How long does it take for 30mg adderall to kick in?

To tell you the truth it matters what kind of form the pill of Adderall it is. IR or instant release stays active in your system for 5 to 6 hours, these are the pills that are pink or orange depends who makes it. Adderall XR or extended release dissolve in your system two types of ways. One part of the pill acts fast while the other part is time released and the time release stays active in your system for up to 13 hours. For good measure use the quick release pills if available because they act quickly and only for a short period of time. The longest I have stayed awake is 4 days and I was so sleep deprived I just crashed on the fourth day. But if you just snorted 30mg of Adderall you can be awake for two days easy, especially if your body is not used to it. I hope that answers your question.
