The credit card industry works similar to the cigarette industry. what reasons caused culture to change its view of cigarettes o
tankabanditka [31]

The credit card industry and cigarette industry are very similar in terms of negative influence on personal finances.

<h3>What is credit card?</h3>

A credit card is a sort of payment card that uses a line of credit rather than the account holder's cash deposits to make purchases.

Tobacco use can have a negative impact on personal finances due to the sheer high price of tobacco products, wasted pay owing to sickness absence, plus hospitalization rates due to the higher risk of illness associated with smoking use.

If you let that debt grow, you may find that the amount of interest you owe equals or even exceeds your original principal, forcing you to spend a lot just to pay it off.

Thus, the credit card industry and cigarette industry are very similar in terms of negative influence on personal finances.
