The New Worlds “Brown Gold”.

2. Where it Started. The practice began as early as 5000–3000 BC.

Tobacco was dubbed “Brown Gold”.

3. What is Smoking?
Smoking is the most common method of consuming tobacco, and tobacco is the most common substance smoked.
The agricultural product is often mixed with other additives. The resulting vapors are then inhaled and the active substances absorbed through the alveoli in the lungs.
