Could My Body Naturally Produce Temazepam When I Have Never Taken It But Was Tested Positive?

I tested positive for a drug called temazepam I’ve never heard of that drug in my life I take suboxone that’s it i retested again 2 weeks later and tested positive for this drug I’m really confused is there any way your body can prcodice this drug naturally or could it be something I’m eating? This is stressing me to the max I need to figure this out
