In the Peruvian Amazon, tobacco is considered to be a medicine. They use a stronger type of tobacco called "mapacho" which is pure, no additives. A regular brand cigarette contain about 10% additives (mainly sugars but also a lot of chemicals no one has ever heard of).

And since mapacho is so strong you can get the effects without even inhaling the smoke, which is healthier for the lungs.

Mapachos are used to clean out bad energies and keep bad spirits away.
