The good news (or disappointing news, depending on how you look at it) is that the oil, when applied to your skin doesn’t penetrate the bloodstream. So no, it is really unlikely that you will feel the euphoric effects of the THC. You might feel more relaxed, your arms and legs may feel a little loosey-goosey, but that is an after-effect of any good massage.
Technically speaking, its THC—the cannabinoid that gets you high—which is illicit. When you take a drug test, the aim is to detect THC in your body, not “cannabis.” If you possessed weed without any THC in it, technically you wouldn’t be in violation of the law. Because “weed” without THC has a different name: hemp. And the rules governing hemp are quite different from the restrictions placed on cannabis.
