That's a valid point. When comparing the addiction of gambling with drugs the latter has more weight due to the physical side effects of drugs on the body.
If our health is good we can still make money but if our health is not supporting us then it is very difficult to make money.
As they say, health is wealth. But ofcourse both the addictions are bad since they can both lead to death.
At some point we can't compare this two because they are in different scenario but there's almost the same thing about it as well. People change their life when they are addicted to something, it can also cause other people to lose their love ones because of their behavior. It will also reflect to your physical appearance, those who fall into addiction give less attention to their body and hygiene.
