Thepoorermentalfunctionseenamongalcoholics，manyofwhomalsoregularlysmokecigarettes，maybepartlyduetothelongtermeffectsofnicotine(尼古丁)，newresearchsuggests.

Thisfindingmayseemcounterintuitive(违反直觉的)，sincemanysmokersshowthattheyfeelquickerandfocusedaftersmoking.Indeed，researchshowsthatimprovedmentalfunctioningisoneoftheimmediateeffectsofnicotineexposure.Chronic(慢性的)smoking，however，isknowntohavetheoppositeeffect.Studiesshowthatupto87percentofalcoholicssmokecigarettes.

Yet，fewstudieshavelookedintocigarettesmokingasafactorthatmightexplainthecognitive(认知的)lackreportedamongalcoholics.Tosearchforthatassociation，Glassandhercolleaguesexaminedbrainfunctionamong172menfromthesamearea，including103menwhoabusedalcohol.Theteamfoundthatmenwithhigherscoresonthelifetimealcoholproblemsscale(LAPS)andthosewhoreportedahighernumberofpackyearsofsmokingbothhadlowerIQscores.
