Onico snus where to buy

There was no significant difference in baseline characteristics for females between those two studies S1 Table. Six women completed study 1 and 23 subjects 12 men and 11 women completed study 2. Study participants used snus for an average of Weekly consumption was 5.

The portion form of snus was used by Women and men used approximately the same amount of snus per week and there was no significant difference in mean age or years of snus usage. There was no difference in baseline values prior to exposure to snus and placebo-control S2 Table. Mean values with standard deviations during 45 minutes of exposure and 30 minutes post exposure to snus or control in males and females.

HR increased significantly within 5 minutes following introduction of snus in females, and it remained significantly elevated during the whole post exposure period of 30 minutes Fig 3. Mean increase in HR in women during the last 25 minutes of exposure was There was no difference when analyzing separately for women and men S2 Fig.

However, when performing single time point analysis with paired samples T-test, women did show a significant increase during the last 25 minutes of exposure for snus S3 Table. For men we observed a significant increase in AiX75 at the end of exposure and during the post-exposure period for placebo S3 Table. Mean values for arterial index adjusted for a heart rate at 75 bpm AiX75 and pulse wave velocity PWV with standard deviations during 45 minutes of exposure and 30 minutes post exposure to snus or control.

Stroke volume index SI significantly decreased 35 minutes following introduction of snus and remained significantly altered 10 minutes into the post exposure period Fig 5. When analyzing with paired samples T-test, this effect was significant at time points 25, 35, 40 and 45min during exposure and during the first 15 minutes into the post exposure period p-values ranging from 0.

All other time points showed no statistical significance. Cardiac index CI did not significantly change over time in either exposure. Mean values with standard deviations during 45 minutes of exposure and 30 minutes post exposure to snus or control. Short exposure to one pouch of snus caused an acute increase in systolic and diastolic blood pressure as well as heart rate in female and male volunteers, however to a lesser extent in males.

Arterial stiffness measurements did not change following exposure in either gender. In a subgroup of female volunteers, snus caused a decreased stroke index as measured by thoracic electrical bioimpedance. To our knowledge, this is the first study on acute vascular response to Swedish snus assessed using pulse wave velocity, pulse wave analysis and thoracic electrical bioimpedance.

Interestingly, in the current study females showed a deviating response to snus use than males. Snus exposure caused a significantly higher HR and BP elevation as compared to men, even though weekly snus consumption was generally the same in both men and women. Hering et al. Indeed, there are clear gender differences in cardiovascular risk in smokers, with a fifty per cent increased risk of myocardial infarction for female smokers as compared to male smokers [ 26 ].

Nicotine stimulates the release of catecholamines from adrenal glands and has a direct sympathomimetic effect on the central nervous system and endothelial function [ 27 , 28 ]. In general, women have a lower resting autonomic nerve activity and react more to catecholamines than men [ 29 ]. This may suggest that gender responses to nicotine could play an underlying key role in the disparate acute hemodynamic responses demonstrated in the current study.

The present study was not primarily designed to investigate gender differences and therefore the results were somewhat surprising. Nevertheless, the observed discrepancy in acute responses to Swedish snus between men and women is highly interesting, as most of the previous cohort studies for the cardiovascular risk of snus use have been solely performed in male subjects [ 6 , 7 , 13 ]. This may be attributed to the fact that the prevalence of snus use is still lower in women as compared to men, as four percent of Swedish women use snus on a daily basis and 5.

However, in the countries where snus is available, there has been a steady increase among female snus users [ 32 ]. More extensive data exists for cigarette use and it has been shown that smoking females have a higher relative risk for myocardial infarction than smoking males [ 26 , 33 , 34 ].

It is important to address this gender difference in future studies to properly assess cardiovascular risk for female snus users. Usage of a snus pouch in the current study gave immediate effects on HR and BP, which is in line with previous findings Rohani, Agewall Similar effects have also been demonstrated following smoking of one cigarette [ 35 , 36 ].

This increase in HR and BP may be attributed to the nicotine content in these tobacco products. Benowitz et al. This theory is further supported by Adamopoulos et al. As mentioned before, nicotine has a direct sympathomimetic effect, which subsequently causes a release of catecholamines [ 27 ].

These catecholamines, specifically epinephrine and norepinephrine, are pro-arrhythmogenic and may also have a pro-thrombotic effect [ 39 — 42 ].

Taken together, the high and prolonged nicotine exposure in snus users may explain the higher incidence of fatal stroke and fatal myocardial infarctions in habitual snus users [ 10 , 13 ]. It may also account for that discontinuation of snus following myocardial infarction reduces mortality by almost fifty per cent [ 9 ]. On the other hand, nicotine replacement therapy NRT does seem to be safe following myocardial infarction and it has not been shown to increase the risk for cardiovascular disease during a follow-up period of 12 months [ 43 , 44 ].

One possible explanation may be that Swedish snus generally has a pH in the range of 7. Increasing the pH increases the portion of free base unprotonated form of nicotine, which accelerates mucosal nicotine absorption. Therefore snus users tend to have higher and more prolonged nicotine absorption than NRT users due to the high pH in snus [ 47 ]. In addition to nicotine, there are several other components found in snus that may cause the demonstrated effect, including polycyclic aromatic hydrocarbons PAHs or aldehydes [ 48 , 49 ].

PAHs are organic chemicals, many of which are classified as carcinogens, which cause damage in the lung tissue when inhaled. However, PAHs can also be ingested or absorbed following dermal and mucosal exposure [ 50 ].

ROS cause oxidative damage to biological structures leading to various diseases including cancer, atherosclerosis and cardiovascular disease [ 51 ]. In the present study we assessed the acute effects on aortic stiffness and distensibility measured by pulse wave analysis and pulse wave velocity. In a similar study, but without placebo-control, AiX75 was shown to increase following exposure to American smokeless tobacco ASLT in a group of habitual users [ 52 ]. ASLT differs from Swedish snus with higher levels of carcinogens like PAHs and aldehydes due to fire curing during manufacturing [ 49 ].

Similar effects with acute increase in arterial stiffness were observed following smoking of one cigarette or administering of one 2mg nicotine tablet [ 35 , 38 ].

In the present study, we investigated daily snus users following a snus-free period of twelve hours. It may be possible that arterial stiffness is chronically altered in snus users due to differences in nicotine delivery compared to smokers or users of nicotine gum.

Snus users tend to have very long exposure times for around 10 hours per day resulting in prolonged high nicotine-levels [ 47 , 53 ]. Chronic exposure slows down nicotine metabolism as compared to what is seen following occasional exposure [ 54 ]. Therefore the prolonged nicotine exposure often seen in snus users may attenuate certain acute effects of nicotine [ 55 ].

As demonstrated in the current study, short-term exposure to snus has an immediate impact on cardiac function and systemic vascular resistance measured using thoracic electrical bioimpedance. This non-invasive method is mostly used to quickly assess cardiac function in a critical care setting, yet is also used in outpatient care settings [ 56 , 57 ].

This observation was seen at a later time-point than the effects on HR and BP. Similar effects on cardiac function were also found following smoking of one cigarette [ 59 ]. As discussed before, it is possible that nicotine exerts these acute effects on cardiac function, but other compounds may play a crucial role. Even though we did not observe any acute effects on arterial stiffness, we found that women had overall higher AiX75, but slightly lower PWV than men.

Similar gender differences have been previously reported in healthy volunteers [ 60 — 62 ]. Physiological differences between men and women, like hormonal or constitutional ones have been discussed as possible explanations for this phenomenon [ 63 , 64 ].

On the other hand, some studies suggest a higher cardiovascular risk for women with elevated arterial index compared to men [ 65 , 66 ]. Our study participants were habitual snus-users and we observed no differences in snus consumption between males and females. Accordingly, differences in snus consumption cannot explain this finding. The fact that women had overall higher arterial stiffness and a higher acute hemodynamic response to acute snus exposure suggests strongly that the cardiovascular risk for snus using women needs to be further elucidated.

This study was not designed to investigate gender differences. Therefore results have to be interpreted with caution. Data from two studies was pooled for analysis. Even though we had identical study designs, two separate investigators performed arterial stiffness measurements. Thoracic electrical bioimpedance measurements were only performed in the six female subjects in study 1.

A study involving more study participants including male volunteers would strengthen our thoracic electrical bioimpedance results. Brief exposure to Swedish snus causes acute changes in blood pressure and heart rate, however this change is more pronounced in females. The novel finding that snus may have different gender related vascular effects needs to be further investigated, especially as prior health effect studies have mostly focused on males.

Mean values for arterial index adjusted for a heart rate at 75 bpm AiX75 and pulse wave velocity PWV with standard deviations during 45 minutes of exposure and 30 minutes post exposure to snus or control, separated for males and females.

Freddi Lewin, health advisor at Swedish Match, said the company had been contacted by two dentists in the past month saying patients using the product had developed cavities, and also by consumers with similar concerns.

The firm said it was taking the information seriously and had initiated an analysis of the production and the ingredients of the product, Onico, which is based on corn fibre. There are no indications at this point that this is a big problem.
