Frankly, I agree with this article. Unless the illegal users above have a doctorate in Medicine they have no right to tell you that these substances are not dangerous. Any drug, prescribed or illegal that has such a dramatic influence on the brain must be taken with caution. Nobody knows the long term effects of these drugs. Though they seem like a miracle cure for those who suffer from ADD or ADHD for those of us who do not have these diseases the drugs mess with brain chemicals that were not "broken" to begin with. Time management and some motivation will help you study for that test or write a long paper, most college students (or at least half) do not take these drugs and they manage to do just fine!
