Got hauled to the school psychologist in elementary school for calling my teacher an idiot. Was prescribed Ritalin. My parents told them absolutely not and I've had a great life without it.
I'm sure there are some people who need these medications. But realize that the incentives of the system are to give you pills. It's not even as debauched as bribery or kickbacks -- it's simply that a person who studies psychoactive medications rather than parenting will, when asked to solve the problem of an unruly child, naturally come up with medications as the solution rather than alternative parenting.
