After I got my first e-cig, an itaste 134 on sale, I dissolved 0.5g DMT in 3g mint flavor 0mg nicotine e-juice. I was disappointed for the much weaker effect at first. Then I found out, if I inhale some more air to fill my lungs right after inhaling vaporized nicotine e-juice, I exhale almost no smoke immediately. I'm going to try this technique on DMT e-juice soon.
