Oh I believe there are a lot of people who are getting addicted in lottery, just in a different way than the casino addiction.
I think I know the reason.
In our country, it is because of the people being persistent.
I don't know their basis but all I know is that they want to bet their numbers, maybe it is a number symbolizing the birthday of their child, partner maybe sibling, and they keep that for days. Miraculously, some won consolations like winning 2 numbers out of 3 and some won the main prize. That is the reason, I think they are addicted.
