You will agree with me that society and the environment can have a great influence on the lifestyle of every individual, you often can find yourself doing, or being involved in that activity that almost everyone is involved with in that your locale as a result of influence. Now considering someone who is a gambling addict, is there any possibility of him/her becoming better if they are relocated to another environment or society where people around are not involved in gambling?
To answer your question,
1.If someone have the decision of changing location due to his addiction to gambling and use this as a means of helping his/her out of this situation, Then "Yes" but must have to engage self with other activities in that locale, hence you might be tempted to finding means to continuing your gambling in that new environment, Except if that environment doesn't have network /internet and no betting shops around.
Can someone still develop the habit of gambling and become an addict even though no one around gambles?
2. Though base on research that addition to gambling could be linked to traits /heredity, However something must spark it up as someone begins to grow or start getting mature which could be Persistent of exposure to gambling friends or environment.
can make someone gradually develop gambling habit. In the absence of this factors, Then "No" is the answer.
