WACO -- It's like something out a horror film complete with zombie attacks, hysteria and sacrificing small animals.
But this time, it's real.
"It causes you to behave bizarrely because you may think things or hear or see things that are completely false," Dr. Martindale, who practices family medicine, formerly at The Freeman Center in Waco.
Which accounts for both the Miami incident, dubbed a "zombie attack," and the Waco man who acted like, then ate his family dog.
The cause? Synthetically laced incense like K-2, Spice and bath salts.
"K-2 or Spice is a mixture of natural herbs and often added with a fixative or an ingredient sprayed on it and it basically is a hallucinogen and it causes psychosis," Dr. Martindale said.
The drugs became illegal in Texas last September after the FDA recognized its harmful effects.
Now, without any regulation the list of what it could be laced with is endless.
"It's actually more dangerous because there's not even the semblance of supervision for what people might do with this."
But the good news? Doctors do say that since synthetic drugs do not give users desired effects of other illegal drugs, the popularity of K-2, bath salts and Spice will most likely fade away.
Waco Police tell us after the incident two weeks ago, they hope it serves as a very real example of why not to even experiment with the drugs.
