Sure you can take a Roxi 30 sublingually, but there's no point to it. Snorting will give you a faster onset--
better rush, and anything that doesn't get absorbed in your nose you can wash into your stomach by snorting some water. Swallowing a crushed up pill on an empty stomach will hit you the same as SL, and its is much easier, less time consuming. If you want, try it out and just be sure to swallow your spit when your done, its not as though the drug will be negatively effected by the enzymes or ph of your spit (I've looked into it

)
