I totally agree with this statement. I have a problem with cigarette smoke, some of the cigarette smoke mearly causes me to have a tight sensation in my throat, others (maybe a different brand) causes my whole chest to become tight and I have to leave the area ( or smoke smelling person) immediately. The most important thing to consider is the safety of your patients. I am a very healthy individual with no other breathing problems, until exposed to certain brands of cigarette smoke. I don't know which ones effect me until someone exercises the right to smoke, and just happens to reek of the one that wrecks up my breathing. I also agree that to a non- smoker or allergic person the smell does NOT go away because Febreaze, or some other spray is used to try and mask it. It only compounds the problem by adding more chemicals to the carcinogenics and causing in some cases an even stronger odor for the patient to react to. To the original poster I am very sorry that your instructor chose to treat you in a childish manner. But I hope that you can continue without any more problems from this. Good luck, Gichasome
