Will taking lorazepam change the effects of Adderall?

Well Adderall is a CNS stimulant, which is what gives you the speedy feeling. Lorazepam(Ativan) is a CNS depressant. It calms you down. Lorazepam's a downer and adderall is an uper. So if you take the two together, you won't get the adderalls full effect.
