The actor will continue to play Alfie Solomons in the hit BBC series with a new episode airing earlier on TV tonight.
Hardy became sober at the age of 25 after checking into rehab in 2003.
Back in 2017, the 44-year-old said he could wreck a room within minutes if he had been consuming alcohol.
As reported in the Mirror, the father-of-three told the Daily Mirror: “If I had four pints of lager and half a bottle of vodka I could turn this room into an absolute f *** ing nightmare in about three minutes.
“” I could destroy everything in my life I have worked so hard for. “
“It’s the suburbs, life is so privileged and peaceful and so bloody dull, it gives you the instinctive desire to want to f ** k everything up.”
Tom had a “privileged and peaceful” childhood in South West London, but admitted he had to ‘endanger himself’.
“I got arrested at 15 for joyriding in a stolen Mercedes. And for good measure there was a gun in the car, ‘he revealed.
“I just had to endanger myself – it was a kind of self-harming.”
The acclaimed actor got his big break in Steven Spielberg’s TV series Band Of Brothers after being spotted in drama school.
However, Tom was battling a crippling drug addiction.
