The police opened his phone and went to his social media apps after Kade died in a bathroom at a Safeway Market. They found what they feared there.

Mr. Webb, a snowboarder and skateboarder who was about to give birth to his first child, bought Percocet, a prescription opiate, through a dealer on the social media platform. It was spiked with a lethal amount of Fentanyl.

According to preliminary numbers released by the Centers for Disease Control and Prevention, Mr. Webb's death was one of a record 108,000 drug deaths in the United States last year. Law enforcement authorities say an alarming portion of them unfolded the same way as his, from fake pills that teenagers and young adults bought over social media.

Morgan Gire, district attorney for Placer County, Calif., said that social media is almost exclusively the way that people get the pills. He has filed murder charges against a 20-year-old man, who pleaded not guilty.

The phenomenon has led to disturbing new statistics.

According to federal data, overdoses are the leading cause of preventable death among people ages 18 to 45.

According to a recent study in the journal JAMA, the number of teenagers who died from the drugfentanil has gone up from 25 to 884 in the next two years.

According to federal data, the rates of illegal prescription pill use are highest among people under the age of 25.

Drug dealers used pagers and burner phones to conduct business in the 1980s and 90s, but today's suppliers use social media and messaging apps with privacy features. Young buyers and dealers spot each other on social media and then communicate with each other.

The platforms have made it easy to get prescription drugs from anxious, bored customers and from those already struggling with addiction who were cut off from in-person group support.

Supplies of pills that have been pressed by Mexican cartels with chemicals from China and India have increased. Fentanyl is 50 times more potent than heroin and is cheaper to produce. 20.4 million counterfeit pills were seized by the Drug Enforcement Administration last year. According to its scientists, about four out of 10 pills contain lethal doses of Fentanyl.

The National Institute on Drug Abuse says that new waves of customers are quickly becoming addicted.

The D.E.A. identified 76 cases of drug traffickers who used code words on e-commerce platforms and social media to sell drugs. The agency has included a feature in its One Pill Can Kill public awareness campaign, a poster called "Emoji Drug Code: Decoded" with images of drug symbols.

There are drug sellers on every major social media platform, according to a professor at the University.

On August 15, 2020, a star high school football player from Mesa, Arizona, contacted a dealer through a messaging app, seeking a Percocet.

The dealer dropped off drugs around 3 a.m. as footage from the family's home security camera would show. He swallowed a pill and fell to the curb. A 15-year-old neighbor found him dead.

The ease with which dealers can evade detection is devastating to Wendy Plunk. She said she keeps an eye on the man who sold her son the fatal pill. He changes his name a bit when he gets kicked off, but he stays the same.

In January, parents of children as young as 13 who had died from pills protested in front of the headquarters ofSnapchat in Santa Monica, Calif., with signs accusing the company of being an accessory to murder. Laura Berman is a relationship therapist and television host. Sam, her 16-year-old son, died of a drug overdose in February of 2021.

Facing criticism from law enforcement and grieving parents, social media platforms have been redirecting drug seekers to addiction services.

The Ad Council announced a campaign on Monday that will be funded by three tech companies to alert teenagers and young adults about the dangers of Fentanyl. landing zones for the warnings are expected to be provided by social media platforms.

Drug exchanges are being interrupted by the parent companies ofSnapchat and Meta. In the United States, from July to December last year, it took action on 144,000 drug-related accounts. The figure does not include the 88 percent of drug-related content that was pre-emptively detected by artificial intelligence software.

The results are blocked when users search for drugs. There is an in-app video channel with content from nonprofits and the C.D.C. that addresses the dangers of prescription drugs.

Four million drug-related exchanges were taken action by Facebook in the fourth quarter of 2011. There were 1.2 million figures which represent both users and pre-emptive detection technology.

An offer of help and an automatic warning were set off by a recent search for Percocet. The account that posted photos of the pills and contact information with phone numbers on the messaging apps was one of the many results.

Many sellers move to another platform when dealers are removed from their platforms.

We detect about 10,000 new drug related accounts a month.

Drug use has increased as mental health has deteriorated among young adults and teenagers. Experts in adolescent behavior say that young people tend to avoid heroin because of its addictive properties and because of a fear of needles. The false imprimatur of medical authority appears to make pills safer. prescription medications have become normalized for anxiety, depression and focus in their generation.

Ed Ternan said that by the time the kid goes to college, his friends all have prescription bottles in their backpacks. Charlie was dead from poisoning thirty minutes after ingestion.

Mr. Ternan and his wife asked the company to step up monitoring after Mr. Ternan's death.

I said if the kids were buying real Percocet they wouldn't be dying. Mr. Ternan said that you need to escalate this problem to the same level as child sex traffickers.

Song for Charlie is a group of families who have lost children to drugs. Mr. Ternan met with federal officials and connected them with digital and drug treatment experts. His group creates cautionary content.

Mr. Ternan said that the rules of engagement in the war on drugs have changed. We need a more collaborative approach between Big Tech and the government.

Morning Consult was commissioned by Snap to conduct a survey of drug knowledge. The results of a random sample of 1,449 users of the messaging app show their vulnerability to misuse of prescription drugs. They said they were overwhelmed, anxious and depressed, but also fearful of the stigma surrounding mental health challenges.

Only half of the respondents knew that the drug could be in fake pills. When asked to rate the danger posed by certain drugs, nearly two-thirds were likely to rank heroin and then cocaine as extremely dangerous, but barely a third put fentanyl in that category. 35 percent of adolescents didn't know enough about the danger level of the drug.

Wendy Thomas, a substitute teacher from North Carolina, used her grief over the death of her son from a counterfeit Percocet to reach teenagers. Matthew's Voice has written health-class curriculums about the drug Fentanyl for high school freshmen and seventh- graders that are currently under final review by a large North Carolina school district.

It motivates anguished parents like Elizabeth, who is Kade's mother and the grandmother of his newborn daughter.

Ms. Dillender has taken her campaign to a number of social media platforms.

Laura Didier is a mother from Rocklin, Calif. A year before Mr. Webb died, his former husband found his son dead in his bedroom. He bought a Percocet from a dealer on the app.

If there is a problem, you will see red flags; their grades are dropping, their disposition is changing, and their friends are changing. Without your ability to predict, this can happen very quickly. I don't want families to think that it can happen to them.

The Santa Clara Opioid Overdose Prevention Project in California is promulgating a warning aboutFentanyl.
