tangsin — a mild, smoked drug popular throughout the Reaches, tangsin is a mixture of tobacco, ginseng, and the leaf of a hyoscyamine-containing plant. Tangsin tends to relieve intestinal and allergy symptoms in humans, elves, and half-elves. These effects are less notable in gnomes, halflings, and dwarves — but it is significantly beneficial in treating hypertension in gnomes and halflings. No broadly effective treatment of hypertension has been discovered for dwarves. The majority of human, elven, and half-elven users choose to use tangsin for the pleasant taste and mild feelings of euphoric connection it engenders.
