An increasingly popular method of consuming marijuana is through the smoking of "blunts," cigar products in which some or all of the tobacco filler is removed and repacked with marijuana. Even if all tobacco filler is removed from the cigar product in the process of making blunts, nicotine may be present in the wrapper of the cigar product. This preliminary analysis quantified the nicotine content in wrappers of cigar products commonly used for blunt smoking.
Five cigar products (3 large cigars, 2 cigarillos) were tested, yielding physical characteristics of cigar length, diameter, weight, and wrapper weight. Nicotine concentration in the wrapper of each cigar product was analyzed via gas chromatography/mass spectrometry. Total nicotine content in the wrapper of each cigar product was computed as the product of cigar wrapper weight and nicotine concentration in wrapper.
Depending on the product, the cigar wrapper contributed between 8 and 18% of the weight of the entire cigar article. Total nicotine content in the cigar wrapper ranged from 1.2 to 6.0mg per cigar.
All 5 tested cigar products had wrappers that contain quantifiable levels of nicotine, indicating that users of blunts may expose themselves to some degree of nicotine, the addictive component of tobacco. Future experimental studies that examine the efficiency of nicotine delivery from typical blunt smoking, as well as surveillance studies that quantify the number of blunts smoked by an individual per day, are needed to evaluate the contribution of blunt smoking to nicotine dependence.
一种越来越流行的吸食大麻的方式是吸食“钝器”，即雪茄产品，其中部分或全部烟草填充物被取出，再用大麻重新填充。即使在制作钝器的过程中从雪茄产品中去除了所有烟草填充物，雪茄产品的包装纸中仍可能含有尼古丁。本初步分析对通常用于吸食钝器的雪茄产品包装纸中的尼古丁含量进行了量化。
测试了五种雪茄产品（3支大雪茄、2支小雪茄），得出雪茄长度、直径、重量和包装纸重量等物理特征。通过气相色谱/质谱法分析每种雪茄产品包装纸中的尼古丁浓度。每种雪茄产品包装纸中的总尼古丁含量通过雪茄包装纸重量与包装纸中尼古丁浓度的乘积计算得出。
根据产品不同，雪茄包装纸占整个雪茄制品重量的8%至18%。每支雪茄包装纸中的总尼古丁含量在1.2至6.0毫克之间。
所有5种测试的雪茄产品的包装纸都含有可量化水平的尼古丁，这表明吸食钝器的使用者可能会在一定程度上接触到尼古丁，即烟草中的成瘾成分。需要进一步的实验研究来检验典型的吸食钝器方式中尼古丁的递送效率，以及量化个人每天吸食钝器数量的监测研究，以评估吸食钝器对尼古丁依赖的影响。
