Tom Felton has addressed his struggles with mental health and drug addiction in his new memoir.

His new book, Beyond the Wand: The Magic and Mayhem of Growing Up a Wizard sees the Harry Potter star explaining the reason why he turned to alcohol and substance abuse.

Felton admits he started "drinking to escape" and spent many a time hanging out in dive bars "craving normality" when he was living in Los Angeles throughout his mid-to-late 20s.

"I went from being not particularly interested to regularly having a few pints a day before the sun had even gone down, and a shot of whiskey to go with each of them," he says in the publication.

"The alcohol, though, wasn't the problem. It was the symptom. The problem was deeper.” Felton tells his readers, as he begins to notice a deterioration in his mental health.

Beyond the Wand: The Magic and Mayhem of Growing Up a Wizard is out now published by Ebury Spotlight.
