Why do smokers put the first cigarette backwards? What's the point?

Generally speaking, it is hard box cigarettes that have this saying.

Buy a pack of cigarettes, open it, choose one first and put it backwards. You have to smoke this last, and you can't give it to others, or you will be unlucky. It is usually called a wishing cigarette, but few people wish on it. But in the end everyone smoked. Some people don't smoke, but leave one in each box.

A pack of cigarettes, 20 in the first row, seven; Middle row, six branches; Last row, seven cigarettes. Take out the middle one in the first row, make a wish, and put it upside down. This kind of cigarette is called wishing cigarette ... but only when you smoke it last will your wish come true.

A little superstitious.
