Title: Smoking Cessation Via Text Messaging: Feasibility Testing of SMS USA
Brief Summary: The investigators developed a text messaging-based smoking cessation program called SMS (Stop My Smoking) USA. It was tailored for the unique needs and smoking habits of young adults. The investigators hypothesized that those in the SMS USA intervention would be significantly more likely to be quit at 6-months compared to the attention-matched control group.


Options:
A: Inclusion Criteria:

* 28 cigarettes or more per week (at least 4/day) and on at least 6 days/week.
* Owning a text-capable cell phone and cognizant of how to send and receive text messages
* Currently enrolled or intending to enroll in an unlimited text messaging plan
* Enrolled with a cell phone carrier that was compatible with the program software
* Agree to verification of smoking cessation status by a significant other
* Able to read and write in English
* Informed consent

Exclusion Criteria:

None
B: Inclusion Criteria:

* Students from Germany aged 9 to 14 years at baseline attending grades six and seven of regular German secondary schools (such as grammar, general, intermediate or comprehensive school) are eligible.

Exclusion Criteria:

* Older or younger pupils or pupils from other school types or countries or schools who previously participated in an event where the Smokerface app was presented are not eligible.
C: Inclusion Criteria:

1. Regular cigarette smokers smoking at least 5 cigarettes per day as derived by Time-Line Follow-Back method (Sobell et al., 1988). Average number of cigarettes per day (over past 30 days) will be used. Five cigarettes per day may seem low, but based on previous studies, adolescents tend to smoke fewer cigarettes per day as compared to adults.
2. Baseline urine cotinine level greater than 100 ng/ml.
3. Age range of 12 - 21
4. If under 18 yr. of age, parent(s) or guardian(s) able to participate in informed consent and initial assessment, or the participant must provide evidence of emancipated status.
5. For post menarchal female participants: agree to use birth control to avoid pregnancy.

Exclusion Criteria:

1. Active substance abuse/dependence (other than nicotine) within 2 weeks prior to participating in the study
2. Lifetime bipolar affective disorder (BPAD), psychosis, eating disorders. Bupropion may have adverse consequence on participants with these psychiatric diagnoses.
3. Current major depressive disorders. Since bupropion is also an antidepressant, this criteria is to minimize the confound of depressive disorder during the study. History of depressive disorders and current attention deficit hyperactivity disorder (ADHD) will not be an exclusion. We will use permuted block randomization procedure to balance the groups for ADHD.
4. Pregnancy or lactation. The safety of bupropion in pregnancy and during lactation is not well studied.
5. History of seizure disorder or predisposition to seizures (e.g., history of significant head trauma, currently taking medications that lower seizure threshold), since bupropion can lower seizure threshold.
6. History of severe renal, hepatic, neurological, or chronic pulmonary disease. This criterion was chosen due to the hepatic metabolism of bupropion.
7. Unstable medical problems
8. Allergy to bupropion
9. Current treatment with any other medication containing bupropion
10. Current treatment with any monoamine oxidase (MAO) inhibitors currently or within 2 weeks of starting the study since there may be serious and severe medical interactions between MAO inhibitors and bupropion SR.
11. Current treatment with nicotine replacement therapy (NRT)
12. History of intolerance or non-response to bupropion SR.
13. Current (past month) suicide ideation
14. Suicide attempt (past year)
D: Inclusion Criteria:

* Healthy male and female adolescents (12 - 16 years inclusive) with a total body weight greater than 30 kg who currently smoke an average of at least 3 cigarettes per day.

Exclusion Criteria:

* Male and female subjects with a positive urine drug screen and female subjects with a positive pregnancy test.
