The plant is called "Thuốc lào" in Vietnam, and 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 "rít" of thuốc lào is followed by a flood of nicotine to the bloodstream inducing strong dizziness that lasts several seconds. Heavy cigarette smokers have had trouble with the intense volume of smoke and the high nicotine content; side effects include nausea and vomiting.
