VIRGINIA BEACH — Every morning on her way to work, Kathy Fee holds her breath as she drives past the squat brick building that houses Dominion Psychiatric Associates.

It was there that her son, Richard, visited a doctor and received prescriptions for Adderall, an amphetamine-based medication for attention deficit hyperactivity disorder. It was in the parking lot that she insisted to Richard that he did not have A.D.H.D., not as a child and not now as a 24-year-old college graduate, and that he was getting dangerously addicted to the medication. It was inside the building that her husband, Rick, implored Richard's doctor to stop prescribing him Adderall, warning, "You're going to kill him."

It was where, after becoming violently delusional and spending a week in a psychiatric hospital in 2011, Richard met with his doctor and received prescriptions for 90 more days of Adderall. He hanged himself in his bedroom closet two weeks after they expired.

The story of Richard Fee, an athletic, personable college class president and aspiring medical student, highlights widespread failings in the system through which five million Americans take medication for A.D.H.D., doctors and other experts said.

Medications like Adderall can markedly improve the lives of children and others with the disorder. But the tunnel-like focus the medicines provide has led growing numbers of teenagers and young adults to fake symptoms to obtain steady prescriptions for highly addictive medications that carry serious psychological dangers. These efforts are facilitated by a segment of doctors who skip established diagnostic procedures, renew prescriptions reflexively and spend too little time with patients to accurately monitor side effects.

Richard Fee's experience included it all. Conversations with friends and family members and a review of detailed medical records depict an intelligent and articulate young man lying to doctor after doctor, physicians issuing hasty diagnoses, and psychiatrists continuing to prescribe medication — even increasing dosages — despite evidence of his growing addiction and psychiatric breakdown.

Very few people who misuse stimulants devolve into psychotic or suicidal addicts. But even one of Richard's own physicians, Dr. Charles Parker, characterized his case as a virtual textbook for ways that A.D.H.D. practices can fail patients, particularly young adults. "We have a significant travesty being done in this country with how the diagnosis is being made and the meds are being administered," said Dr. Parker, a psychiatrist in Virginia Beach. "I think it's an abnegation of trust. The public needs to say this is totally unacceptable and walk out."

Young adults are by far the fastest-growing segment of people taking A.D.H.D medications. Nearly 14 million monthly prescriptions for the condition were written for Americans ages 20 to 39 in 2011, two and a half times the 5.6 million just four years before, according to the data company I.M.S. Health. While this rise is generally attributed to the maturing of adolescents who have A.D.H.D. into young adults — combined with a greater recognition of adult A.D.H.D. in general — many experts caution that savvy college graduates, freed of parental oversight, can legally and easily obtain stimulant prescriptions from obliging doctors.

"Any step along the way, someone could have helped him — they were just handing out drugs," said Richard's father. Emphasizing that he had no intention of bringing legal action against any of the doctors involved, Mr. Fee said: "People have to know that kids are out there getting these drugs and getting addicted to them. And doctors are helping them do it."

"…when he was in elementary school he fidgeted, daydreamed and got A's. he has been an A-B student until mid college when he became scattered and he wandered while reading He never had to study. Presently without medication, his mind thinks most of the time, he procrastinated, he multitasks not finishing in a timely manner."

Richard Fee initial evaluation

Feb. 5, 2010

Richard began acting strangely soon after moving back home in late 2009, his parents said. He stayed up for days at a time, went from gregarious to grumpy and back, and scrawled compulsively in notebooks. His father, while trying to add Richard to his health insurance policy, learned that he was taking Vyvanse for A.D.H.D.

Richard explained to him that he had been having trouble concentrating while studying for medical school entrance exams the previous year and that he had seen a doctor and received a diagnosis. His father reacted with surprise. Richard had never shown any A.D.H.D. symptoms his entire life, from nursery school through high school, when he was awarded a full academic scholarship to Greensboro College in North Carolina. Mr. Fee also expressed concerns about the safety of his son's taking daily amphetamines for a condition he might not have.

"The doctor wouldn't give me anything that's bad for me," Mr. Fee recalled his son saying that day. "I'm not buying it on the street corner."
