Twelve female smokers smoked two of each of three types of cigarettes in three sessions. One cigarette was smoked with and the other one without nose blocking. Total puff volumes increased for ultralow tar/nicotine (tn) cigarettes as compared with habitual regular tar/nicotine (TN) cigarettes and regular tar/ultralow nicotine (Tn) cigarettes, as the result of an increase in the number of puffs. TN and tn, but not Tn cigarettes changed heart rate and beta-power in the electroencephalogram; all three reduced craving, although they differed considerably in subjective acceptance. Blocking of olfactory cues influenced respiration and reduced the average puff volumes, taste, and enjoyment, but it did not differentially affect any parameters among the TN, tn, and Tn cigarettes, which suggests that olfaction plays a minor role in regulating puffing behavior. It was concluded that as compared with regular TN cigarettes, only the tn, but not the Tn cigarettes were oversmoked by about 35%, and that Tn cigarettes might be useful for assessing nonnicotinic factors in cigarette smoking.

UI	MeSH Term	Description	Entries
D009538	Nicotine	Nicotine is highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission. Nicotine is also important medically because of its presence in tobacco smoke.	Nicotine Bitartrate,Nicotine Tartrate
D009666	Nose	A part of the upper respiratory tract. It contains the organ of SMELL. The term includes the external nose, the nasal cavity, and the PARANASAL SINUSES.	External Nose,External Noses,Nose, External,Noses,Noses, External
D003463	Cues	Signals for an action; that specific portion of a perceptual field or pattern of stimuli to which a subject has learned to respond.	Cue
D004569	Electroencephalography	Recording of electric currents developed in the brain by means of electrodes applied to the scalp, to the surface of the brain, or placed within the substance of the brain.	EEG,Electroencephalogram,Electroencephalograms
