Controversial Irish star Sinead O'connor enjoys marijuana on a daily basis.

The NOTHING COMPARES 2 U singer confesses that, although she shouldn't be mixing recreational drugs with her depression medication, smoking joints allows her to loosen up and cope with the stresses of life.

The 38-year-old says, "I've never had a drug or drink problem, other than that I'm a f**king major chronic spliffhead."

When asked how much she smokes she adds, "A fair bit. I smoke daily, put it that way. Maybe a quarter of an ounce a week. It's a lot. If I have friends round, I cane it."
