As long as I've vaped, I've sometimes found something lacking in the sensation, particularly with tobacco flavors, and it doesn't seem to be about nicotine or throat hit, and I don't think it's the mysterious MAOIs. It's more a matter of robustness of flavor. When you think of full flavor versus light cigarettes, it's the "tar" component, not the nicotine, that determines the taste and the sensation when inhaling, as I understand it. As somebody who didn't have any use for light cigarettes (although I did settle for Marlboro Mediums for quite some time), I sometimes wonder if juice manufacturers cater their products to the lights-smoking majority. And I wonder if those who were full-flavor smokers and who DIY tend to up the flavor component in their juices to good effect.
