Some parents are going through extreme measures to keep their children drug free: Hiring drug-sniffing dogs to search their home.
Trained narcotic detecting dog Roxy and her handler, Kristin Mauer, make house calls as part of a service called Confido Searches for parents who suspect their kids are using drugs.
"If you suspect drug use, you could use this dog and find evidence if there is some, then have that talk," said Peggy Dwyer.
Dwyer hired Confido Searches to canvas her home. She is a mom who noticed behavioral changes and problems in her 15-year-old son. She discovered he was abusing alcohol.
"When we started to breathalize him, he switched to pot," Dwyer said.
The Dwyer family decided residential treatment was best for him, but Dwyer wanted to make sure nothing was hidden that could cause her son to lapse back into old habits when he came home from treatment, so she hired Mauer.
"My goal is to help parents confirm or deny suspicions without accusing the child of something," Mauer said.
For legal reasons, Mauer never sees the drugs herself. With the help of Roxie, she just points parents in the right direction.
Roxy has found drugs stashed behind air conditioning vents, also taped to walls in the attic, places parents don't always think to look.
"I wish I had known about this in the beginning," Dwyer said. The cost of a Confido Search is $500 and it is confidential. Confido Searches is based in Houston.
