Robbie Williams has written on his blog about the first time he took LSD as a teenager, which resulted in him deciding to stab himself.
Williams wrote: "It was at Shelleys [nightclub] where I had my first acid experience. We were in Golden Hill, in someone's kitchen probably. I was given a tiny piece of paper to ingest. Es were too expensive for the Potteries. £15 - who could afford that? There was a band called the Prodigy performing that night and I thought they were really good. Afterwards we drove up to the garage and the police were on the forecourt. Shit, I thought. I want to go home, I'm scared. There is only one place I want to be - at home with my mum".
He continued, saying that he began to hallucinate when he finally did make it home: "American footballs were coming out of the TV. So I decided to go downstairs and stab myself. Mum came out of her room and said, 'What are you doing?'" [I replied,] 'I'm just going downstairs to stab myself - do you want a cup of tea?'"
PS: Legal disclaimer - we would not recommend handling boiling water when under the influence of LSD. Especially if you're stabbing yourself. Getting the blood off your mum's white china tea set would be a nightmare.
