Prince Harry has revealed in his autobiography Spare that in the summer of 2002, when he was 17, he had “taken cocaine” during a shooting weekend.
The Duke added this was not a one-off and he had taken a "few lines" on other occasions, candidly describing his experience with the drug.
He said: "It did not make me feel as happy as it seemed to make others but it did make me feel different and that was my main goal. To feel. To be different”.
Prince Harry wrote: “I was a 17-year-old willing to try almost anything that would upset the established order.
"At least that was what I was trying to convince myself of.”

Prince Harry also opens up in his autobiography on his feeling towards his father Charles moving on with Camilla.
The Duke of Sussex said: “He had asked my grandmother for permission and she had grudgingly granted it, according to what was published.
"In spite of Willy and I begging him not to, my father proceeded with his plan.
"We shook him by the hand and wished him all the best without hard feelings.
"We recognised that he was going to be with the woman he always loved, the woman that fate had in store for him from the beginning.”
Harry continued: “I knew without a doubt that this marriage would drive our father away from us not in a literal sense, not in a deliberate or malicious way, but still . . . I would push him away.
"My father was entering a new space, a closed space, a strictly insular space.
"I sensed that Willy and I would see our father less and that made me feel mixed emotions.
“I wasn’t happy about losing a second parent and I didn’t know how to feel about having a step-mother who I thought had sacrificed me on her public relations altar.

"However I saw my father smile and it was difficult to deny it and even more difficult to deny the cause: Camilla.
“What I wanted in spite of everything was my father to be happy. Oddly enough I wanted Camilla to be happy. Maybe she was less dangerous when she was happy?”
He added: “I remember wondering just before tea if she would be cruel to me, if she would be like all the evil step-mothers of fairytales, but she wasn’t. Like Willy, that made me feel really grateful.”
