Cigarette and alcohol use at historic low among US teens

But continued high levels of abuse of alternative tobacco products, marijuana and prescription drugs

Cigarette and alcohol use by 8th, 10th and 12th-graders in the US are at their lowest point since the Monitoring the Future (MTF) survey began polling teenagers in 1975, according to this year's survey results. However, this positive news is tempered by a slowing rate of decline in teen smoking as well as continued high rates of abuse of other tobacco products (e.g., hookahs, small cigars, smokeless tobacco), marijuana and prescription drugs. The survey results appear to show that more teens continue to abuse marijuana than cigarettes; and alcohol is still the drug of choice among all three age groups queried. MTF is an annual survey of 8th, 10th, and 12th-graders (aged 13 to 18) conducted by researchers at the University of Michigan, Ann Arbor, under a grant from the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health. The survey was conducted in classrooms in 2011.

Binge drinking decline

For alcohol, 63.5 percent of 12thgraders reported past year use, compared to a recent peak of 74.8 percent in 1997. Similarly, 26.9 percent of 8th-graders reported past year use of alcohol in 2011, compared to a recent peak rate of 46.8 percent in 1994. There also was a five-year decrease in binge drinking, measured as five or more drinks in a row in the past two weeks, across all three grades. Binge drinking was reported by 6.4 percent of 8th-graders, 14.7 percent of 10th-graders, and 21.6 percent of 12th-graders, down from the 2006 rates of 8.7 percent, 19.9 percent and 25.4 percent respectively.

Smoking down

The 2011 results showed that 18.7 percent of 12th-graders reported current (past-month) cigarette use, compared to a recent peak rate of 36.5 percent in 1997 and 21.6 percent five years ago. Only 6.1 percent of 8th-graders reported current smoking, compared to a recent peak of 21 percent in 1996 and 8.7 percent five years ago.

“That cigarette use has declined to historically low rates is welcome news, given our concerns that declines may have slowed or stalled in recent years,” said NIDA director Dr Nora D Volkow. “That said, the teen smoking rate is declining much more slowly than in years past, and we are seeing teens consume other tobacco products at high levels. This highlights the urgency of maintaining strong prevention efforts against teen smoking and of targeting other tobacco products.”

Despite the declines noted in the report, use of marijuana has shown some increases in recent years and remains steady. Among 12th-graders, 36.4 percent reported past year use, and 6.6 percent reported daily use, up from 31.5 and 5 percent, respectively, five years ago. The upward trend in teens' abuse of marijuana corresponded to downward trends in their perception of risk. For example, only 22.7 percent of high school seniors saw great risk in smoking marijuana occasionally, compared to 25.9 percent five years ago. Similarly, 43.4 percent of 8th graders reported that they saw great risk in smoking marijuana occasionally, compared to 48.9 percent five years ago. In addition, concerns about the use of synthetic marijuana, known as K2 or spice, prompted its inclusion in the survey for the first time in 2011. Surprisingly, 11.4 percent of 12th-graders reported past year use.

There was mixed news seen in the non-medical use of prescription drugs. Abuse of the opioid painkiller Vicodin was reported by 8.1 percent of 12th graders -- similar to 2010 and down from 9.7 percent in 2009. There was also a decline reported by 10th graders -- to 5.9 percent from 7.7 percent in 2010. However, no such declines were seen for the opioid painkiller OxyContin.
