Abstain from taking adderall for 3 days and it clears your system. Do not tell the people that you use adderal because they may do to you what they did to me. I was told that because I was on adderal I would get the job but, I would have to have someone follow me around because They wanted to be sure I could pay attention and do my job before letting me go on my own. Would you want to invest money and time into someone that needs a drug to function? Me neither so just quit taking your magic pills for a few days because amphetamines clear the system in no time and the amphetamine content in thm is low compared to METH. Oh and about the weed unless it was within the last 3 weeks don't even sweat it.
