Plan B has admitted that he smoked heroin when he was younger at Glastonbury festival.
The rapper, who will appear at this year's Glastonbury festival, said that he took heroin once at the festival when he was sixteen.
"I was 16 and didn't have any money. The first night me and my mate popped a couple of pills. The next night this northerner asked us if he could use our fire and we were too scared to say no," Plan B told The Sun.
He added: ''He got this foil out and started smoking heroin. Then he asked if we wanted some. So, like idiots we took some of his heroin and on the last night we smoked it"
"It was the first and last time I ever did it. I'm never going near it again. My head was spinning like I was drunk. I was hot then I was cold, I was itching all over, it was horrible."
Plan B's anticipated follow-up to 2010's Defamation Of Strickland Banks' will be released later this year.
