Yeahhhhh. I've always been hesitant to try these free, natural things suddenly released out into the public. The sort of things that accomplish a result and effect that you otherwise wouldn't be able to achieve without dangerous substances in your system.

I'm steering clear and watching what happens. Having worked with some people who do it at work, I'm...on the fence.
It's not entirely certain what the long term effect is. The people who say with absolute certainty that it's harmless, even after decades of use...are the sort of people who dive with both feet, regardless of what body of water. To compare it to pot, is a little...bold, I think.
