>>11231975because nobody has ever put a human to sleep and dissected their brain after 1 month of adderral usage, like they did with the primates in the study. and there are humans for whom bupropion is euphoric, crush XR pills and abuse it, just search for it on the internet.
whether something damages your brain or not is not related to it being euphoric or not. cases where it causes permanent damage to the brain provenly exist. there is no study done where they examined the same properties of a brain and found no degeneracy after 1 month of "therapeutic" amphetamine usage.
