Whilst the rumor of The Outlawz smoking their fallen brother, Tupac's ashes in a joint is fairly well known, the rumor that Keith Richards snorted his father's ashes isn't all that widely circulated. As one of the most iconic Rock Stars of recent history, it's not all that surprising that it's true. Even more baffling, he felt no shame after the event.
The Rolling Stones's legendary guitarist openly admitted the fact that he snorted his father's ashes mixed with cocaine after his father died in 2002. He unashamedly told an English rock magazine journalist writing for NME the full details of the event. I don't think there's anything else left for Keith Richards to snort that would surprise us. In fact, that's probably one of the safest things he's snorted.
