you mean like dissolving ritalin on water and then putting that up the nose?
well technically it should work.
i did it last week. i dissolved 40mgs of ritalin in a few mls of water, filtered with cotton, and put the solution in my nostrils with an eye dropper. i felt a bit of it.
i bet it's effective, at the time i did it i have a tolerance (was snorting up to 60mgs every day last week) to ritalin so even 40mgs snorted would do little.
