Pretty much what FALLout said. Except, to answer your question, when you're using a vaporizer the heater isn't actually hot enough to burn the weed, it's just hot enough to vaporize the THC in the weed, so there shouldn't that much smoke. So, it shouldn't smell. If it does smell though, it wont be like weed.
