Theres so many parents out there that drug up their kids (with drugs like ritalin and such), so they don't have to deal with them.
And theres many more that get their kids diagnosed with disabilities just so they can get an extra paycheck.
It's really sad.

Yeah, turning your kid into a zombie may sound like less hell, but is it really worth not knowing them? - Not truly knowing whats going on with them?
And it really doesn't solve the kid's problems. Drugging them only masks them.
Whatever may be the issue, whether it be school-related, family-related or something else entirely, that problem hasn't changed.
Its still there, only now your kid is too drugged up to show that it is there.

Also, what happens when they're taken off the medication?

Will the kid know how to take and handle their problems?

No.
Mostlikely, they'll try to find a way to go back to the way it was before, when the drugs did all the handling for them.
In the end, the kid will mostlikely turn to illegal drugs.

So, parents, ask yourself:

Have I really tried everything I could to find and fix whatever is causing my kid to act the way he/she does?

Is this pill really going to help my kid in the long-run?

Do I really care?

And heres a question from me.
How can you really call yourself a good parent when the medication is doing all the 'parenting' for you?
