We can infer from the news that ______ of teenagers under survey in 1993 were dr

The University of Michigan carries out a survey of the drug habits among young people every year. And this year it concluded that the teenage drug use is rapidly getting worse. 25% of the teenagers surveyed said they used an illegal drug at some time in their lives, an increase of 3% from the figure for 1993. Marijuana use is climbing back towards levels not seen since the late 1970s. And today Marijuana is up to ten times more potent than in the past. Cocaine use, which leveled off in the early 1990s is also making a comeback among thirteen to fifteen-year-olds. The LSD, which had dropped considerably in the 1980s, is also on the rise.  Officials involved in the survey say the results indicate that young people no longer see drugs as dangerous. Instead the researchers say they are viewed as glamorous or trendy. The health secretary said it was time to sound the alarm and the secretary calls for a powerful antidrug message to be sent to children with parents leading the way.
