1492-10-12: On this bright morning Columbus and his men set foot on the New World for the first time, landing on the beach of San Salvador Island or Samana Cay in the Bahamas, or Gran Turk Island. The indigenous Arawaks, possibly thinking
the strange visitors divine, offer gifts. Columbus wrote in his journal, “the natives brought fruit, wooden spears, and certain dried leaves which gave off a distinct fragrance.” As each item seemed much-prized by the natives; Columbus accepted the gifts and ordered them brought back to the ship.
The fruit was eaten; the pungent "dried leaves" were thrown away.”

1492-11: Rodrigo de Jerez and Luis de Torres, in Cuba searching for the Khan of Cathay (China), are credited with first observing smoking. They reported that the natives wrapped dried tobacco leaves in palm or maize "in the manner of a musket formed of paper." After lighting one end, they commenced "drinking" the smoke through the other.

Jerez Becomes First European
Smoker
Jerez became a confirmed smoker, and is thought to be the first outside of the Americas. He brought the habit back to his hometown, but the smoke billowing from his mouth and nose so frightened his neighbors he was imprisoned by the holy inquisitors for 7 years. By the time he was released, smoking was a Spanish craze.
