Could i smoke canola oil with a vaporizer?

For what purpose?: the propellants that are used in e-cigarettes are mainly propylene glycol, which is an oil, whose safety when inhaled has not, to my knowledge, been demonstrated in any studies. Even more so with canola oil. People who are willing to smoke, inhale, snort or inject virtually anything are people with significant underlying psychological and/or psychiatric issues, and you need to get help asap.
