Brief Summary
This study has the following primary aim: \- the main objective of this study is to investigate the effects of smoking cessation during quit attempts on sympathovagal balance. These effects will be observed in smokers quitting smoking with pharmacological support or without. Secondary aims of this study are also:
- the definition of MSNA in smokers and non-smokers
- the investigation of other parameters concerning the autonomic nervous system, like baroreflex-sensitivity, heart rate-variability before and during the quit attempt.
- the definition of withdrawal symptoms and craving before, during and after the quit attempt.
- the investigation of effects of smoking cues on craving and sympathovagal balance
- the investigation of relapse rates after smoking cessation in correlation with the parameters mentioned above.

Outcome Measures
Primary Outcomes (1)
Assessment of muscular sympathic nervous activity (MSNA) in bursts / 100 heart beats before and while smoking cessation.
Patients present 7 weeks before their personal smoking-stop-day and participate in the study until week 26 after their personal smoking-stop-day. During that time, MSNA is recorded.
33 weeks
Secondary Outcomes (4)
Assessment of the basal sympathetic nerve activity in smokers compared to never-smokers
33 weeks
Assessment of craving and withdrawal symptoms during smoking cessation
33 weeks
Assessment of smoking cues on craving and sympathovagal balance
33 weeks
Assessment of smoking relapse rate
33 weeks

Eligibility Criteria
You may qualify if:
- Men and Women at the age of 25 to 60 years.
- Group A-D: Smokers willing to quit smoking and a FTNA-result \>5.

- Signed consent after information.
You may not qualify if:
- formerly known hypersensitivity against one of the used pharmacological interventions or structurally similar drugs or against one of the ingredients.
- participation in another study during this study or within 4 weeks prior to this study.
- Addiction or other circumstances that prevent the patient from estimating the study and the consequences.
- Pregnancy and breast-feeding
- women with childbearing potential, except women that fulfill the following criteria:
- post menopause
- postoperative (6 weeks after both-sides ovariectomy with or without hysterectomy)
- regular and correct use of prevention methods (error-rate \<1% a year), e.g. implants, depot injections, oral contraceptives, IUP)
- sexual abstinence
- signs that predict a possible non-compliance of the patient
- psoriasis, dermatitis, urticaria
