The New Tuskegee Airmen?

From ABC News, a horror story:

[Former US Army sniper James] Elliott, 38, of suburban Washington, D.C., was recruited, at $30 a month, for the [anti-smoking drug] Chantix ... study three years after being diagnosed with Post Traumatic Stress Disorder. He served a 15-month tour of duty in Iraq from 2003-2004.
Months after he began taking the drug, Elliott suffered a mental breakdown, experiencing a relapse of Iraq combat nightmares he blames on Chantix.
"They never told me that I was going to be suicidal, that I would cease sleeping. They never told me anything except this will help me quit smoking," Elliott told ABC News and The Washington Times.
On the night of February 5th, after consuming a few beers, Elliott says he "snapped" and left his home with a loaded gun.
His fiancee, Tammy, called police and warned, "He's extremely unstable. He has PTSD."
"Do you think that he is going to shoot or attack the police?" the 911 dispatcher asked.
"I can't be certain. I don't know," she said.
"He was operating as if he was back in theater, in combat theater," she told ABC News. "And of course, a soldier goes nowhere without a gun."
When police arrived, they found Elliott in the street, with the gun in the front pocket of his hooded sweatshirt.
"Are you going to shoot me? Shoot me," Elliott said, according to the police report.
Police used a Taser gun to stun Elliott and placed him under arrest.
It wasn't until three weeks later that the Veterans Administration advised the veterans in the Chantix study that the drug may cause serious side effects, including "anxiety, nervousness, tension, depression, thoughts of suicide, and attempted and completed suicide."
The VA's letter to the veterans, on February 29, 2008, followed three warnings from the FDA and Chantix' maker Pfizer, that were issued on November 20, 2007, January 18, 2008 and February 1, 2008.

Chantix is one of the drugs being used in an estimated 25 clinical studies using veterans by the VA.
