PLEASANT HILL -- The public is invited to attend a free presentation on teens and substance abuse Thursday at College Park High school.

The presentation begins at 7 p.m. in the school library at 201 Viking Dr., Pleasant Hill. Jason Lechner, the school's support counselor and an addiction specialist, will lead a discussion focusing on drug and alcohol use by students previously considered unlikely, including high-level athletes and top academic achievers.

The discussion will look at how the adolescent drug culture has changed over the years. Professionals, parents and some teens will participate.
