Talk:Headache attributed to a substance or its withdrawal

Common
"Common hazards in our environment also cause toxic headaches with exposure. These include chemicals, fumes, pollution, allergens and other health hazards. These toxins can be found in our communities, workplaces, and homes." Not really sure about this-- sounds like a pretty broad claim, and it isn't cited.
