if it keeps going this way, it should be legal in our generation Middle-aged parents are now more likely to smoke weed than their teenaged kids new federal data show a stunning reversal of that age-old stereotype. Middle-aged Americans are now slightly more likely to use marijuana than their teenage children. The research, released this week by the Centers for Disease Control and Prevention, found that only 7.4 percent of Americans aged 12 to 17 years old smoked marijuana regularly in 2014, a 10 percent decline since 2002. But 8 percent of 35 to 44 year olds used marijuana regularly in 2014, surpassing use among teens for the first time since at least 2002. (Survey data prior to that year aren't directly comparable, as the methodology changed.) And it's not just middle-aged folkswho are indulging more often. Since 2002, regular marijuana use among Americans age 45 to 54 has jumped by nearly 50 percent. Among those ages 55 to 64, it's jumped by a whopping 455 percent(no, that's not a typo). And among seniors, age 65+, monthly marijuana use is up 333 percent since 2002. "During the last 13 years, marijuana use (i.e., past-month marijuana use) has steadily increased in the United States, particularly among people aged 26 years or older," said report author Alejandro Azofeifa in an email. "Older groups had a significant increase of marijuana use in the past month." To put it another way: If trends continue like this, marijuana use among 50- and even 60-somethings could be higher than use among teens in a few years.
