Here is a thought that I have been mulling for years but have never acted upon. You can make a hemp/hops graft onto a pot plat. I have heard that pot is similar to hops and the hops will graft easily onto the pot plant. The hops that results is supposed to be stony like weed.

This is really old information and could even be a myth. But a little research should tell you if the info is accurate.

If this works you should be able to make really stony beer. If not just add some tincture, oil or keefe just before bottling. The tincture is probably the best way to infuse beer with thc.

Let us know what you find and if you can find any info on grafting hops onto marijuana.
