A drug with a long history of medicinal use and use by Americans has been revived with a new breed of drugs called Xanax, which is sold recreationally.
The revived drug has been described as an “anti-anxiety” medication and has been marketed as a way to treat anxiety disorders.
In addition to being recreationally available, Xanax can be bought online and is being prescribed by a doctor.
A 2012 study found that about a quarter of the 2,700 people who took Xanax between 1999 and 2010 suffered from panic attacks.
“We are trying to build an understanding of the way that Xanax works and what it can do to people,” Dr. Richard W. Gaskin, the executive director of the National Institute of Mental Health, said in a statement.
There is no evidence that Xanox can cause a serious illness, Gaskins said, and it is not known if Xanax is addictive.
Gaskins also said Xanax has not been proven to cause a heart attack or stroke.
“We can’t say that it’s safe to use,” Gaskings said.
Many people say Xanax relieves anxiety and insomnia.
While Xanax might help to calm anxiety, the side effects include headaches, insomnia and stomach cramps.
People who are already experiencing a panic attack are more likely to take Xanax.
Dr. David B. Kessler, director of Yale-New Haven Hospital’s emergency department, said people are increasingly taking Xanax as a “medicine of last resort.”
“It’s like a drug of last use,” Kessler said.
“And people have to take that medicine.”
The Food and Drug Administration has said Xanox has not caused a serious health problem.
However, it does not have the same regulatory protections as prescription medications.
An FDA official said the agency does not approve Xanax for prescription or over-the-counter use because Xanax remains a Schedule I controlled substance.
