The drug is essentially grounded up potpourri sprayed with dangerous chemicals. Kush can cause comatose or aggressive behavior. Some people even describe users as "zombie-like."
Turner vowed with added police patrols Houston would "take back our parks."
"We cannot allow these areas to remain as they are, and especially for our libraries," said Turner. "We can't get to the point where people don't want to come to the library because they don't want to walk through the traffic and subject to the abuse trying to get there."
Turner warned residents not to give money or food to the homeless, because it will only make the problem worse.

"It's just a scary place to come. There are vagrants and derelicts. I mean it's just not safe. We don't feel safe coming here," said resident Claudia Macias. "We're here because we like to be so close to downtown, but at the same time, we don't use a lot of the amenities just because the vagrants have kind of taken over those amenities."

Last week, 16 people were taken to the hospital after possible overdoses on Kush, according to the Houston Fire Department.
