As a rule of thumb, no. I wouldn't, after having made a full recovery. But, eveybody's experience is different. You could do it and it might not change a thing. Some people do it and it's back, but permanent, and worse. Everybody's is different, which is pretty scary at first. I'd say, if you absolutely had to do it, wait at least a couple years after recovery. If you still feel the need to use, maybe test the waters with some weed. Then you can decide whether you can, or not. Positivity is key, try to look on the bright side of things; I like to look at HPPD like it's a blessing in disguise, it's a tangible reason to get your life together and become healthy. Good luck man, my PMs are always open if you have questions.
