Celebrities are like regular people in that they occasionally overindulge in things they should consume in moderation.
But too many stars have battled drug addiction and alcoholism, and although many are currently sober, some still struggle to stay clean.
Lindsay Lohan, who charmed audiences with films such as "The Parent Trap," "Freaky Friday" and "Herbie Fully Loaded," has been to rehab six times to battle her addictions.
She told Oprah Winfrey in 2013: "(Alcohol) in the past was the gateway to other things, for me... I tried cocaine with alcohol... It allowed me to drink more. I think that's why I did it when I did it... I snorted it. I've never injected anything other than getting B12 (vitamin) shots. It went hand in hand with drinking."
