GET OUT NOW!
RRRruuuuuuuuuuuuuuuuuuuuuuuuuunnnnnnnnnnnnnn!!!!!! Save the puppies!!!!!!!!!!!!!!!!!!!!!! xD
Yeah, but only if they don't slow you down. You're in survival mode, now.
All I have to do is think about oranges or Korean food, or mexican food, and I can smell it. My imagination is vibrant.
Are there any smoke-stacks close to where you live, or maybe a freeway where semi-trucks might be driving? Maybe you have early signs of MS or stroke... it is most commonly associated with some form of brain damage if the symptom isn't external. Do you use drugs? ^_^
Is this every single day or do you smell this smoke randomly? It could be coming from the Air Force base. I live fairly close to an AFB and sometimes I can smell sulfur when I drive by that base. Is it Winter where you're from? It could be merely that one of your neighbors is burning some rotten wood, diapers, or something else that really should be in their fireplace. Sometimes if they burn something slowly you wouldn't notice any smoke coming from their chimney. If it has only began recently and it is Winter in your area then I'd have to say that this would be the simplest answer. ...and usually, the simplest answer is correct! xD
Hmm... If this has only occured recent then I suspect it may be seasonal. If you're experiencing headaches or fatigue/nausia with this smell then it might be something more serious. Also, are you sure that no one in your household is using drugs around you? Or, possibly, your neighbors have recently opened up a meth-production house in their basement. When someone cooks meth the smell tends to travel.
Plenty of things can cause this... lead, mercury, or arsenic exposure can make you smell smoke for example
Hm, I'm not sure. You might want to see an ENT, or neurologist to rule things out.
