Around 1:30 p.m. Tuesday afternoon, the Waco Police Department responded to the 1600 block of West Ave. to a call of a woman who was found unresponsive after smoking a 'K-2 like substance'.

According to police, the woman was still unconscious when authorities arrived to the scene. Paramedics revived the woman using smelling salts and the woman refused to go to the hospital, Waco PD Sgt. Patrick Swanton said.

Tuesday's incident marks the third incident related to K-2 in July.

One man died in his Waco apartment July 8 after he collapsed from smoking K-2, and 3 others were hospitalized July 9 after smoking the drug outside a Waco bar.

Swanton told Channel 6 the substance smoked by the woman was 'similar' to the substance smoked in the other two incidents this month.

"Smoking this K-2 like substance is similar to putting a loaded gun to your head," Swanton told Channel 6.

According to the National Institute on Drug Abuse, 11,406 ER visits in 2010 were associated with synthetic marijuana, also known as K-2 or Spice. 75 percent of those visits were among adolescents and young adults ages 12-29, 22.5 percent of the visits involved females, and 77.5 percent involved males.

Swanton added the drug is extremely dangerous and is nothing to experiment with.
