Why do I start to see this pattern, where a non Christian will search the internet, and find some radical crackpot internet preacher that that's often unnacountable to a peer review or outside criticism, and post the nonsense in a forum as if it's the majority position, or even according to scripture?

Look, it's as simple as this:

" 29And God said, Behold, I have given you every herb bearing seed, which is upon the face of all the earth, and every tree, in the which is the fruit of a tree yielding seed; to you it shall be for meat.

30And to every beast of the earth, and to every fowl of the air, and to every thing that creepeth upon the earth, wherein there is life, I have given every green herb for meat: and it was so. "

Is marijuana a plant? yes.
Is it green? yes.
Does it bear seed? yes.

Marijauna is a gift from God. But that doesn't mean everything about the marjuana culture is right with God. Also, since God said we can have the herb, then that overrides mans law. So it's not unlawful and therefore it's silly to use it in any act of rebellion or act of counterculture.

I think common sense tells us quite plainly, that this plant was intended for consumption in moderation. There you go. Now use it in the healthiest way you can and praise God for giving you the wonderful herb.
