Uhh, Im going to go ahead and say no for this one man. I've tried that, and honestly, doing drugs while trying to Lucid Dream is a complete mess. I mean, as far as nootropics, you should be good, but for the illegal stuff nah. It messes up your focus and I know weed and Lsd made my dreams go crazy. Then again, thats just my experience and I'm not everyone soooo. Treasure your brain though man, thats what gives you dreams. If you mess your brain up you mess your dreams up in a way too im sure.
