Hey all. Last used vyvanse 20 or 40mg few days ago. Was taking daily. Dont smoke weed but friends in the car were smoking last night. Windows were open but I got exposed I think got a whiff. Worried I got high. Am I going to fail an employment drug test? Freaking out. Do I need to take Herbal Clean Qcarbo ? Thx for ure help !
