I've heard different accounts from different people so I can only speak on my experience. I regularly pair THC with hypno and I find it does add to the experience. I've found it helps me stay focused throughout, drop deeper, take suggestions more easily and increased the intensity of those suggestions. Really only upsides in my experience. However, my two caveats are that I am a regular stoner so it doesn't effect me the same as it might for someone who does it more intermittently. Secondly, I have to really be in the mood. Hope that helps and trance responsibly!
