Hello, Visitor 1,
I am not sure what it is that you are posting, but it seems that you may be concerned about a baby living in your apartment building that is possibly being exposed to second-hand smoke. You also mention that smoke is coming into your apartment as well.
Reference the infant, you can call the Child Protective Services (CPS) hotline, 24-hours-a-day, 7-days-a-week; the number is 1-800-800-5556.
Reference the smoking in the hallway and the smoke coming into your apartment, you should contact the apartment complex manager. I would be surprised if there was not a rule regulating smoking inside the building hallways.
And, last but not least, you can call the Fort Wayne Police Drug Tip hotline at 427-1262 reference the illegal drug use.
