Where'd that ADD thing come from? You mean shit like Adderall or Ritalin? I know a few people on the stuff. Let us refer to wiki, but if you don't care for that shit, I'll summarize what I gleaned from it below:
Effects
Amphetamine, both as d-amphetamine (dextroamphetamine) and l-amphetamine (or a racemic mixture of the two isomers), is believed to exert its effects by binding to the monoamine transporters and increasing extracellular levels of the biogenic amines dopamine, norepinephrine and serotonin.
It is hypothesized that d-amphetamine acts primarily on the dopaminergic systems, while l-amphetamine is comparatively norepinephrinergic. The primary reinforcing and behavioral-stimulant effects of amphetamine, however, are linked to enhanced dopaminergic activity, primarily in the mesolimbic DA system. Amphetamine binds to the dopamine transporter (DAT) and blocks the transporters ability to clear DA from the synaptic space.
So it allows more dopamine to remain in a neural system or what-have-you. At least, I am led to believe this. More dopamine means more neurotransmitters, so...that'd be good, I assume?
So if one took enough Adderall or other amphetamine, one could extend their abilities to concentrate? Sounds like a good enough reason for college kids to try to buy/sell the stuff. But is an ability to focus on things that seem boring in a "natural" state a 'complete shift in personality and who' you are? Well it does affect your brain, and I believe that's where shit goes down (none of that spiritual stuff), so yeah, I guess you can be changed by pills.
My friend, who takes Adderall in specific on a daily basis, knows he changes. He accepts his change, however, because he is noticeably more enjoyable while on the medication. He's better in school and much more alert and witty. He's a changed person with the medication. He knows this and when I asked about it once, he said he didn't mind the possibility of two personalities and such. He did a little fight club thing, saying the natural him was "jack" and the adderall him was "Tyler Durden," the image of improvement in a platonic sense. He reasoned as such:
If Jack knows that taking the pill will change him to Tyler, why does he continue to do it? Doesn't he want to preserve his existence? Well, Tyler's a deal smarter and more capable than Jack, and Jack enjoys those weekends when his work is already done because Tyler's quite productive. So Jack takes the pill, knowing for a while he will be Tyler, but he'll be productive for a bit, and sooner or later, he'll be back to Jack because you can't double-dose without serious health risks, so Tyler won't take the pill to preserve himself.
I think it's a mutual interest between these two hypothetical persons...I don't doubt the situation exists on a level, just not as extreme as one could imagine after seeing "Fight Club". Their mutual dependence on each other is what also makes their life as a whole a more enjoyable experience. By accepting that change, life has improved for him. And who knows? Some say you grow out of ADD, so perhaps he may find himself a bit less like Jack and a bit more like Tyler every day until the two are balanced out.
My friend and I have very odd conversations.
