Demi Lovato, Drew Barrymore on their fight against drugs and alcohol addiction

Demi Lovato and Drew Barrymore have recently shared their disturbing experiences with drugs and alcohol.

“It's hard to say that you don't blame other people when other people may have been giving you substances as a kid,” said Lovato, who uses she/they pronouns, in the new documentary, Child Star.

In the documentary, Lovato asked the E.T. star, “How old were you when you were first given something?”

Barrymore, who got her first acting job at 11-month-old, responded, “I used to get high with my mom's friend at like 10. And I thought she was so cool, and she would give weed to me and her son.”

“It's hard to not blame someone else when you're ten years old,” remarked the Camp Rock actress.

Reflecting on their childhood, she noted, “Those were all my actions, those were my reactions. That was my coping mechanism.”

“I'm very accountable, I don't blame other people,” stated the singer.

The Never Been Kissed actress mentioned, “Having a 10-year-old daughter now, I just, it's unfathomable. But that's just how I grew up.”

To note, Child Star is the fourth documentary where Lovato has chronicled her unstable childhood and struggle to avoid addiction and eating disorder

The songstress discussed about her struggles against drug and alcohol addiction they endured after rising to Disney fame on series like Sonny With a Chance and movies like Camp Rock.

Meanwhile, Barrymore called herself a “walking cautionary tale,” as she confessed about alcohol addiction at only 13 years old.

Now sober, the Charlie’s Angels actress said she saw her “fight to stop drinking as one of the most honouring things I can do to the Barrymore name because we have all been such hedonists”.
