A new survey shows most US teens are abstaining from drinking, smoking and marijuana. Results from a large annual national survey found that teen drug use hasn’t rebounded from its drop during the early years of the COVID-19 pandemic. Fond du Lac County Public Health Officer Kim Mueller says about 67 percent of 12th graders this year said they hadn’t used alcohol, marijuana, cigarettes or e-cigarettes in the previous 30 days. Among 10th graders it was 80-percent, also a record.
