Same for me. When I first started smoking I had no anxiety what-so-ever from weed. It made me feel relaxed, hungry, things seemed funny, it was nice. This lasted for several years. After taking a break and returning to it, I first started to experience paranoia from it. This went away after continued use as my tolerance came back, but it is worth noting that I did not have such paranoia when I started smoking in the first place. I find that when I take any significant break, even of a week or two now, that when I start up again I get bad anxiety. These days it seems to come and go in waves. Sometimes I can smoke a ton of weed and just enjoy the experience. Other times smoking small amounts causes extreme paranoia. I have somewhat come to even like the paranoid trips it gives me though. Mind racing at a million miles per hour, but when taking control of this + the increase in abstract thinking and creativity it can be like a super smart drug for me, at least it seems so when I am in such a state of mind . I took some orally and it was to much though, it caused me to shake violently + paranoia , never had shakes before. So yeah it is hit or miss for me, sometimes relaxing and fun, sometimes my mind races but I can channel that energy in a pleasant way, and sometimes I am extremely paranoid and violently shaking and absolutely hate the experience. But I take the chance still and smoke on occasion, sometimes regularly and sometimes with months in between sessions. The more often I use the less likely I am to have unpleasant experiences. Sometimes I get entirely lost in my mind after I smoke and my body goes almost completely on autopilot while I am quite literally stuck in deep thought. Weed actually makes it much easier for me to entirely filter out the external world and enter into my mind and thoughts, to the point that it is actually difficult to 'escape' from thought to pay any attention to / interact with my surroundings. This coupled with racing thoughts can be an amazing experience though, laser focus on train of thought that goes at a billion miles per hour is enjoyable for me, but does come at the cost of temporary near-total inability to interact with external stimuli.
