The cartoon, and the following facts, are from a blog: http://newhaiti.wordpress.com/2010/05/16/hemp-for-hait/
Definitely worth reading the whole thing, but the gist is:
>hemp is a native, annual plant, can be used to make cloth (as opposed to cotton or flax, neither native to North America
>grows a s**t-load faster than trees, and can be used to make paper
>does NOT have the capacity to get anybody stoned,
>and doesn't require all kinds of chemical fertilizers and pesticides to thrive.
