“…Other remarkable compound found was the 1,3-butadiene which presents the highest cancer risk index of all constituents of cigarettes smoke [2] and which metabolite 1,2:3,4-diepoxybutane was shown to induce SCE in vitro in human lymphocytes [27].…”

“…Tobacco is a natural product that consists of more than 3800 constituents (4800 compounds in tobacco smoke) ranging from small molecules such as hydrocarbons, terpenes, carbonilics, phenols, or nitriles, to macromolecules as cellulose, lignin or nucleic acids. These compounds suffer transformations due to the high temperatures achieved during the tobacco consumption and some of them are toxics and carcinogenics [2]. Among these compounds more than 50 are known carcinogens, such as polycyclic aromatic hydrocarbon (PAHs), N-nitrosamines, aromatic amines, and trace metals [3].…”

“…For example, some studies have reported benzo[a]pyrene (B[a]P) at greater levels in cannabis smoke than tobacco smoke [22], whilst others report cannabis smoke to have less B[a]P [27]. A reason for disagreement between the studies of cannabis smoke may be the source or variety of the cannabis being tested, just as different tobacco products show different smoke properties [36]. Cannabis smoke studies have provided substantial information on the constituents of cannabis smoke, however it is difficult to draw any conclusions regarding the variability from different sources of cannabis.…”

“…We used a response factor from an external nicotine standard curve, run at concentrations of 3.1, 12.5 and 25.0 mg/mL (R 2 0.98), to estimate the concentration of compounds, other than D 9 THC, identified in the smoke extracts [36]. Interpretation of results for compounds other than nicotine and D 9 THC should therefore be considered semi-quantitative and for comparative purposes between the samples of cannabis.…”

Studies have compared the chemical properties of tobacco smoke to those of cannabis smoke, with the objective of identifying the chemical attributes responsible for the mutagenicity and carcinogenicity of cannabis smoke. Comparative studies have included small sample sizes and produced conflicting results. The aim of this study was to assess the major chemical and physical variations of cannabis smoke across a range of cannabis samples of different potencies and origins, sourced from the illegal market in New Zealand. Twelve cannabis samples were studied ranging from 1.0% to 13.4% delta-9-tetrahydrocannabinol (D 9 THC) content. A smoking machine was used to smoke "joints" (cannabis cigarettes) and the chemical/physical properties of the smoke assessed. The chemical constituents of the smoke extracts were analysed by gas chromatography/mass spectrometry. A range of different chemical constituents (in addition to D 9 THC) were identified and their concentrations estimated. Terpenoids were identified as the major variable in cannabis smoke, showing a 40-fold range in total terpenoid content. Analysis of the total particulate matter showed that significantly different levels of particulate matter were produced between the different cannabis samples, ranging from 14.6 to 66.3 mg/g of cannabis smoked. The D 9 THC delivery efficiency during smoking was also investigated and produced consistent results showing a mean and median of 12.6% and 10.8%, respectively, of the theoretically available D 9 THC (ranging from 7.2% to 28.0%).

Abstract:The effect of three synthesised mesoporous catalysts (a SBA-15 and two MCM-41) on the smoke of two reference tobaccos (1R5F and 3R4F) has been studied. Mixtures of the catalysts and each tobacco were smoked under the ISO 3388 standard conditions. The gaseous compounds and the particulate matter condensed in the filter tip (TPM-F) and in a trap located downstream (TPM-T) from the mainstream smoke were analysed separately. The results obtained show that these catalysts directly mixed with tobacco are capable of reducing the yield of most of the compounds studied in the mainstream tobacco smoke. SBA-15 is a better additive for reducing the amount of the compounds analysed in 1R5F and 3R4F tobaccos, both in the liquid fraction (TPM-F and TPM-T) and in the gas fraction. The effect of the studied catalysts is higher on the full-flavour cigarette than on the ultra-low one. As an example, the reductions observed for CO and nicotine in TPM-T from 3R4F as a consequence of the SBA-15 addition were 46% and 77%, respectively. Thus, although the three checked materials are able to provide noticeable reductions, the best is the one having the higher size of pores (SBA-15).
