Chicago police are investigating a video posted to Facebook that appears to show a diaper-clad toddler smoking a marijuana joint as a man off-screen encourages the boy to “Inhale it.”

A community activist yesterday tipped cops to the clip, and Special Victims Unit detectives are now trying to identify who filmed the video, according to a Chicago Police Department spokesperson.

It is unknown when or where the video--which was posted to the Facebook page of a Chicago resident--was recorded.

Seen below, the 17-second clip found on Facebook shows the video playing on the screen of a cell phone, and it includes markings indicating that it may have previously been uploaded to some video sharing site.   

In the clip, a man’s voice is heard directing the toddler to "Smoke, bro. Inhale it.” The man--who appears to be filming the boy with his cell phone--then says, “Let me hit that, okay?”

If investigators succeed in identifying the suspect, he will face assorted charges, including child endangerment.
