Validation of a LC-MS/MS method for quantifying urinary nicotine, six nicotine metabolites and the minor tobacco alkaloids--anatabine and anabasine--in smokers' urine. [PDF]
PLoS ONE, 2014 Tobacco use is a major contributor to premature morbidity and mortality. The measurement of nicotine and its metabolites in urine is a valuable tool for evaluating nicotine exposure and for nicotine metabolic profiling--i.e., metabolite ratios.

Does e-cigarette nicotine strength influence substitution for combustible cigarettes? [PDF]
J Exp Anal BehavAbstract Using the Experimental Tobacco Marketplace, we examined the effects of e‐liquid freebase nicotine strength (3–24 mg/mL) and e‐liquid price (US$0.25–$1.00/mL) on behavioral economic substitution for cigarettes in dual cigarette/e‐cigarette (n = 41) and exclusive cigarette (n = 40) users.
