Don't bring your issues with the neighbors smoking in their apartment that they pay for to the neighbors. They are doing what they want to in their apartment and they ahve every right to do it.
Get some purifiers and see if that helps while you look for a new place to live.
Here are some tips on how to naturally help prevent an asthmatic episode:
•Decrease protein to 10 percent of daily caloric intake. Replace animal protein as much as possible with plant protein
•Eliminate milk and milk products, substituting other calcium sources.
•Eat organically grown fruits and vegetables as much as possible.
•Eliminate polyunsaturated vegetable oils, margarine, vegetable shortening, all partially hydrogenated oils that might contain trans-fatty acids, all foods that might contain trans-fatty acids (such as deep-fried foods).
•Use extra-virgin olive oil as your main fat.
•Increase intake of omega-3 fatty acids.
•Always drink plenty of water to keep your respiratory tract secretions more fluid.
•Experiment with eliminating (one at a time) wheat, corn, soy and sugar for six to eight weeks to see if the condition improves.
•Eat ginger and turmeric regularly for their anti-inflammatory effects.
•Have some manipulative work done on the chest to break up restrictive patterns in nerves and muscles that develop in chronic asthma. The best systems I know for this are osteopathic manipulation, especially from a practitioner of cranial therapy, and Rolfing, a form of deep-tissue massage.
•Minimize contact with respiratory irritants, such as smoke, dust, molds, and volatile chemicals. Remove sources of offending materials from your home, install a good air filtration system, or consider moving if the air is generally bad where you live. Experiment with living in other locations: in high mountains, the desert, or near the seacoast. Asthma may improve greatly with a change of climate.
•In adults, GERD (acid reflux disease) may be an underlying cause of asthma. In such cases, successful treatment of the digestive problem will often clear up the asthma.
•Experiment with traditional Chinese medicine and Ayurvedic medicine (the traditional healing system of India). These systems are sometimes able to offer significant help through more specific dietary adjustments and herbal treatments.
I hope this helps.
