What is the healthiest tobacco to buy?

I'm curious to know, what criteria are typically used to determine the healthiest tobacco product to purchase? Is it solely based on the amount of nicotine or tar content, or are there other factors that come into play? Additionally, are there any specific brands or types of tobacco that are generally considered healthier than others, and if so, what sets them apart? I understand the inherent risks associated with tobacco use, but I'm interested in learning more about the relative health benefits of different options.
