Pipeweed

Potent form of tobacco specially grown by the Halflings of Grenshire, and exported all over western Corwyn. The weed is not poisonous, but can become addictive if large enough quantities are used over an extended period of time. For some obscure reason the Halflings are not affected by this side effect as are humans, dwarves, and elves. The secrets of planting, growing, and harvesting these rare weeds are kept in the strictest secrecy by the Halflings of Grenshire.
