Normally my wife and i talk 3 times a day if not more. So tonight when she finally called she was slearing her words very bad. Is there a way she can be drug tested asap

Absolutely! You have a right at any time your concerned for her treatment over medication or well being feeling that she's unable to act on her own behalf, the right to request she be taken to a local emergency room and evaluated medically for appropriate meds and appropriate dosages.

Yes they sell test kits at most pharmacies now
