you can snort any pills....lortab, xanax, ritalin, adderall, whatever
in my book, it's a serious addiction, but then i would think of it as a progression.....taking pills orally didn't work anymore, so you start snorting them....but other people may just do it that way to see what happens. i can't say your husband's reasons.
also, IN MY OPINION, i would think he is going to need help detox/rehab to get clean. that's a lot of drug use over a lot of years.
don't be upset if he can't do it at home, or even do it the first time. it may take lots of tries and lots of patience
good luck
