Yeah, in my experience they didn't go together well either. The reason you're getting crazy vivid dreams a couple of days after you stop smoking, is because of rebound (or it's called something similar), and that's normal, then after a while your get back to normal.
When I used to smoke, I would have a really hard time remembering dreams... I would remember random scenes of a random dream maybe once or twice a week (nowhere enough for having LDs). When I stopped for a month a couple of years ago was when my recall increased a lot and I had my first LD. Now I quit for good about 5 months ago, and my recall has been averaging at 2 dreams per night.
What's for sure though, is that it varies for person to person. Overall, marijuana does affect dream recall in a negative way, which is in turn bad for LDing. However, it helps some people at night by relaxing them, which in turn could help with WILDing. It really just depends on how it affects you...
Good luck, and welcome to DV!
