I always have a mindset that gambling is fun and entertaining, I used to played for profit but now I played for entertained myself, I like to share my point of view about gambling, but I afraid when I introduce gambling to someone who cant control himself or herself then it can become a problem, and I can become the one that make him/her become addicted

So in one my hand I'd like people to enjoy gambling but in one hand I afraid it can turned into disaster and I could the person that cause the person become addicted, so I kind of confused when someone come and asked me to teach or explained thing about gambling, should I teach them or I just ignore them? How can I teach or convince them that gambling is only for fun? Is it a wrong idea to teach or convince them to gamble for fun?
