Yes it is possible; however, even in tablet form, most of the drug will be rendered completely inactive from first-pass metabolism (when liver processes it). Other than taking the dose parenterally, one could dry the liquid in the vials out on a hot plate and scrape up the remaining crystals and "insufflate" the powder or mix with water in a needleless syringe and "plug" the solution to get much better results than by taking orally.
Take care and be safe!
^i was dissolving pills, but i was using like 4-5mls of water. then just make sure you don't have to go to the bathroom, lay on your side, stick it an inch or two up there (not with a needled syringe, obviously), and squirt. stay on your side for 15 mins. further detailed in the thread i linked under "plugging."

^an error in assumption.im pretty sure most of the people here are involved in the "distribution of felony narcotics" on a daily basis
