We're arguing about the semantics of rush again...
If you think you(or they) are experiencing a rush from snorting, IV it to find out what a real rush is.
People need to stop saying "rush" in regards to any other moa besides IVing and smoking. It's just misleading.
Edit: By definition, a rush is caused by the immediate BBB penetration of a drug and the quick saturation of receptors. Any other moa besides IV/smoking requires time for the drug to be absorbed, and therefore the BBB cross is much more slower and gradual. Look into the pharmacokinetics of various moa's if you still don't get it.
Edit: Bolded text for emphasis.
