Addiction from group gambling, can be contagious from one friend to another. So, if a gambler continues playing the game with the addicted person, it could affect the next person. The need to caution the player to stop gambling is also important. Because as a friend, he's meant to be helped. However, he shouldn't be neglected. But moderated. Letting him stay on his own without an attention, will increase his compulsive gambling. And he can establish friendship with different gamblers who are not yet aware of his addiction. A friend should check those possibilities before avoiding another addicted gambler. If the still responsible gambler is capable of mingling with his addicted friend without engaging into gambling with him, which is almost impossible, he should be there for him. Especially when the person doesn't have close family that'll take care of him.
