Chapman took up pipe smoking aged 15, which became a lifelong habit. He began drinking heavily during his time at Cambridge and St. Bartholomew's, favouring gin. By the time Monty Python went out on tour in 1973, Chapman's drinking had begun to affect his performance, causing him to miss cues to go on stage. He was known to suffer from delirium tremens (DTs). He stopped drinking during Christmas 1977, concerned about being able to act in Life of Brian successfully, and remained sober for the rest of his life.
