Does anyone actually smoke swishers

The amount of nicotine in each cigarette was from 6. Standard textbooks, databases, and safety sheets consistently state that the lethal dose for adults is 60 mg or less 30—60 mg , leading to safety warnings that ingestion of five cigarettes or 10 ml of a dilute nicotine-containing solution could kill an adult. Although the Puff Bar website states it has now ceased all online sales and distribution in the U.

Cardiac Surgeon Lucian Durham warns inhaling a single puff from a vape could make you his next patient at Froedtert and Medical College of Wisconsin. The lung damage he has seen in patients is the equivalent to someone smoking cigarettes for decades. Currently there is no legal way to recycle them in the U. E-cigarettes, including rechargeable batteries and the cartridges and bottles that contain e-liquids liquid nicotine mixtures , can pose a threat to human health and to the environment if they are not disposed of properly.

E-cigarette and e-liquid waste should not be thrown in the regular trash or flushed down a sink. Remove the cartridge or pod from the battery. It is illegal to place rechargeable batteries in the trash. Although they appear rare, these explosions are dangerous.

However, the legislation on little cigars remains unclear and flavored little cigars are currently available for purchase. Since inhaled tobacco smoke directly exerts toxic effects on the lungs, we tested whether non-flavored and flavored little cigar smoke exposure had the potential for harm in cultured pulmonary epithelia.

We cultured Calu-3 lung epithelia on both well plates and at the air—liquid interface and exposed them to smoke from non-flavored Swisher Sweets and flavored sweet cherry, grape, menthol, peach and strawberry Swisher Sweets little cigars.

Chronic exposure to smoke from all types of little cigars induced the activation of the two major apoptosis pathways, namely the intrinsic mitochondrial-mediated and the extrinsic death receptor-mediated pathways. Both flavored and non-flavored little cigar smoke caused similar levels of toxicity and activation of apoptosis, suggesting that flavored and non-flavored little cigars are equally harmful. Hence, the manufacture, advertisement, sale and use of both non-flavored and flavored little cigars should be strictly controlled.

Tobacco smoking and second-hand smoke exposure are major causes of mortality and morbidity worldwide. Hence, little cigar distribution and sales are now controlled, with warning statements being required on packaging.

Although only menthol flavoring is allowed in cigarettes, diverse flavors are currently permitted in little cigars.

Although several studies have investigated the effects of individual flavors on biological systems, 15 — 20 the effect of flavored tobacco smoke on human airway epithelia has not been determined. Our present study was designed to evaluate the relative toxicity induced by flavors by exposing cultured airway epithelial cells to regular versus flavored little cigar smoke.

We also evaluated the autophagic response of epithelial cells to non-flavored and flavored little cigar smoke exposure. Furthermore, changes in different apoptotic proteins after chronic exposure of non-flavored and flavored little cigar smoke were evaluated using an apoptosis protein array system. To evaluate the relative effects of non-flavored versus flavored little cigars, we exposed Calu-3 cells cultured on well plates to little cigar smoke with air exposure serving as the control.

Acute exposure to little cigar smoke that is, 10 puffs significantly decreased the percentage of live cells and significantly increased the percentage of dead cells, irrespective of flavoring Figures 1a and b.

Although there was no significant difference between most flavors and the non-flavored brand, peach flavor caused a significantly greater decrease in the percentage of live cells compared with non-flavored smoke. Four out of five flavors tested grape, menthol, peach and strawberry also significantly increased cell death compared with the non-flavored little cigar group Figures 1a and b.

Acute little cigar smoke exposure causes Calu-3 cell death. Relocation of phosphatidylserine from the inner side of the plasma membrane to the cell surface is an early event of apoptosis that can be detected by the binding of Annexin-V to phosphatidylserine to identify proapoptotic cells. The proapoptotic and inviable cells were significantly increased in non-flavored and flavored little cigar smoke-exposed cells compared with the air exposure as indicated by increased Annexin-V and DAPI binding Figures 2a and b.

Four out of five flavors sweet cherry, grape, menthol and peach significantly increased Annexin-V fluorescence indicating increased numbers of proapoptotic cells compared with non-flavored little cigar smoke Figure 2a. No significant difference in DAPI uptake was observed between non-flavored and flavored little cigar smoke groups Figure 2b. Acute little cigar smoke exposure induces apoptosis and autophagosome formation. However, for two out of five flavors that is, grape and menthol while the increase was less than for non-flavored tobacco exposure, it was still significantly greater than the air control Figure 2c.

These observations indicate that despite the inclusion of flavors to mask any harsh taste, cytotoxicity remains unaltered. Intracellular calcium acts as an important second messenger that regulates cellular signaling including changes in gene expression and the transition to apoptosis.

However, no significant difference was observed between non-flavored and flavored little cigar smoke exposure Figure 3. Acute little cigar exposure increases cytosolic calcium levels. Intracellular calcium increases were calculated as a ratio of final to initial fluorescence after background subtraction. Compared with air-exposed cultures, little cigar smoke exposure, irrespective of flavors, significantly increased LDH release into the basolateral media Figure 4a.

The degree of LDH release was unrelated to flavor and was significantly increased in all the smoke exposure groups Figure 4a.

Chronic little cigar smoke exposure induces toxicity and activates autophagy in polarized Calu-3 cultures. Autophagy is associated with programmed cell death and has been implicated in disease pathogenesis.

We chronically exposed polarized Calu-3 cultures to 10 puffs of whole tobacco smoke per day for four days and measured LC3B-II protein levels. LC3B-II was significantly elevated in all of the chronic smoke-exposed groups irrespective of flavor used Figures 4b and c.

However, no significant difference was observed between flavored and non-flavored little cigar smoke exposures Figures 4b and c. Apoptotic cell death plays a crucial role in pulmonary disease progression. Out of the 35 proteins tested, we identified the presence of 30 proteins Figure 5a.

Eighteen proteins were altered in chronic smoke-exposed cells. That is, 2 proteins were downregulated and 16 proteins were upregulated after little cigar smoke exposure compared with air Figure 5a and Table 1. Chronic smoke exposure caused a decrease in the antiapoptotic protein Bcl-2 irrespective of the little cigar flavor Figure 5a and Table 1.

Coupled to this, the proapoptotic mitochondrial protein Bad, which is responsible for mitochondrial membrane pore formation and cytochrome c release, was elevated across all groups Figure 5a and Table 1 , indicating that the intrinsic pathway of apoptosis was activated following chronic smoke exposure. Release of cytochrome c from mitochondrial membranes into the cytosol leads to the activation of caspases, enabling the execution of apoptosis.

Chronic little cigar exposure induces changes in multiple apoptotic proteins. Polarized Calu-3 cells were chronically exposed to flavored and non-flavored little cigar smoke for 4 days and protein lysate was taken for apoptosis protein array analysis. Each value is the mean of four dot blots from two separate runs using lysate pooled from three cultures smoked in two separate experiments. Each node represents one differentially expressed or phosphorylated apoptotic protein.

Line thickness between nodes represents extent of protein interaction. Stabilization of p53 by phosphorylation P-p53 has a pivotal role in the progression towards apoptosis in the event of stresses such as DNA damage. Three out of five flavors grape, menthol and peach significantly increased S46 phosphorylation compared with non-flavored smoke, with grape flavor showing increased S phosphorylation compared with non-flavored smoke Table 1.

Our observations indicate that stress caused by chronic exposure of smoke resulted in stabilization of p53, which subsequently may regulate cell growth and alter transcriptional activation of stress-related genes.

Chronic exposure to little cigar smoke regardless of flavor increased phosphorylation of Rad17 at Ser Figure 5a and Table 1 , which is required for genotoxic stress response. IAP bind to caspases to hinder the progression of cell death.

However, cIAP-2 was found to be downregulated in all groups compared with air Figure 5a and Table 1 , suggesting that the cellular ability to attenuate apoptosis was diminished. For menthol and strawberry flavors, the decrease was significantly greater compared with non-flavored smoke Table 1. HSPs are constitutively expressed and act as molecular chaperones to modulate apoptosis in both positive and negative ways.

Previous studies have demonstrated the association of HSPs with tobacco smoke-induced toxicity. Furthermore, peach flavor significantly increased HSP27 levels compared with non-flavored smoke Figure 5a and Table 1. We further evaluated the levels of procaspase-3 and cleaved caspase-3 in chronic smoke-exposed culture lysates to evaluate the extent of activation of apoptosis following smoke exposure. Both flavored and non-flavored little cigar smoke exposure increased pro- and cleaved caspase-3 levels, signifying apoptosis Figure 5a and Table 1.

Using the list of significantly altered and phosphorylated apoptotic proteins in chronic smoke-exposed cultures, we constructed protein—protein interaction networks using the STRING v. The network shows that execution of apoptosis by caspase-3 in chronic smoke-exposed cultures is driven by both the intrinsic and the extrinsic pathways Figure 5b.

The intrinsic pathway was activated following decreased antiapoptotic Bcl-2 protein with increased proapoptotic Bad, leading to cytochrome c release. Other associated proteins influenced the apoptosis execution indirectly and the interactions between caspase-3 and HSPs were not as strong as those seen with the Bcl-2 family proteins and death receptors Figure 5b.

In spite of the fact that in the United States of America the Master Settlement Agreement prohibits tobacco companies from targeting youths, 43 tobacco manufacturers continue to use flavors like fruit, candy, liquor and coffee to recruit new smokers. Although individual flavor constituents like anethole, eugenol, pulegone, estragole, piperonal, coumarin and myristicin exert toxic effects on biological systems in high doses, 15 — 20 the biological activity of tobacco smoke is unaltered by these ingredients.

Our current study provides evidence that flavored little cigar smoke causes similar cytotoxicity to pulmonary epithelia as non-flavored little cigar smoke. For example, acute exposure to 10 puffs of little cigar smoke, altered live-dead cell staining, proapoptotic and apoptotic cell staining and autophagosome formation, irrespective of flavor Figures 1 and 2.

We also observed that some flavors were potentially more harmful than others. For example, the menthol, peach and strawberry flavors significantly increased cell death compared with non-flavored little cigars following acute smoke exposure Figure 1b.

Similarly, acute exposure to sweet cherry, menthol and peach flavors significantly increased the formation of proapoptotic cells compared with non-flavored little cigars Figure 2a. The ability of tobacco smoke exposure to elicit an autophagic response was also evaluated, and we observed that autophagosome formation was enhanced for all flavors Figure 2c.

However chronically exposed air—liquid interface cultures showed uniformly increased LC3B-II protein levels, indicating an increase in autophagy Figures 4b and c. As all tested flavors induced apoptosis, we then used protein array analysis to evaluate additional apoptotic proteins. We identified similar responses following exposure to smoke from both non-flavored and flavored little cigars, suggesting that all of the little cigars with or without flavor caused activation of both intrinsic and extrinsic pathways of apoptosis Figures 5a and b.

Cigarette smoke-exposed airway epithelia in vitro give similar responses as seen in vivo , including inhibition of the CFTR anion channel, increased mucin secretion and induction of apoptosis. Based on our observations, we conclude that little cigars are highly cytotoxic and can induce cell damage and apoptosis. Furthermore, the addition of flavor leaves the cytotoxic effects of the little cigars unaltered, suggesting that they are equally as harmful, despite the mitigating taste effects.

In conclusion, considering the appealing effects of these products to new smokers and their potential for toxicity, we propose that flavored little cigars should be regulated in a similar manner as flavored cigarettes. Position the cigar above the flame to prime the cigar. At this point, the cigar is ready to smoke. You probably already know as much, but you do not inhale a cigar. The key here is a good puff, akin to that delicate and pretend first hit of weed you took as a teenager or pulling air through a straw without actually inhaling.

Think of the smoke as something you mull over and even chew on more than ingest. Take in enough to fill your mouth and then blow it out.

Repeat four or five times maybe more until your cigar starts producing thick white smoke. By now, the cigar is just about on autopilot. Slow your puffs and simply enjoy the fragrance and having the thing in hand.

To keep it going, puff every minute or so. Cigars can be pretty intense, so treat it like a marathon and not a sprint. Out-puffing your pal will only make you queasy. Some guys prefer to do it right away, and others like to leave it on for the duration of the smoke session. This is up to you, but if you want to remove it, we suggest leaving it on for a few minutes first. As you smoke, your cigar will begin to develop a head of ash on the tip.

You do not need to tap this off like you would with a cigarette. Feel free to leave it there for a while. Too much ash on the end can hinder airflow, which makes to tobacco burn irregularly, and also affects the flavor.

Belicoso Short and set up with a spire-like tip, the Belicoso tends to be a bit shorter and more tapered.
