According to YTN's exclusive interview with Lee Sang-bo on September 14, the actor was revealed to have been consuming antidepressants, instead of illegal drugs.

Lee Sang-bo said, "I have never done drugs even once, and I don't have any relations to someone who does drugs. I have never, ever done drugs. The medicine that I'm currently taking is for my psychological stability."
The actor also showed a diagnosis report from the hospital, that he has been dealing with severe depression and consuming antidepressants regularly since 2019.
He argued that the positive result for the drug test came out due to the substances in antidepressants that he has been taking.

He said, "I suddenly woke up to the news of me being portrayed as a drug addict. People are obsessed with lies, and have no interest in what the truth really is. I don't know how long my life will last, but I will fight until the end."
Meanwhile, the police will conduct further tests on the antidepressants that Lee Sang-bo has been consuming, with the National Forensic Service.
