In researching the Beautiful Boy true story, we learned that Nic's life of addiction began with vodka when he was 11. A year later, he was smoking marijuana, which turned into a daily habit by middle school. He was soon experimenting with drugs like acid, ecstasy, mushrooms and cocaine. At the age of 18, he tried crystal meth. It made him feel like he could achieve anything. "I felt like a rock star," Nic says of the first time he used it. However, his feeling of euphoria didn't last long. As the fix wore off, the good feelings evaporated and his body writhed in agony. To keep the good feelings alive, he became an habitual user. He did everything he could to avoid crashing. As a result, the addiction consumed his life and directly affected the lives of his family members. The movie does a good job depicting this. -Oprah.com

Yes. Like in the Beautiful Boy movie, the real Nic Sheff kept journals. He used them as a resource when writing his bestselling memoir Tweak: Growing Up on Methamphetamines, which chronicles his experiences as a teenager addicted to drugs. Both Tweak and Nic's father's book Beautiful Boy provided the basis for the movie. -Oprah.com

Yes. Even by his senior year, drugs hadn't had a severe effect on Nic's academics. Like in the Beautiful Boy movie, the true story confirms that he got into the colleges he applied to but first ended up in rehab instead. When he made it to the University of California, Berkeley, he dropped out during his freshman year. -Oprah.com

Yes. "When this hit our family, we were like so many families in this country," David Sheff says. "I was not naive about drugs. I used drugs when I was a kid. ... But I still thought, like most of us, 'This could never happen to our family.' When it did, we were so blindsided. We were so devastated that I realized that this is something we have to talk about." That realization led David to write his book Beautiful Boy: A Father's Journey Through His Son's Addiction, which was published in 2008 and became a #1 New York Times Best Seller.

David says that he had shared and discussed his own history of drug use with his son, a decision that he questions today. -Oprah.com

Yes. This comes straight from David's memoir Beautiful Boy. He said that making the decision to share a joint with his son is one that he still regrets. "It was not something I'm proud of," says David, going on to explain that he was just trying to find a way to connect with his son. -Oprah.com

Yes. In the movie, Nic's second wife, Karen (portrayed by Maura Tierney), and their two small children, Jasper and Daisy, are all based on real people. Like in the film, they too suffered as David became obsessed with saving Nic. Jasper and Daisy idolized their older brother, who was their friend and playmate. They couldn't comprehend what he was doing to himself and how it was affecting the family. Nic knew that his drug use was destroying his family. He kept using in part to stop the guilt from sinking in. -Oprah.com

Yes. Sheff, who is a straight man, says that he also did it to feel wanted and to find value in himself. "I mean, don’t get me wrong, I needed the money. But, more than anything else, I wanted to feel beautiful," says Sheff. "I could’ve made money in other ways. Prostitution was something I wanted to do. That sounds crazy f**ked up, but it’s true. And when I was out there, you know, hustling, I’m telling you, a lot of the kids I met were just like me. They wanted to feel like I wanted to feel. They wanted to feel wanted."

"Of course, I’m straight, so I would’ve preferred to be wanted by women for sure. But, hell, I’d take what I could get. And men did seem to like me." Friends and family felt that he should leave the short period of time he spent prostituting himself in San Francisco and New York out of his 2007 book, Tweak: Growing Up on Methamphetamines. It is not depicted in the movie. -The Fix

Yes. He says that stealing money from his little brother's piggy bank in order to buy drugs is one of the lowest things he's ever done. "I would have practically done anything to anybody in order to keep getting it," says Nic. He also tried to steal a computer from his mother, Vicki. She found him in a paranoid state hiding in the ceiling rafters in the garage. -The Fix

David Sheff says that this indeed happened. For a period of time when his son was at his worst, David would check morgues and hospitals every couple days to see if Nic had died or overdosed. In the movie, Steve Carell's character calls hospitals in search of his son.

Yes. Though it's not shown in the film, the Beautiful Boy true story reveals that Nic almost lost his arm when an infected needle puncture grew to the size of a baseball. -The New York Times

Yes. Fact-checking the Beautiful Boy movie reveals that Nic eventually agreed to seek help. At first, rehab helped him to recognize that he had a disease, despite still believing that he could control his drug and alcohol use. As in most cases, staying clean was hard to maintain. He relapsed multiple times, and as of 2009, had been through five rehabilitation programs. -Oprah.com

Yes. As both David and Nic were working on their books, David suffered a brain hemorrhage, and his son, who had been off drugs for 18 months, relapsed. The hemorrhage affected David's brain in such a way that he had to relearn how to write. It is left out of the film. -The New York Times

"How is it that, today, I actually don’t totally hate myself?" Nic said in an article he penned for The Fix. "The only thing I can say is that I actually started listening and started doing what those counselors and psychiatrists and people in meetings were telling me to do. Hell, it was no big secret. They’d been prescribing me medication, telling me what outpatient groups to go to, what doctors to see, what steps to take. I just didn’t listen. I didn’t listen and I didn’t believe."

The movie is based in part on David Sheff's book Beautiful Boy. The book title comes from the 1980 John Lennon song "Beautiful Boy (Darling Boy)." Sheff interviewed John Lennon and Yoko Ono in September 1980, roughly three months before Lennon's murder.

In addition to working on his second book, Nic was living in Savannah, Georgia with his girlfriend and working as a nude model at a local art school. In 2011, he married Jette Newell, a model, actress and television writer. "That's what I care about now," he said in an article he wrote for The Fix, "I want to provide for the people I love. I want to take care of my dogs and to have kids one day and all that." Nic's second book, titled We All Fall Down, was published in 2011 and focuses on his ongoing efforts to stay clean as he suffers relapses and is in and out of rehab centers. He has since gone on to write for the Netflix TV show 13 Reasons Why.
