make each issue about someone's stoner story.
Like that pizza call that Penguin made. Make an issue just on that.
If you want dark, then definetly go to the legal section and check out people's stories about getting busted or robbed or whatever.
Could easily become a legit comic if you did that because you are portraying real life situations.

I thought it was a dumb idea but then I realized how realistic our stories are and they could be made into a decent comic if done right.
