PHOENIX, N.Y. -- It was a tense scene Wednesday morning at John C. Birdlebough High School in Phoenix when a 15-year-old student suffered a seizure after taking a combination of prescription drugs.

"A grand mal seizure is complete convulsions and sometimes folks pass away from that because they'll swallow their tongue. But the nurse told me it was a grand mal seizure," said Village of Phoenix Police Chief Rod Carr.

Police say the student bought a combination of Ambien and hydrocodone from a 16-year-old student, who police later arrested. Authorities say they are seeing a trend of teens abusing prescription drugs such as pain killers and sleeping pills and the results can be deadly.

"Ambien and things that are sleeping agents really can make people very sleepy to the point where they become unresponsive and the problem really is when people start mixing drugs together, they are really at risk for significant toxicity from mixing of those drugs," said University Hospital Clinical Toxicologist Jeanna Marraffa.

Access seems to be a huge part of the problem of kids abusing prescription drugs. In addition to getting them from the family medicine cabinet, it is also becoming a lot easier to buy the drugs online.

"A lot of these online sites are really coming from different countries and it really is a huge risk and people really need to recognize the fact that, again, just because it's quote unquote prescription that it's not safe," said Marraffa.

Police are using the incident to urge parents to be careful about drugs they have in the home, saying it's a good idea to keep certain drugs stored away in a safe place and once prescription drugs have expired to throw them out.

"As a parent, you need to be mindful that kids will be kids and I don't know how many times in 37 years I've heard a parent tell me my child wouldn't do that and come to find out they did," said Carr.

In addition to being harmful, it's also a serious crime. The student who was arrested is due in court next week on felony drug charges.
