Lot of really weird sh!t out there like spice (artificial marijuana) that will make a person do all sorts of nonsense.
Back in the '70s, used to be the strangest stuff was PCP-laced grass. It would make some people totally lose it, but as a side effect, it would give them almost superhuman strength. I watched as seven Long Beach cops tried to take down a 6-foot, 190 LB dude. The cops had limited success until one of them finally managed to get a pair of cuffs on the guy. When they stood him up, he broke the cuffs and the fight resumed.
This spice garbage is what the guy in Miami was on some years ago when he tried to eat his friend's face.
Staying in your truck was probably the better/safer idea.
