Marijuana(大麻) use among college students is on the rise in the United States. Studies of American college students show that daily marijuana use was more popular than cigarette smoking for the first time last year.
Studies found that 5.9 percent of college students said they use marijuana nearly every day. Students have smoked at least 20 times in the earlier 30 days. That is a 3.5 percent increase from 2007, and the highest rate since 1980. Only five percent of college students reported using tobacco(烟草) daily. More students are experimenting with the drug for the first time, as well.
Twenty-one percent of students reported having used marijuana once or more in the earlier 30 days. That is a 4 percent increase from 2006. Thirty-four percent of those questioned said they used marijuana in the earlier year, four percent more than in 2006. However, the levels appear to have leveled off(平稳) since 2014.
Lloyd Johnston was the lead researcher. He said, “It’s clear that for the past seven or eight years there has been an increase in marijuana use among the nation’s college students. And this largely parallels(同步) an increase we have been seeing among high school seniors.”
Mr. Johnston said the main driver for the increased use of marijuana is the belief that it is not as dangerous as tobacco. He pointed to studies of high school graduates between the ages of 19 and 22. In 2006, 55 percent of those questioned said regular use of marijuana was dangerous. Eight years later, that number dropped to 35 percent.
He said this is probably a result of increased legalization of medical and recreational(娱乐的) marijuana use. It is legal to use marijuana for recreational purposes in four U.S. states and three U.S. cities. Twelve other states have legalized marijuana for medical purposes.
