According to his memoir 'Spare', Prince Harry has spoken about his past
drug use during his school days.
He confessed that he and his friends had a method of taking drugs late at night in the dorms, and he often had a constant desire to do so.
Although he can't remember how they obtained the drugs, they had a system in place where they would gather in a small bathroom upstairs, where they would form an assembly line.
The first person would smoke the weed while sitting on the toilet next to the window, the second leaned against the basin, and the third and fourth would sit in the empty bathtub with their legs dangling over.
They would rotate the positions and take turns smoking the weed until it was all gone. Afterward, they would all go to one of their rooms and laugh uncontrollably.
