A drug used to treat ADHD children is causing concern in the United States.
It is called Risperdal and it is supposed to be used primarily for adults with sever psychological problems.
But last year it was prescribed more than 6.5 million times.
The side effects include young males developing female sex organs.
Nineteen-year-old John was just seven when he began taking Risperdal for ADD.
Even though the FDA approved the drug only for adult patients who were psychotic, John's doctor and others widely prescribed it to kids for less severe behaviour problems.
Once taking Risperdal, John's mum says he became aggressive, sleepy, and developed bowel problems. But the biggest shock came when he was 14 and started developing women's breasts.
"He asked me if he was a girl," she says.
It turns out Risperdal can increase production of a hormone called prolactin, which stimulates breast growth. It is called gynecomastia
