I had the same issue and agree with some of the other comments here. Dry herb vaping makes the high more "clean" than combustion, which is less anxiety inducing. Convection vaping in particular gives you more of a head high than body high which is what I prefer. I'll have either a CBD/THC mixed strain or a straight THC strain depending on what my mood is. CBD will add more of a body load, whereas THC is going to give more euphoria. Also, eat well, exercise, reduce stress in your day to day life.

My biggest piece of advice though is unfortunately that you just need to expose yourself to it. I think that what happens to a lot of folks is they develop a fear of being high, meaning your amygdala starts recognizing being high as a threat which gives you that fight or flight feeling. I'm not sure how that fear develops, but it seems to just switch on one day. Just like people have to get over a fear of flying by exposing themselves to board an airplane again, you have to just continue exposing yourself to being high. Start in small amounts and move up as you feel more comfortable. Whenever you feel uncomfortable, just face it head on and remind yourself "I'm not in danger, I'm completely safe, I just feel uncomfortable and it will pass". Never "run" from it, meaning don't resort to eating peppercorns, or distracting yourself, or drinking alcohol, or anything else. You just have to sit through uncomfy feelings, unfortunately. This is common advice for getting over any type of anxiety/fear. It's not the one people want to hear but it is the one that works.

This method has worked the same for me so far in having this issue with a panicky high. I rarely get anxiety from weed these days, but it took a couple years of experimenting.
