If coffee makes you too jittery, this may be the right brew for you: single-serve coffee pods infused with high-grade cannabis oil. House of Jane's Jane's Brew promises a cup of joe with a side of pain and stress relief. There is also a line of infused flavored creamers.
Update, May 29, 2015: Keurig objects to calling the cannabis-laced brew "k-cups," although House of Jane markets them that way. Those references have been removed from the video and post.
