Well For now I'm gonna start brainstorming the topics included.

Main topics should be something like:

Laws about Cannabis
Consuming Cannabis
Growing Cannabis
Maybe history? (i know most books already talk about history of cannabis, do you think it should be included?)

Then within each main Section with be smaller chapters:

Laws:
laws in your country
laws in your state
what you can do to change these laws
how to avoid being busted
what to do if you are busted for possession
what to do if your busted for growing

Consuming:
which way is healthiest
how to make your own pipe/bong
how to bake with cannabis

Growing: (both an indoor and outdoor section)
grow room set-up and design
fertilizers
propagation
vegetative growth
flowering
harvesting

Any more ideas?
