Try making something like cannacaramels (linked in my siggy) which will give you a background and make your smoking high MUCH longer, trippier, and stronger.

MTF keeps me high for hours still, with visuals. It's a bit much for me... lol! I did a cross of that to White Rhino that I've nicknamed 'Foxy's Rhinofuck' for now, and had people COMPLAIN that it is too strong to be fun. One guy I gave cuttings to just got off opiate painkillers (morphine) for a back injury by smoking the shit, and is like, "um I think I am ready to go to something a lilttle gentler now", haha.
