I've done CBD by itself, it came in a straw in a honey matrix, perfect for dumping into a cup of tea , which I did.
There is no buzz what so ever, just a relaxing effect much stronger than Valerian Root and crap like that, but much weaker than a Xanax.
I'm also a registered medical card holder that smokes daily, and I find that too high of a CBD to THC ratio can leave me feeling like I didn't get high enough so I go through it quicker than high THC /low CBD smoke.
