You have misinterpreted some things Loneline does not make anyone drug addict. Loanlines can be an attraction for a gambler because when he gambles and loses and does not have enough money to re-deposit, he will try to borrow from others to recover his losses. So Lonelines can make a gambler more addicted to gambling. In this case, if he wins the gamble and recovers his losses, he can repay his loans, but if he loses and loses them too, he is in great danger. And this is why you should never gamble with a loan
Loneliness can make someone more susceptible to behaviors that we may think to be too risky, as if they had a friend to their side watching what they were doing they could tell them that what they are doing is wrong, but without that support it will be easier for someone to develop some issues, still this only increases the chances of this happening a little bit since such a state cannot really last for long, especially now that we live in a society in which you can contact with people from all over the world and drive away those feelings.
