According to AMN healthcare, on registerednurse.com, Flakka is frequently referred to as the "zombie drug." It's a type of synthetic bath salt that causes all types of abnormal activity. "This drug affects people in ways no other drug ever has. People who use it have gone on mad, violent, zombie-like rampages." The DEA classifies Flakka as a schedule 1 drug with no medical uses.
According to AMN...

• Psychosis (experiencing hallucinations and or delusions) and severe delirium
o Delirium occurring as a result of Flakka may initially be hallucinations, hyperactivity, confusion, and disorientation; however, some people also develop a hypoactive delirium, often referred to as a “zombie-like state,” where the person is catatonic, not responsive, and may be hallucinating, delusional, or significantly confused

(Solutions Recovery, 2019)
It's called the zombie drug because it causes people to move erratically (jerking and contorting) along with self harm.
