Been browsing the forums for an answer, found things that relate to my question, but I'd very much value a direct response. I took 100mg of adderall at 12PM last night. He told me it was wonderful high, but that is beside the point. His friends want to do about 30 mg with himtoday, which would be roughly 12 hours after he injested the 100mg. He has never done adderall in consecutive days, so he does not know if this a bad idea. He is mostly worried about amphetamine psychosis. Is this safe for him? How long should he wait?
