Harry Potter star Daniel Radcliffe is reportedly set to check into rehab to help him kick his dependence on cigarettes.

According to the Daily Star, the 24-year-old actor will spend time at a rehabilitation facility offering counselling, sport activities and herbal remedies to assist in his battle to quit smoking.

A source said: ''It will be a kind of residential treatment programme, involving counselling, both individual and group stress management and herbal treatments to help withdrawal symptoms.

''There's also a full exercise activity programme, which includes swimming, running and yoga.''

Radcliffe, who has struggled with alcohol addiction in the past, is said to smoke 20 cigaretteres a day, but is determined to kick the habit.

The source said: ''Daniel knows he has an addictive personality, and he's been open in the past about his drinking demons.

''Thankfully he managed to kick the bottle. So now he sees cigarettes as his last major vice to conquer and he is confident he'll succeed once again.''

The former child star previously admitted that at the height of his fame he would often stay at home and drink so much he would "black out".

He said: "The drinking was unhealthy and damaging to my body and my social life. That's beyond question.

''I was living in constant fear of who I'd meet, what I might have said to them, what I might have done with them, so I'd stay in my apartment for days and drink alone."

He added: ''I was a recluse at 20. It was pathetic -- it wasn't me. I'm a fun, polite person and it turned me into a rude bore.''
