Past-month marijuana

In spite of this drug education, past-month marijuana use among 10th and 12th graders has almost doubled in the last... 

Nationally, the National Household Survey on Dmg Abuse (NHSDA) estimated in 1999 that a third of the American population (72 million people) have tried marijuana at least once, but only 8.6% had used it during the past year. Figures decline even further when respondents were asked about more frequent use Only about 5.1% (11.2 million) of the American population aged 12 and older were monthly marijuana or hashish users.

The report also described a study of young...

Several times during the interview, he went to the bathroom to put his head under the hot shower, which he said improved his nausea. After a few minutes, Mr C terminated the interview saying he needed to stay in the shower. The next day he eloped from the hospital and was lost to follow-up.
