Early in the morning of November 1, news outlet Dispatch reported that WONHO was recently tested for illicit drug use.
They said that in September when WONHO arrived at Incheon International Airport on a plane from Frankfurt, Germany, strands of WONHO's hair were taken for a hair follicle drug test.

STARSHIP Entertainment stated, "When MONSTA X returned from Germany in the end of September, WONHO's belongings and body were checked at the airport. It was really short that we all thought that it was just part of customs inspection and that was what we were told at that time."
The agency continued, "We were completely unaware that the check was part of police investigation and the police were investigating him for suspected marijuana use in 2013."
