Bishop Kelley High School is the first school in Oklahoma to test students for alcohol consumption using hair samples.
The school says it's an effort to keep students safe from harmful substances.
Students will be randomly picked for the alcohol testing in the school year. If a student tests positive the first time, the principal will meet with the student and parent. The student will have to complete an alcohol education course.
Then, the student will be tested in 100 days.
If he or she tests positive a second time, the student could be expelled.
The lab results detect alcohol consumption from the past three months unlike a urine sample which is two or three days.
The high school started hair follicle testing in 2008 for drug use.
There's a $95 fee per student annually for the testing.
