The smoking habits of 119 subjects without silver/mercury dental fillings were compared to 115 subjects with amalgams. The amalgam group had 2.5-times more smokers per group than the non-amalgam group, which was highly significant. Because mercury decreases dopamine, serotonin, norepinephrine, and acetylcholine in the brain, and nicotine has just the opposite effect on these neurotransmitters, this may help explain why persons with dental amalgams smoke more than persons without amalgams.
将119名没有银汞合金补牙材料的受试者的吸烟习惯与115名有汞合金补牙材料的受试者进行了比较。汞合金组每组的吸烟者数量是非汞合金组的2.5倍，这一差异具有高度显著性。由于汞会降低大脑中的多巴胺、血清素、去甲肾上腺素和乙酰胆碱，而尼古丁对这些神经递质的作用则相反，这可能有助于解释为什么有牙科汞合金补牙材料的人比没有补牙材料的人吸烟更多。
