TALLAHASSEE, Florida -- K2, Spice, bath salts: all of these are known as dangerous synthetic marijuana drugs. They're now illegal in Florida, but state health officials warn they're still causing big problems.
"With people who are, you know, just wanting to get the high for the night or whatever the case may be, they might not even realize or even care to realize what the effects are going to be for them."
That's what happened to Christopher Generoso.
In 2012, he admittedly got high on Spice in Tallahassee, and passed out on the road. He drove into the back of a car with an entire family. A mother, her son and son's friend all died in the crash.
Kristen Allen is with Mothers Against Drunk Driving.
"Drug driving is as serious a crime as drunk driving and it will be prosecuted," Allen said.
The Florida Department of Health says as of recently, dozens of people have become severely ill from the use of synthetic drugs.
"People don't know what they're buying or what they're getting, or even what they're ingesting."
The problem is nationwide. A University of Michigan study shows synthetic marijuana is the second most used drug among high school seniors.
They can produce some serious adverse effects: agitation, vomiting, tremors and seizures just to name a few.
Generoso was sentenced to 22 years in prison for that night. Many others have also been arrested for use or sale of these drugs.
"Just be safe, have that personal responsibility," Allen said.
Health officials say anyone experiencing an adverse reaction to a synthetic drug should contact a local poison center or 911.
