Supposedly ritilan is not very soluble in water. If one were to make a suspension of ritilan and nasal saline solution would this work as well as snorting ground ritilan (hard on the nose)?
Saline is just water with salts in it so I guess im not sure what your trying to do here. I think the majority of the chemical may end up running down your throat or out your nose?
Adding a little alcohol to a water based plug would work. But alcohol irritates soft tissue so this could cause discomfort and problems.
methylphenidate is extremely soluble in water. hence why people leave concerta pills in water or methylphenidate is prepared to be used for iv administration.
Ritalin is methylphenidate hydrochloride, which is exceedingly water soluble, think more than 50mg/ml. The pill fillers, of course, don't dissolve as they are meant to just be inert bulking agents.
