What would you do if.....?

What would you do if you found a couple pills in a ziplock bag that obviously belonged to your spouse and you had no idea he was even taking strong anxiety medicine?

UPDATE: I wasn't too clear in the post. I just wanted to see what y'all would do. I wanted to mention that I take anxiety meds myself but was prescribed by a doc.... the pills I found was apparently given to him by his sister who is a nurse (she had the meds at home). Neither her or my husband very told me about them. He was hiding them because he knows those pills are addictive and strong and should not be taken unless a doc prescribed to him. I'm scared he is just taking random pills for a temporary relief. Also he was standing in the room when I found them. I addresses it calmly and kinda laughed but walked out thinking "how could he keep a secret from me". I feel like I was too passive about it. Thanks y'all! Y'all are great!
