In Touch can exclusively reveal that the rapper, 39, took a drug test after his doctor called 911 and had him removed from his trainer's house in handcuffs, because it was unclear if he was under the influence at the time of his breakdown.

“[Kanye’s] doctor had no other choice but to call 911 for help because he was refusing to go to the hospital voluntarily. Kanye was having a total psychotic meltdown,” a source tells In Touch. “The doctor was asked if Kanye was on drugs, and he responded he didn’t know but wouldn’t be surprised if he was.”
