A survey shows 50 percent of Wisconsin middle and high school students continue to use risky substances, if they've at least tried them once.
That's leading the advocacy group Rise Together to call on schools to do more, with prevention and education.
Sixty-eight percent said they've never tried alcohol, tobacco, and various drugs.
Co-founder Anthony Alvarado says they talked with nearly 3,000 kids at 70 schools last year. He says it's likely that some in the audience will end up dying from a disease of addiction, because of a lack of support.
The survey found that most students experiment for the first time out of curiosity, or because their friends are using the substance.
