Hold that thought, because we haven't addressed the "can you" bit. It turns out a group of researchers think they can, courtesy of a new approach that involves using ultrasound to stimulate the scent-processing part of the brain. Indeed, they claim the technology can be used not just for smell but also as a highly efficient method for inputting data into the brain. Yes, really.
