number of daily or near-daily users of marijuana in 2016 doubled compared to the number of heavy users about a decade ago. Use rose significantly among age groups 12 and up, 18 and up, and 26 and up. Almost twice as many 12-17-year-olds are using pot as compared to cigarettes on a past-month basis. And among those 18 and over, there has been a significant jump in the percent of marijuana users who are unemployed as compared to 2015.
