This is idiotic. I used to overload strawberries with about 10-15 packets of aspartame to slake my sweet tooth (I now use the same amount of Splenda) and I never got high. Is there ANY credible study that this does something, or is this just a psychosomatic high?
It's probably some placebo effect, like your mind is saying "You're snorting some powder, so you're gonna get high, no matter what kind of powder it is".
