adderal shud enhance it cause like some1 said ritalin is basically speed and so is adderal so itll speed u up like a meth or coke high if u take enough. the reason its used for add and adhd even though its speed so that doesnt seem to make sense is because at low doses it calms people with add down (i think its because with a mild dose it increases anxiety, which is one of speeds effects, but it doesnt speed u up til u take more so the anxiety helps people concentrate...i think)
