I think that all people have dependence. Someone is addicted to thrill and engaged in extreme sports. Someone is dependent on computer games ... there are people who are addicted to other people. But smoking and alcohol can be called the most ancient dependencies.
They are imposed on us by the society in which we live, are imposed in advertising. In films, successful people often consume alcohol or smoke a cigarette. Adolescents are more likely to advertise, but an adult is no exception.
A photo with meaning and I see it as you described. The external world is in the background, it is as if in a fog. Attention is focused on the ashtray, it is a symbol of human dependence. People concentrate on their addictions and do not notice the world around them. Unfortunately, that's the truth.
But we should not be like people who behave this way. We ourselves are responsible for what we do. So if you want to change the world, start with yourself - show a positive example to others.
Thank you and good night :)
