The_cat, there are actually multiple studies (easily found on google) that have found that children/adolescents with ADHD who are treated with stimulant medications are far less likely to abuse drugs or alcohol in their lifetime versus children/adolescents with ADHD who are never treated with stimulants. People with ADHD who are not being treated tend to make more impulsive decisions (a symptom of ADHD) and tend to self medicate with drugs and alcohol. ADHD medications should never make you “feel” differently. If they do, then they aren’t on the right medication. I treat kids with ADHD and I always ask them “do you like your medication, don’t like it, or don’t care?” I want them to say (and they almost always do say) “I don’t care, I don’t notice anything since I’ve started the medicine.” But when I ask parents and teachers, they should all say “we have noticed big positive changes in behaviors.” If I ever hear a child tell me they feel different in some way or do not feel like themselves, that is the first sign to me that they are not on the right medication or dose. Most medical providers do not have good experience with ADHD and are either not diagnosing correctly, or not prescribing the right medications. But when a good, thorough diagnosis is made and the right medications are prescribed at the right doses, these medications can make significant positive changes to a child’s life. Stephen Gilbert, I hear you about not giving meth to kids. Adderall, Ritalin, “speed,” and “meth” are all forms of stimulants that are ‘essentially’ the same thing. However, so are caffeine and nicotine. One could argue that Adderall/Ritalin are as closely related to speed/meth as caffeine is related to speed/meth. Caffeine is actually found to be much more addictive and with more severe side effects than Adderall/Ritalin when prescribed at the correct doses to kids that actually have ADHD. This study is great and a follow up is very needed. These medications can have many negative side effects, but can also be essential in a child’s social and academic success, again, when prescribed correctly.
