Oklahoma's law enforcement community wants you to be aware of a sudden increase of drugs circulating around the state.
They say those drugs can be deadly to the touch.
According to the experts, designer drugs are becoming easier to make and more dangerous.
What's becoming more concerning is that Fentanyl-laced drugs are popping up in the mix. Some are so dangerous just one grain cold be enough to kill you.
Carfentanil, for example, is 10,000 times more potent than morphine.
A lot of the designer drugs hitting Oklahoma's streets have make ups that are constantly evolving, making it hard to get reference standards to compare them to.
"You see a lot of powder. Whether it's white, off white, gray, [and/or] tan, you don't know what that powder is until you actually get a definitive test on it," Tulsa police criminal intelligence analyst Harold Adair said.
Because these substances are so dangerous, police warn the public to call them if you see something questionable.
