Actress and singer Amanda Bynes rose to fame in her early teens on the Nickelodeon sketch show "All That" before getting her own comedy sketch show, "The Amanda Show," from 1999 to 2003. She also starred in movies such as "Big Fat Liar," "What a Girl Wants" and "She's the Man" as well as the sitcom "What I Like About You."
After 2012 saw Bynes deal with a DUI arrest and two hit-and-run incidents, the actress received three years' probation after pleading no contest on May 9, 2013, to driving with a suspended license. But that was just the start of her problems. Later that month, she was arrested after police said she threw a bong from her Manhattan apartment. She was again detained on July 22, 2013, after allegedly starting a small fire in the driveway of a stranger's house in Thousand Oaks, Calif. The incidents led to her being put under a involuntary psychiatric hold and her parents winning a temporary conservatorship over her affairs. In the fall, she was moved from UCLA Medical Center to a private treatment facility outside Los Angeles for "specialized treatment." She was released into the custody of her parents in early December to continue her recovery at home.
Bynes had been doing well since her hospitalization, but in September 2014 she was arrested for DUI again in Sherman Oaks, California, after stopping for a red light in the middle of an intersection. She was accused of being under the influence of an unknown drug.
Bynes was on an involuntary psychiatric hold in a facility in Los Angeles for weeks, but was released on Oct. 30. Since then, Bynes has been roaming the Los Angeles area, acting erratically at restaurants and being denied rooms at various hotels. In Nov. 2014 she Tweeted that she has bipolar disorder and claimed to be taking medication and seeing a psychiatrist.
Drew Barrymore had a breakout role as a 6-year-old in Steven Spielberg's "E.T." in 1982. As a child she also starred in the movie "Firestarter" and even hosted Saturday Night Live at age 7.
By her own admission, Barrymore had begun drinking and smoking cigarettes by the age of 9, smoked marijuana at 10 and started using cocaine at 12. It took two stints in rehab in her early teens before she found sobriety.
Judy Garland was signed to Metro-Goldwyn-Mayer as a teenager and made more than two dozen films, including nine with Mickey Rooney as well as playing Dorothy in 1939's "The Wizard of Oz," the role she is most often associated with.
Garland had a long struggle with alcohol and drug use during most of her career, dying of an accidental drug overdose at the age of 47 on June 22, 1969.
Getting his start at age 3 in a McDonald's commercial, Corey Feldman counted roles in two "Friday the 13th" movies, "Gremlins," "The Goonies," "Stand By Me" (pictured), "The Lost Boys" and "License to Drive" on his resume by the time he was 18.
A growing addiction to drugs reached a breaking point for Feldman when he was arrested for heroin in 1990 at 19 years old. After two more drug arrests, he got sober and has now been drug-free for nearly two decades.
Feldman's seemingly constant co-star throughout the 1980s -- so much so that they earned the nickname "The Two Coreys" -- was Corey Haim. The two starred together in "License to Drive," "The Lost Boys," "Dream a Little Dream" and several more films. Haim also starred in movies like "Silver Bullet" and "Lucas" (pictured).
His career derailed by drug problems, including more than a dozen stints in rehab, Haim made a slight comeback in the mid-2000s, including a reality show with Feldman called "The Two Coreys." He also landed a supporting role in 2009's "Crank: High Voltage," but continued to battle an addiction to prescription painkillers. He ended up dying at age 38 on March 10, 2010, due to pneumonia.
River Phoenix was an actor and teen icon in the 1980s. He began acting at age 10, and was nominated for an Academy Award for his role as Danny in "Running on Empty" in 1988. Other memorable roles came in "Stand By Me" (pictured), "Explorers," "The Mosquito Coast" and "Little Nikita."
In his early 20s, Phoenix began using drugs like marijuana, cocaine and heroin. He died of a drug overdose at age 23 outside the Viper Room, a Hollywood nightclub, during the early morning hours of Oct. 31, 1993. An autopsy later found his body contained toxic levels of cocaine and heroin, as well as traces of marijuana and Valium. He's seen here in his final completed film, 1993's "The Thing Called Love."
In the 1980s, Todd Bridges found fame for playing Willis Jackson on the sitcom "Diff'rent Strokes" (pictured, left, with Gary Coleman) winning the role at the age of 13. At the peak of his fame, he was making $15,000 an episode and owned his own home in Los Angeles at age 18.
In his 20s, Bridges battled a crack cocaine addiction for several years. He was arrested in 1983 for carrying a concealed weapon, in 1986 for making bomb threats, and in 1989 for pulling a gun on a mechanic, although the last charge was ultimately dropped. Later in 1989, he was accused of shooting a drug dealer while on a cocaine binge. He was defended by Johnnie Cochran and was eventually acquitted of the charges. After years of battling his drug addiction, Bridges became sober in the early 1990s.
Dana Plato played the older sister on "Diff'rent Strokes," but was written off the show in 1984 after she became pregnant at age 18. She returned for several appearances during the show's final 1985-1986 season.
Like Bridges, Plato found herself struggling to find acting jobs after the show, but her problems began while still on "Diff'rent Strokes." She overdosed on Valium at age 14 and later admitted to drinking and using marijuana and cocaine during her years on the show. Struggling with poverty and unemployment in the 1990s, she received five years probation for using a pellet gun to rob $164 from a video store in 1991 and was again arrested the following year, this time for forging a prescription for Valium. On May 8, 1999, she committed suicide at age 34, taking a lethal overdose of the painkiller Lortab and the muscle-relaxant Soma.
While Gary Coleman, the star of "Diff'rent Strokes," avoided the drug issues that plagued his co-stars, he had his own financial and legal problems. He successfully sued his parents and business advisor in 1989 over misappropriation of his assets, but still declared bankruptcy a decade later, largely because of health issues and medical bills. He pleaded no contest to punching a woman seeking his autograph in 1999, was twice arrested on disorderly conduct charges after domestic disputes in the late 2000s, and pleaded no contest to charges of disorderly conduct and reckless driving after a 2008 incident in which he backed his truck into a man who took his picture without asking his permission. Coleman died at age 42 of an epidural hematoma in 2010.
Scotty Beckett's showbiz career started at the age of 4, landing a part in 1933's "Gallant Lady" and then going on to star in the "Our Gang" short films, playing George "Spanky" McFarland's best friend and partner in mischief. He continued to find success well into his teens and early 20s.
Beckett was arrested on a concealed weapon charge and for passing a bad check in 1954, costing him his job as the comic sidekick in the popular TV show "Rocky Jones, Space Ranger." In February 1957, he was arrested after attempting to cross the Mexican border with 250 "stimulant pills." His rap sheet also included arrests for disturbing the peace, drunken driving, and attempted assault with a knife. He died in 1968, at the age of 38, from an overdose of barbiturates.
Robert Blake was another "Our Gang" star, appearing in 40 of the shorts between 1939 and 1944 and eventually becoming the series' final lead character. He also appeared in more than 20 movies in the "Red Ryder" western series, playing the Native American boy Little Beaver.
After a troubled childhood that Blake claimed included abuse by his alcoholic father, he got entangled in crime as a teenager. He carried a gun in a liquor store robbery and did jail time, but cleaned up his act after a stint in the military. His career reached new heights in the 1970s, starring in the TV police drama "Baretta," but in 2001 he was accused of murdering his wife, Bonny Lee Bakley, who was shot and killed in their car a block from where they had dined together. Blake was found not guilty of Bakley's murder in 2005, although he was later found liable in civil court for her wrongful death.
Jodie Sweetin grew up in front of TV viewers' eyes playing Stephanie Tanner on the 1990s family friendly sitcom "Full House."
Sweetin has acknowledged having a serious substance abuse problem most of her adult life, saying she first tried methamphetamine after "Full House" ended because she was "bored." In her 2009 memoir "unSweetined," she discusses delivering an emotional address at Marquette University about how much her life had improved since getting sober -- all while coming down from a two-day bender of meth, cocaine and ecstasy. However, she has said she has been clean and sober since March 2005.
Lindsay Lohan began modeling as a child and was a regular on the soap opera "Another World" by the time she was 10 years old. She made her movie debut at age 11 in the 1998 remake of "The Parent Trap" (pictured), and went on to star in movies like "Freaky Friday," "Mean Girls," "Herbie: Fully Loaded" and "Prairie Home Companion."
Lohan's career started hitting the skids in 2007, when two driving under the influence incidents led to her being put on probation. Her legal issues, together with three visits to rehabilitation facilities, cost her several movie deals. But that was just the start of her legal problems. She has spent between 84 mins and 14 days on several stints in jail for violating probation on misdemeanor theft and DUI convictions, being released early each time due to overcrowding, and spent another 90 days in court-ordered rehab in 2013 after pleading no contest to charges of reckless driving, lying to police and obstructing police in connection with a June 2012 car crash in Santa Monica, Calif.
Danny Bonaduce played the precocious Danny Partridge on the 1970s musical sitcom "The Partridge Family."
After the show ended, Bonaduce began experimenting with drugs in his late teens and early 20s. He's been arrested several times, including high-profile arrests in 1990 for attempting to buy cocaine in Daytona Beach, Fla., and in 1991 on charges of robbing and beating a transvestite prostitute in Phoenix. He chronicled his struggles with drug addiction, rehab, homelessness and arrests in the 2002 autobiography "Random Acts of Badness" and his unstable lifestyle was further on display in the 2005 reality TV series "Breaking Bonaduce."
In 1974, a 10-year-old Tatum O'Neal became the youngest Academy Award winner ever, winning an Oscar for Best Supporting Actress for her role opposite her father, Ryan O'Neal, in the movie "Paper Moon." She also went on to star in the movies "The Bad News Bears" and "Little Darlings" as a teen.
O'Neal detailed her dysfunctional childhood and dependency on heroin and cocaine in her bestselling 2004 memoir, "A Paper Life." After her 1994 divorce from tennis star John McEnroe, she began using drugs again and developed a heroin addiction. She was arrested on June 1, 2008, after allegedly buying cocaine near her Manhattan apartment building, eventually pleading guilty to disorderly conduct and agreeing to spend two half-day sessions in a drug treatment program.
Singer and actor Leif Garrett found fame in the late 1970s as a teen idol.
Garrett became infamous later in his adult life for his drug abuse and legal troubles. In November 1979, five days before his 18th birthday, Garrett crashed his car while drunk and high, leaving his passenger and best friend, Roland Winkler, a paraplegic. He eventually settled a negligence lawsuit filed by Winkler and his family for $7.1 million. Garrett and Winkler were estranged for years, but reunited on a memorable 1999 episode of VH1's "Behind the Music." He also had a series of drug arrests over the years, culminating in a no contest plea to heroin possession in 2010 that landed him in court-mandated rehab. His struggles with heroin were documented in the fourth season of "Celebrity Rehab with Dr. Drew," which aired in 2010-11.
Mackenzie Phillips appeared in the movie "American Graffiti" as a 12-year-old and starred as rebellious teenager Julie Cooper Horvath on the sitcom "One Day at a Time."
Phillips (left, with Valerie Bertinelli) was arrested for public drunkenness and possession of cocaine in her late teens in 1977 during the third season of "One Day at a Time." Her drug and alcohol abuse eventually led to her being fired from the show in 1980. She went through rehab in 1981 following two nearly fatal overdoses, but didn't get clean until entering a nine-month intensive drug rehab program in 1992. In her 2009 autobiography "High on Arrival," she claimed she had a decade-long incestuous relationship with her father, John Phillips of The Mamas & the Papas, who had also got her addicted to cocaine.
Macaulay Culkin became one of the biggest child stars of the 1990s by playing Kevin McCallister in "Home Alone" and "Home Alone 2: Lost in New York." He also appeared in movies such as "Richie Rich," "Uncle Buck," "My Girl" and "The Pagemaster."
Culkin, seen here in 2010, was arrested in Oklahoma City in September 2004 on charges of possession of marijuana and the prescription drugs Alprazolam and Clonazepam. He initially pleaded not guilty, but later reversed his plea to guilty and received three one-year suspended prison terms. In 2012, the National Enquirer published paparazzi photos of the actor looking gaunt and dishevelled, claiming he had become hooked on heroin and pills after getting dumped by Mila Kunis, whom he had dated for eight years. Culkin's representatives denied the allegations and he made a rare public appearance at the New York Comic Con in October 2013 looking healthier and more muscular.
Actor Brad Renfro made his film debut at the age of 11 in the lead role of "The Client" (pictured). He also appeared in movies such as "Sleepers," "Apt Pupil" and "Deuces Wild."
Renfro's career faded rapidly due to alcoholism and substance abuse. He was first arrested at age 15, accused of carrying two small bags of cocaine in a cigarette box and a bag of marijuana in his sock. He avoided trial with a plea bargain requiring him to be screened randomly for drugs and undergo substance abuse evaluation. He was arrested several more times, including a high-profile arrest in December 2005 on charges of attempting to buy heroin off an undercover officer, with a photo showing him in handcuffs appearing on the front page of the Los Angeles Times. Renfro died from a heroin overdose at the age of 25 on Jan. 15, 2008.
At the age of 5, Brian Bonsall won a role on "Family Ties," playing Andy Keaton, the family's youngest child. He joined the series during its fifth season in 1986 and stayed with the show through its finale in 1989.
Bonsall also had a recurring role in "Star Trek: The Next Generation," appearing in seven episodes in 1992-94 and then appeared in two TV movies, "Father and Scout" with Bob Saget and "Lily in Winter" with Natalie Cole, both in 1994. Since retiring from acting in 1995, Bonsall has had a number of run-ins with the law, including a 2001 DUI conviction and assault convictions in 2007 and 2010.
Edward Furlong made his film debut at the age of 13, playing John Connor in "Terminator 2: Judgment Day." The role earned him Saturn and MTV Movie Awards for his breakthrough performance. He went on to appear in movies such as "American Heart," "Pet Sematary Two," "American History X" and "Detroit Rock City."
Furlong's career path got bumpy starting in his 20s due to multiple arrests and court cases, and chronic substance abuse and alcoholism. In a December 2006 interview with People magazine, Furlong said that from 22 to 26 he was "on and off" hard drugs, including heroin and cocaine. He has also been arrested several times on domestic violence charges and pleaded no contest after his most recent arrest in May 2013, avoiding a jail sentence in exchange for agreeing to 90 days in drug rehab and 52 weeks of domestic violence counseling. Despite his legal issues, his career has rebounded a bit, with supporting roles in 2011's "The Green Hornet" and 2013's "Assault on Wall Street" (pictured.)
While filming "Detroit Rock City," Furlong dated co-star Natasha Lyonne, a fellow former child actor who got her start at age 6 on "Pee-wee's Playhouse." She also had roles in movies such as "Heartburn," "Dennis the Menace" and "Everyone Says I Love You" before landing starring roles in "Slums of Beverly Hills" (pictured) and "But I'm a Cheerleader" and her most high-profile role in the "American Pie" film franchise.
In August 2002, Lyonne pleaded guilty to a drunken driving charge stemming from an arrest the year before. In 2006, she was arrested after trashing a neighbor’s apartment and threatening their pet, but charges were later dropped. Then addicted to heroin and alcohol, the actress has said she was "as good as dead" during that period. She has since given up all her vices, including cigarettes after having open heart surgery in early 2012 and has seen a bit of a career resurgence since getting clean, including a brief reprisal of her "American Pie" character in 2012's "American Reunion," and a regular role on the Netflix comedy series "Orange is the New Black."
Britney Spears (front, right) got her start in 1993 on the sixth season of "The All-New Mickey Mouse Club," starring alongside the likes of fellow child stars Justin Timberlake (far right), Christina Aguilera (second from right) and Ryan Gosling (front, left). She released her debut album, 1999's "...Baby One More Time," at the age of 17 and quickly became an international pop star.
Spears raised eyebrows between 2007-08 when she shaved her head at a local salon, took an umbrella and smashed it against a paparazzo's car window, dated a paparazzo, exposed herself, checked into rehab, lost custody of her kids and locked herself in a bathroom with her children. At the tail end of that behavior, she was also taken to UCLA Medical Center, where she underwent a mental evaluation and suicide watch for 72 hours. Soon after, her parents got a restraining order against her former manager. She is still under a conservatorship with her father and has made a remarkable comeback to the music scene since then.
Bobby Driscoll was one of Disney's biggest live-action stars in the 1940s and '50s, appearing in "Song of the South" and "So Dear to My Heart" and portraying Jim Hawkins in "Treasure Island." In 1950, he received an Academy Juvenile Award for outstanding performance in feature films and three years later he provided the voice for the title role in the Disney animated movie "Peter Pan."
Driscoll began experimenting with drugs at age 17, becoming hooked on heroin, and was arrested for the first time in 1956 for possession of marijuana, but the charge was dismissed. Late in 1961, he was sentenced as a drug addict and imprisoned at the Narcotic Rehabilitation Center of the California Institution for Men in Chino, Calif. He was released in 1962, but couldn't find any roles and eventually ended up in New York City working with Andy Warhol's art collective The Factory. He disappeared in late 1967 or early 1968, with two boys playing in a deserted Manhattan tenement eventually finding his body on March 30, 1968, about three weeks after his 31st birthday. His cause of death was determined as heart failure caused by advanced hardening of the arteries due to his longtime drug use. With no identification on his body, his remains went unclaimed and he was buried in an unmarked pauper's grave in New York City. His identity was only discovered about 19 months later due to a fingerprint match.
