Answer:
Even though smoking rates have long been on the decline, nicotine addiction still affects 20% of the US population today. Moreover, nicotine dependence shows high comorbidity with many mental illnesses including, but are not limited to, attention deficit hyperactivity disorder, anxiety disorders, and depression.
Mental disorders should be viewed like any other physical illness because if we just treat mental disorders like they're nothing, then they are just going to get worse and worse. It's very important to realize what people are going through and treat it with caution and take it seriously.
If we treated mental illness like they way we treat cancer and deceases, then maybe we would make so much more progress than we are currently. This is not a joke and mental illness isn't something that goes away over night, so please view it in a different/precise way and help make an impact on it!
I hope this helped! Have a nice day!
