First of all, these people can't even get their terms straight. The first two sentences in the "It's just a Plant" link are fucking laughable. "they use the dried leaves of the plant called Cannabis Sativa."? Last time I checked, "Cannabis Sativa" was only one type of cannabis that you take. There's also that Indica and (sometimes) Ruderalis. Seriously... I'm laughing, not crying, at this.
