Tatum O’Neal’s Rescue Me co-star Dennis Leary is convinced the drama series will help her stay sober — because her character will also be forced to kick alcoholism, imdb.com reports.

She was charged with a minor narcotics offence earlier this month after police caught her exchanging money with a dealer three blocks from her New York home.

She claimed the incident was her first lapse in sobriety after a longterm battle with drug addition. O’Neal subsequently joined a recovery program for alcoholics.

And Leary — who plays O’Neal’s brother on the show — is convinced that as her character is battling a drinking problem in the upcoming second season, she will be able to put the experience to use in real life.

He tells AOL Television, “(Her character, Maggie) got clean at the end of last year and we have this game plan for her that involves staying sober, so it’s probably gonna work in Tatum’s favour. We were in the middle of planning the next bulk of Tatum’s work before (her drug bust), so she’s got a place to come back to.”
