Thanks for the ideas.

I think I found a theme for the shirts. My brother wanted his to be "Legalize Freedom" with a pot leaf, so I thought it would be cool to do a bunch on this theme. So far I have:

"Legalize Freedom"
"Legalize Peace of Mind"
"Legalize Happiness"
"Legalize Healing"

But I want to do 6 shirts total, so I'm 2 taglines short. Any ideas to fit in with the theme?
