- Harsh chemical smells, or strong air freshener (can be used as an inhalant or to mask other smells)
- An unusual amount of empty aerosol cans.
- Products in your child's bedroom that shouldn't be there, such as whipped cream cans, paint thinner, cooking spray, nail polish remover in a boy's room, et cetera.
If you find anything that indicates that your child may be abusing inhalants, talk to them. Communication is the best defense against drug use.
