The percentage of teens who say they attend high schools with drug problems has increased from 44 percent to 61 percent since 2002, and the percentage in middle schools has increased from 19 percent to 31 percent, according to the survey to be released Thursday by Columbia University's National Center on Addiction and Substance Abuse.
And such activity is not easily hidden: The study has found that eight in 10 high schoolers and 44 percent of middle schoolers have witnessed illegal drug use, dealing or possession, or have seen students high or drunk on school grounds.
Thirty-one percent have witnessed this activity at least once a week.
According to the study, 17 percent of high school students say they could buy marijuana somewhere on their campus in an hour, while 37 percent say they could do it in a day, reports CBS News national correspondent Byron Pitts.
Some 13 percent of teens said they had tried marijuana, and 4 percent said they had used it in the past month. (Such survey results are often understated because respondents are hesitant to admit such drug use.)
The group calls institutions where illicit drug use is so rampant as "drug infested," and says popular kids who attending such schools are five and a half times more likely to use drugs than the same teens at drug-free schools.
"Those kids who consider themselves among the most popular were likely to get drunk at least once a month, likely to use drugs, likely to smoke marijuana," Joseph Califano, the center's chairman and president, told CBS News Early Show anchor Harry Smith. "The world these kids are living in, that's cool. We've got to change that."
"It has become such a commonplace experience for teens that their concern about it has come down," said Califano.
And with drug use becoming embedded in the high school experience, despair and denial are increasingly characterizing parents' attitudes.
Of parents queried in the survey, only 11 percent said drugs are their child's biggest concern. Asked how they'd feel if their kids smoked pot, 48 percent of parents said they were more worried about sex, 52 percent about shoplifting, and 82 percent about their child driving while intoxicated.
Califano, a former Secretary of Health, Education and Welfare, recommends that parents pull their kids out of schools where drug dangers are high.
"Parents refuse to send their kids to a school when asbestos is there." Califano told CBS News correspondant Barry Bagnato. "They'd refuse to send their kids to school if it were infested with rats.
"They've got to start saying, 'I'm not going to allow this situation to continue where my kids have to go to a school where drugs are used, kept and sold, or where they're going to see classmates that are high or drunk," Califano said.
The survey also found:
- About six in 10 parents of teens at schools with a drug problem say they believe the goal of making that school drug free is unrealistic.
- Most parents (86 percent) say drinking is a big part of the college experience, but only 29 percent think their own teens will do a lot of drinking in college.
- Students who consider themselves popular were more likely to use drugs, drink or smoke than students who do not view themselves as popular.
The survey of 1,063 teens from 12 to 17 years old and 550 parents was conducted from April 2 to May 13 and has a margin of sampling error of plus or minus 3 percentage points for the teen sample and 4 percentage points for the parents.
