Many of my best philosophical ponderings occurred when influenced. Theories on the mechanics of love, nature of the universe, karmic evidence, natural laws, the fabric of reality, cognition and awareness, the soul and it's relation to consciousness... good stuff. Back when I smoked herb that's why I did it (well sometimes, many times it was just social lol). I'd prepare by meditating and focusing on how I wanted to direct the high, and I'd have a notepad nearby (even though mostly I forgot to use it lol).
The worst is remembering that you discovered something amazing whilst you were gone, but not being able to remember what it was LOL (perhaps it only seemed amazing because you were gone, but then again, it could be the next post-it-note, or big theory on space-time and you wouldn't know cuz you didn't write it down).
I had something like that happen to me and it bugs me to his day (it was when I was 10 years ago). It had something to do with music visualization and a new notation system. It was supposed to be perfect for finding harmonies and beat frequencies in chordal tones. BUT I CAN'T REMEMBER IT CLEARLY!!! =P =)
