There are computer-based tests for ADD as well. Those are more "objective" evaluations based on average performance of people with and without ADD. Depending on where you are, that might be easier or harder to get.

But let me disabuse you of the notion that ADD meds are always bad. They are a lifesaver for me. I could never have gone to graduate school without ADD meds - I now have my MS and am finishing a PhD. I sleep better when I take my meds, and am much easier to be around. I drive even myself crazy when I don't take them. It's the difference between practically disabled and absolutely 100% functional cognitively.

Meds aren't the answer for everyone, especially if they don't actually need them - then there's a much higher likelihood of dependency. But if you use them responsibly, there is a very low chance of addiction - and there are also non-stimulant types (Strattera). There's a huge black market for Adderall, and those jerks piss me off because they make it harder for those of us who need the meds, and there are shortages as a result of it being a DEA controlled substance. But for some of us, it's the difference between being a failure and living up to our potential.
