A full house of concerned community members learned about the growing drug problem in the area Tuesday night.
The Onalaska Police Department put on a presentation called "Drugs in Our Community" at the public library.
It's a presentation they've put on about 30 times and it keeps changing with the trends.
Officers say the use of heroin continues to be the biggest problem. "Within the last three years it has just exploded. Some estimates I've seen are a 400% increase in heroin usage," said Onalaska Police Officer Jim Page.
"Parents are busy, but I think they have to learn to take time to learn what's going on in the community," said concerned community member John Sagen.
Presenters say it's not just heroin. Other drugs like bath salts and marijuana are common in the community as well.
