Can anyone tell me if a smaller round white pill with no lines/number/letters on it is a 2mg. generic or brand xanax? I've looked on this site, called poison control, and a pharmacist. All said none exist that look like that. Thing is, they are supposed to be 2mg. xanax. Makes me wonder where and how they go in my boyfriends medicine cabinet, he said he is not sure what happened... Can anyone assist? Thanks
