A Colorado Springs teenager who has been missing for days is fighting for his life right now after his family says he used the dangerous drug, Spice.
Joshua Walker, 19, lives with his grandparents. Even though they've found him, the heartache is far from over. They say doctors told them they are pumping synthetic marijuana from his body.
Joshua left his grandparents' home last Thursday and never returned.
“We started getting real worried,” grandfather Kendall Walker said.
“It was scary, I thought he might be dead,” Verda Donally recalled.
As the days passed, their concern grew. Kendall called police. The family also posted pictures of him all around town. Then they made a startling discovery.
“My son went downtown putting up fliers and somebody saw him...said there's a flyer like that and a picture of him in the soup kitchen.” Kendall said.
According to Kendall, Memorial Hospital made a John Doe poster with Joshua's image on it and hung it in the soup kitchen. The Walker family rushed over to the hospital, but their hearts sank when they learned their grandson was in a coma. Doctors told them he had taken Spice.
Kendall doesn't want any other family to go through this.
“Talk to your kids about Spice. That it will kill them."
The grandparents tell 11 News the doctors may be able to remove Joshua's breathing tube on Wednesday.
In the last month in Colorado more than 150 people are believed to have been sickened by synthetic marijuana and three people may have died from it. Also known by names like "Blaze" and "Black Mamba," officials say what makes Spice so dangerous are the chemicals sprayed on the plants that make up the herbal mixture. The chemicals can cause deadly side effects.
