Green Xanax Bar

The green Xanax bar is also a 2 mg version of alprazolam. This pill is supplied by Dava Pharmaceuticals. Unlike the yellow or white Xanax bars, the green Xanax bar only has two grooves dividing the bar into three sections. The pill imprint is S903, with the S on the left section, the 90 in the middle, and the 3 on the right section.
