Coming from someone with ADD and is currently on meds, I find it a little irritating that others are using it to make up for their laziness.
Having said that, I don't think it's that big of a deal. While it is irritating to me personally, what others do or don't do has no other tangible effect on me. All I can ever really ask for is a treatment to help me concentrate on daily tasks and calm the chatter in my head so I can study, plan, organize, learn. If other people are taking it to stay up and cram all night then so be it. A lot of you are saying that it gives them the unfair advantage, and I can see where you're coming from. On the flip side, is the ability to cram really well an advantage? The drugs put someone like me on a normal functional level, and so the argument is that they must take people who don't need them to some higher level of functioning beyond what they are normally capable of. I just don't see that as valid reasoning.
