Deug testing.: If have legitimate prescriptions and reasons for taking these then you must be honest in providing this information to testing party. Ativan (lorazepam) has long half life, but i suggest be honest if their use is legit.

Varies: Medication list you provided are different, but to be safe, I should say that drug screen might be positive for as long as 6 weeks.

Blood and Urine Test: Percocet can be detected in the urine for 2-3 days; vyvanse (lisdexamfetamine) can be detected in the urine for up to a week; and, Ativan for three days in the urine. Blood levels of all three are undetectable after 2-3 days under ordinary metabolism and an intact p450 enzyme system.
