During an interview with Metal Hammer, the legendary bassist of Guns N’ Roses, Duff McKagan revealed the details of his worst experience with drugs at the age of 15.

Guns N’ Roses icon Duff McKagan joined an interview for Metal Hammer magazine and opened up about his drug usage while he was a teenager. The interviewer asked Duff about his worst experience on drugs and he told a memory from his young ages. Apparently, Duff had a bad experience with mushrooms while he was only 15 years old.

Here’s what Duff McKagan stated about his worst memory of him taking drugs:

“I was about 15 and I took too many mushrooms. Mount St. Helens erupted in front of my face, and then trolls crawled out of my heart.

I was in the back of my friend’s car, totally overdosed on psychedelics, and hoodlums started beating up on our car… while I was watching trolls climb out of my heart.

But I had tickets to see the Iggy Pop show in my pocket and I was getting there no matter what! I just watched Iggy and he brought me out of my bad trip.”

Furthermore, they asked him about his thoughts regarding the recent popularity of the films portraying rock legends’ lives and Duff answered:

“I don’t know. I kind of like to have my memories of those people unsullied. I am a huge Queen fan, so I saw ‘Bohemian Rhapsody’ and if it had been a blank screen with two hours of Queen’s music I’d have loved it, but there were some obvious factual inaccuracies that I could have pointed out.

But I don’t want to be that guy. I’ve seen ‘The Dirt,’ too, and it kind of captured the darkness of the ’80s Sunset Strip scene… And I’ve got ‘Lords of Chaos’ on my watchlist. But, really, I spend my whole life in rock ‘n’ roll – I’d rather read a history book.”
