One of the inactive ingredients in generic bupropion pills is hydrochloric acid. People abusing this antidepressant through I.V. administration sometimes report a very intense burning. For the people that know chemistry; could this be caused by the hydrochloric acid, or is bupropion itself a corrosive substance? Also, has anyone tried lowering the pH of the IV solution before injecting? (We all know the dangers of shooting pills, please no flaming).
