Can a urine,drug screen detect,the levels of my prescription vyvanse (lisdexamfetamine) all month or just detect that the drug is,there?

Only the presence: urine drug levels do not generally accurately reflect the blood levels (and even less so the brain levels) of any drug. Most of the time, drug tests look for metabolites of the drug, many of which are not even pharmacologically active. So, while they can say that you had a substance on board, they cannot say with any accuracy that you are on a low or high dose, or the right dose.
