Damn. Sounds like for most of you guys this effect is a good thing. It's not necissarily a bad thing for me, but I usually have nice dreams (or interesting in any case), so I'd like to remember them more often.
A friend of mine has been reading some books on lucid dreaming recently and he's planning on sending them to me some time soon so that should be interesting to see if I can induce lucid states even while smoking regularly. I'd have to guess that it wont be easy since I'm not good at inducing lucid dreams anyway.
