Hmm this is actually a difficult question on to which is worse since both have detrimental effects. Maybe we should try to decide based on the timeline?

Short-term: Gambling
Long-term Smoking Cigar

The problem with gambling is that you quickly realize its effects and impacts to your life once you succumb to addiction. You tend to sacrifice your time and resources to bet instead of doing something recreational or helpful. This quickly cascades into a bigger issue if you have a family to support and obligations to meet every week.

With cigar addiction, you will only realize its harmful effects to your body at a certain time and age. People do not quickly get cancer by just smoking a few sticks of cigar but it is a collective action and continuous use that will eventually lead to that.
