'Train to Busan', a 2016 South Korean action horror film, became a reality for America when several videos last year showed people unable to stand and acting weird on the streets of Sierra Leone. Sierra Leone, a West African country, is in crisis due to the menance caused by a highly addicted psychoactive drug, xylazine, somethimes known as "tranq". President Bio issued a dire warning in a nationwide address, describing the drug epidemic as an existential threat: "Our country is facing a grave crisis from drug abuse, especially the deadly synthetic drug kush. "

Effects of Zombie virus on health

Addicts, suppliers and dealers have reportedly begun digging graves and removing bones from cemeteries in Freetown to make the drug. Due to the excessive quantity and toxic chemicals present in it, this danger is killing dozens of people every month.
According to the reports of doctors, Kush directly affects the vital organs of the body like heart, brain, liver, kidney and lungs due to which the addict can die at any time. Seeing the danger, the government has declared emergency and has deployed police guards outside the cemeteries to prevent theft of human bones.

Due to Kush abuse, several young men across the country, particularly in the capital Freetown, have been spotted high on street corners with swollen limbs- a common side effect of the drug. The intoxication of Kush is very cheap. An drug worth just Rs 800 is enough to keep them fed for the whole day.
