Eminem has celebrated 18 years of sobriety, marking a significant milestone after his past struggles with prescription drug addiction.

The Real Slim Shady rapper, whose real name is Marshall Mathers III, shared the achievement on Instagram this week, posting a snap of himself holding a sobriety token.

The coin featured the phrase "To thine own self be true" around its outer edge, while the words "unity, service, recovery" were arranged in a triangle at its centre, surrounding the number 18 in Roman numerals.

The 53-year-old captioned the post simply, "XVIII (gold medal emoji)."

A number of stars were quick to congratulate Eminem in the comments, including Questlove, who wrote, "Awesome. Keep Goin." Meanwhile, Big Sean added, "Yessir! Keep it up."

The rapper has previously spoken candidly about his addiction to prescription medication, including Xanax, Ambien and Vicodin, most recently in his 2025 documentary Stans. He explained that his dependency began in the late 1990s and escalated until a health emergency in 2008.

"I got into this vicious cycle of, 'I'm depressed so I need more pills,'" he said at the time, via Us Weekly. "Then your tolerance gets so high that you end up overdosing."

"I woke up in the hospital and I didn't know what happened," Eminem continued. "I woke up in the hospital with tubes in me and s**t and I couldn't get up, I wanted to move."

The rapper went on to reveal that missing one of his eldest daughter Alaina Marie's birthdays proved to be the wake-up call that he needed.

"I cried because it was like, 'Oh my god, I missed that,'" he shared. "I kept saying to myself, 'Do you want to f**king miss this again? Do you want to miss everything? If you can't do it for yourself, you f**king p**sy, at least do it for them.'"

The Mockingbird rapper added, "I realised I'm never doing this again."
