ADD/ADHD most certainly exists. ZK has it right, and it being labeled a "disorder" is a total misnomer. There are a ton of positive aspects to having ADHD, but of course, there are some very real challenges that arise in traditional school and work settings especially. People think ADD is all about attention. Actually, that is a very small piece of it. The aspects of ADD that cause the most significant problems for people are executive functioning challenges- like impulse control, and managing overwhelm. Unmanaged ADHD and addiction is EXTREMELY common, especially with stimulant addicts. People with ADHD brains' produce less dopamine, stimulants release dopamine, that's why they're prescribed to treat the disorder. That being said, and speaking from personal experience that most of us can relate to- Adderall is totally whack. It doesn't matter if you have ADD or not, taking amphetamines regularly is not a good idea. I've taken other drugs for my ADD and NOTHING affects me the way Adderall or Concerta does (the amphetamine-class drugs) Other drugs actually slow my roll and curb my symptoms without making me feel like PCP superman. The sad thing is that abusing stimulants amps up natural symptoms of ADD, as it takes a while for your brain chemistry to resettle.
