How bad is it to eat glass?

I think my terrible wife put finely ground glass in my peanut butter sandwich. Will this cause me many problems inside of me? I tried to force myself to vomit but it didn’t work. I saw her using the peanut butter yesterday so I know she did something to it because I was like, I think I will make a peanut butter sandwich for lunch tomorrow’ out loud which was clearly a mistake on my part. How can I tell if there is glass in the peanut butter?
