As various members of Guns N' Roses began to encounter serious problems with drugs, namely heroin, Axl Rose decided to give the band an onstage ultimatum during a 1989 opening slot with the Rolling Stones.

Rose declared that if certain members of the band didn't stop "dancing with Mr. Brownstone," which references a GN'R song about heroin, Rose would quit the band. Slash reportedly promised Rose that he would kick his addiction, but drummer Steven Adler was unable to kick his habit. See what happened to him next:
