Why does your blood have no opium if you are taking opium?

Answer 1

opium is a latex mixture of alkaloids such as morphine, codeine and thebaine just to name a few. opium is therefore a mixture and when you take opium these drugs are metabolised into compounds such morphine. This means that if they gave you a blood test they would find morphine and other things on the same lines of that but not opium as opium is a mixture of drugs not an actual individual drug
