As with any gambling activity, there are some risks associated with smoking and blackjack. In particular, smokers tend to have a higher rate of losing at blackjack than nonsmokers, and the smoke from cigarettes can make it harder to read cards.
Despite these risks, some people continue to smoke while playing blackjack. One study found that about one-third of all smokers who gamble regularly smoke while playing blackjack.
It is important to keep in mind that there is no guarantee that smoking will help you win at blackjack, and it could actually increase your chances of losing money.
Ultimately, whether or not you should smoke while playing blackjack depends on your own personal risk tolerance and gambling style. If you are a smoker and want to give blackjack a try, be sure to take the proper precautions to minimize your risks.
