In Vietnam, it is most commonly smoked after a meal on a full stomach to "aid in digestion", or along with green tea or local beer (most commonly the cheap "bia hơi"). A "hít" of thuốc lào is followed by a flood of nicotine to the bloodstream inducing strong dizziness that lasts several seconds. It should be said, however, that even heavy cigarette smokers have had trouble with the intense volume of smoke and the high nicotine content, and that side effects include nausea and vomiting.
