How many days before ct scan (for head-routine and sinuses ) shall a person not to smoke cigarette & weed inorder not to be founded & interfere result?

Don't understand ?: there is no way that a CT scan can determine whether someone had cigarettes or weed prior to the testing, unless the smell is on your clothes/hair/breath and the technician tells on you, or you smoke it inside the machine. They can often tell if you are a smoker because of the acute and chronic changes in your tissues (not always though). It doesnt interfere with the results

Saw my ENT after CT scan. She showed me my sinuses and then she showed me a round solid grey circle. Was that top of head? She said it looked fine to.
Would a CT scan of my head for an unrelated reason have shown cancer of the sinuses? Or would that require a completely different CT scan?
