Excessive gambling can distract youth from their studies or work, leading to poor academic performance it is proven and tested based on what we have experienced with my family member. It also arises some conflicts regarding to their emotions because if they are already addicted, the people around them can be affected too because they will be more aggressive , frustrated and agitated.
I think this is one disadvantage of gambling that is ignored at times by most people, distraction, it can come in different forms and aswell affect different aspects of their live consciously or unconsciously, but the sad part is since they are you they may not want to agree to the fact that it is gradually becoming a source of distraction as they may feel they still gat everything under control.
It's very much advisable for youths who know they have cases of struggles with addiction and also issues of been able to control themselves when it comes to stopping a particular habit which they just got indulge in recently, youths especially those who just got into adulthood should most possibly avoid gambling because at that stage they may not be able to control it enough not to graduate to addiction.
Adults who find youths indulging in such habits and know them may not be able to keep it under control should as much as possible advise the youths to try and stop at the early stage where they are yet to comitt so much to it which may later make it difficult to leave. Although some youths may have the ability to get control of themselves, such may be allowed.
