How is weed bad?

It's just so confusing to me how something like weed, that's an organic pain reliever, can be considered a schedule one drug. How it's above, or more dangerous than heroin or cocaine. I also don't see how our world got to the point where someone who grows or eats or smokes a natural thing, that's in no way harmful to your body, gets in the amount of trouble they do. I can't believe us as United citizens who have the right to choose, especially if it's in no way harmful to your body, let this nonsense get this far. No one should have to go through the amount of wasted time and energy that thousands of people have had to go through because they live how they see fit for the heath of their body and their mind. It's time to say, "enough is enough"! I will no longer be told how to treat my body and mind by someone who doesn't live my life, I know what's best for me better than anyone else thinks they do.
