I'd advise not to smoke weed again while experiencing DP. Around a year and a half in of having DPD, things were starting to look up for me. I was feeling better, I was able to forget about DP sometimes, and I wasnt constantly spaced out and afraid like I previously once was. One night I got pretty cocky and decided I was going to try and smoke again for old times sake with some friends. I thought "hey I'm feeling so much better, I know how to beat DP! I'll be fine. My DP is basically nonexistent now so screw it!" But man, was I horribly mistaken. I took around 3 hits and I was back at square one. Intense panic, feelings of impending doom, extremely fast heart rate, basically everything I had during the first panic attack that set it off. For the weeks that followed after, it seemed as if all the progress I had gotten had dissapeared completley- almost as if my brain had somehow forgotten how to cope with DP. Here I am around a year later and I can safely say I'm around 98% recovered with only a few minor symptoms here and there. I fully believe that if I never smoked again that night a year ago I would have arrived at my current state of mind much quicker or maybe even have been 100% recovered. Who knows, all I have left to say is, please respect the drug that may have caused your DP in the first place. If you're going to smoke again, keep in mind the risks that could very well make your DP even worse or set you back in recovery. Who knows, but it's your call.
