Understanding And Addressing Nicotine Addiction: A Science-Based Approach to ...Center on Addiction
Nicotine is a highly addictive substance that not only perpetuates tobacco use, the leading cause of preventable morbidity and mortality in the United States, but also has its own adverse effects. Nicotine addiction is a chronic and relapsing disease and the prevalence of nicotine addiction is higher than that of alcohol and other drug addiction. The use of nicotine-containing products not only is associated with developing nicotine addiction, but also with using and becoming addicted to alcohol and other drugs.
Despite the decline in recent years in the use of cigarettes, the use of alternative, non-cigarette nicotine products has been rising dramatically. While the overall harm of these products appears to be considerably lower than the harms associated with cigarette use, all nicotine-containing products carry the risk of addiction and other adverse health effects and, therefore, are a threat to the public health.
In general Tobacco is always considered to be useful for its nicotine content. but there are far more important uses of it, such as in medicinal fields.

Pulse Publish a post CYP2A6 Genes Polymorphism Roles in Nicotine Depende...Yawo Akrodou
Functionally genes provide the information that governs the basic biologic and physiological activities of cells conditioning our behavior in relationship with our environment changes. CYP2A6 variants variably inhibit and reduce nicotine dependence and play a significant role in nicotine uptake, distribution, and clearance, implying their clinical potential. Also, CYP2A6 variants have been linked to smoking behavior, nicotine-dependence development, and treatment in epidemiological quantitative and human laboratory studies. It appears in this current study that CYP2A6 variants’ enzymatic activities are correlated to variation in smoking behaviors and are implicated in nicotine treatments as they are capable of metabolizing nicotine, and medication use in nicotine addiction treatment.
Tobacco use can lead to nicotine dependence and serious health problems. Cessation can significantly reduce the risk of suffering from smoking-related diseases. Tobacco dependence is a chronic condition that often requires repeated interventions, but effective treatments and helpful resources exist. Smokers can and do quit smoking. In fact, today there are more former smokers than current smokers.

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting

CDSCO and Phamacovigilance {Regulatory body in India}NEHA GUPTA
The Central Drugs Standard Control Organization (CDSCO) is India's national regulatory body for pharmaceuticals and medical devices. Operating under the Directorate General of Health Services, Ministry of Health & Family Welfare, Government of India, the CDSCO is responsible for approving new drugs, conducting clinical trials, setting standards for drugs, controlling the quality of imported drugs, and coordinating the activities of State Drug Control Organizations by providing expert advice.
Pharmacovigilance, on the other hand, is the science and activities related to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems. The primary aim of pharmacovigilance is to ensure the safety and efficacy of medicines, thereby protecting public health.
In India, pharmacovigilance activities are monitored by the Pharmacovigilance Programme of India (PvPI), which works closely with CDSCO to collect, analyze, and act upon data regarding adverse drug reactions (ADRs). Together, they play a critical role in ensuring that the benefits of drugs outweigh their risks, maintaining high standards of patient safety, and promoting the rational use of medicines.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

3. Facts about Smoking
Most of those killed by tobacco are not particularly heavy smokers
and most started as teenagers.
Approximately 50 percent of smokers die prematurely from their
smoking, on average 14 years earlier than non-smokers.
Smoking kills one in two of those who continue to smoke past age
35.
There is evidence that smoking can cause about 40 different
diseases.
the preventable mortality attributed to smoking is 8 percent of
deaths in females and 19 percent in males.
Smoking is socioeconomically patterned with higher rates of
smoking in lower socio-economic groups. Thus tobacco smoking
produces a greater relative burden of disease and premature death
in lower socioeconomic groups and is a major contributor to
socioeconomic inequalities in health.
4. Facts (cont.)
Smoking, especially current smoking, is a crucial and
extremely modifiable independent determinant of
stroke.
Second-hand smoke (also called environmental tobacco
smoke) is a Class A carcinogen and contains
approximately 4,000 chemicals.
Exposure of children to second-hand smoke:
▫ can cause middle ear effusion
▫ increases the risk of croup, pneumonia and bronchiolitis by 60
percent in the first 18 months of life
▫ increases the frequency and severity of asthma episodes
▫ is a risk factor for induction of asthma in asymptomatic children.
5. Benefits of Smoking Cessation
These points may be helpful in motivating people to quit
smoking. Many smokers deny being at increased risk of
cancer and heart disease and more accurate perception of
risk may assist cessation efforts.
It is beneficial to stop smoking at any age. The earlier smoking is
stopped, the greater the health gain.
Smoking cessation has major and immediate health benefits for
smokers of all ages. Former smokers have fewer days of illness, fewer
health complaints, and view themselves as healthier.
Within one day of quitting, the chance of a heart attack decreases.
Within two days of quitting, smell and taste are enhanced.
Within two weeks to three months of quitting, circulation
improves and lung function increases by up to 30 percent.
6. Excess risk of heart disease is reduced by half after one
year’s abstinence. The risk of a major coronary event
reduces to the level of a never smoker within five years. In
those with existing heart disease, cessation reduces the risk
of recurrent infarction or death by half.
Former smokers live longer: after 10 to 15 years’
abstinence, the risk of dying almost returns to that of
people who never smoked. Smoking cessation at all ages,
including in older people, reduces risk of premature death.
Men who smoke are 17 times more likely than non-smokers
to develop lung cancer. After 10 years’ abstinence, former
smokers’ risk is only 30 to 50 percent that of continuing
smokers, and continues to decline.
7. Women who stop smoking before or during the
first trimester of pregnancy reduce risks to their
baby to a level comparable to that of women who
have never smoked. Around one in four low
birth weight infants could be prevented by
eliminating smoking during pregnancy.
The average weight gain of three kg and the
adverse temporary psychological effects of
quitting are far outweighed by the health
benefits.
8. Evidence for Effectiveness of Health
Professional Intervention
A Cochrane review of 16 RCTs found simple advice from doctors had a
significant effect on cessation rates (OR for quitting 1.69; 95%
confidence interval 1.45–1.98).
When trained providers are routinely prompted to intervene with
people who smoke, they achieve significant reductions in smoking
prevalence (up to 15 percent cessation rates compared with 5 to 10
percent in non-intervention sites).
Doctors and other health professionals using multiple types of
intervention to deliver individualized advice on multiple occasions
produce the best results. Frequent and consistent interventions over
time are more important than the type of intervention.
9. Smoking Cessation Program
The only way any country can substantially
reduce smoking and other tobacco use within its
borders is to establish a well-funded and
sustained comprehensive tobacco prevention
program that employs a variety of effective
approaches.
Nothing else will successfully compete against
the addictive power of nicotine and the tobacco
industry's aggressive marketing tactics.
10. ESSENTIAL COMPONENTS
The following elements must all be included to maximize
the success of any program to reduce tobacco use.
Conducted in isolation, each of these elements can reduce
tobacco use, but done together they have a much more
powerful impact:
Public Education Efforts
Community-Based Programs
Helping Smokers Quit (Cessation)
School-Based Programs
Enforcement
Monitoring and Evaluation
Related Policy Efforts
12. Tobacco dependence is a chronic condition that
often requires repeated intervention. However,
effective treatments exist that can produce longterm abstinence.
These guidelines are designed for smoking
cessation providers to assist all clients with
smoking cessation.

Medication Blood Levels
Smoking
induces the P450’s 1A2 isoenzyme
secondary to the polynuclear aromatic hydrocarbons
Smoking increases the metabolism of some
medications
–
Haldol, Prolixin, Olanzapine, Clozapine, Mellaril, Thorazine, etc
Caffeine
is metabolized through 1A2
CHECK for medication SE or relapse to mental
illness with changes in smoking status
Nicotine does not change medication blood levels
(2D6)
NRT doesn’t affect medication blood levels
Nicotine may modulate cognition, psychiatric
symptoms, and medication side effects

47. Conclusions
47
Nicotine Replacement Therapy is being
provided to assist tobacco users to
become tobacco free.
NRT is not a treatment in itself, but is
intended to complement the other
assessments and treatments provided.
NRT works by reducing craving and
withdrawal severity, enabling the
patient to feel comfortable and able to
concentrate on other psychosocial
treatments.

60. Smoking & Bipolar Disorder
High
prevalence of smoking: 61-80%
Findings are inconsistent regarding
the prevalence of smoking between
bipolar disorder with and without
psychotic features
Bupropion is contraindicated
Quit rates are comparable to general
population and durable
Quit rates enhanced with CBT

61. Smoking and Depression
The
prevalence of smoking: 37-60%
Leads to more severe nicotine withdrawal
symptoms
- High
risk for relapse in first week
- Female > Male
30%
risk of relapse to MDE after quitting if
past history present
Depressed smokers have higher suicide
rates than depressed nonsmokers
(Bruce, 1994; Lohr, 1992; Yassa, 1987)

63. Smoking and Depression (Continued)
NRT
63
alone insufficient treatment for
smokers with current and/or past MDD
Combining NRT with non-NRT
pharmacotherapy appear to be promising
for smokers with depression (Ait-Daoud
et al., 2006)
CBT that emphasizes group cohesion
and social support appears to be
particularly effective for depressed
smokers with or without alcohol
dependence
64. Smoking and Anxiety D/O
The
prevalence of smoking: About 35-50%
Smokers have greater anxiety and panic symptoms
than non-smokers
Heavy smoking in adolescent is associated with
higher risk of developing Agoraphobia, GAD, and
Panic Disorder
PTSD:
–
–
–
64
Increased risk for relapse in first two weeks of quit attempt
– Increased the risk of smoking and nicotine dependence
lower rates for quitting smoking & remission from nicotine
dependence
Stopping smoking not associated with worsening of PTSD
– Bupropion tolerated and effective treatment
65. SSRIs and Smokers with
Anxiety Disorder
No
benefit for smoking cessation
Can reduce likelihood of emergent
anxiety and panic during quit attempt
Bupropion is not appropriate as only
medication
Can be combined with NRT/Bupuropion
Can be combined with varnicline
65
66. Smoking and Alcohol
Dependence
High
prevalence of smoking: 80-95%
Two studies reporting similar outcomes
of NRT in alcoholics compared with nonalcoholics (e.g., Grant et al., Alcohol,
2007)
Tobacco dependence treatment does
not cause abstinent alcoholics to
relapse (Hughes & Callas, 2003)
Smoking cessation reduces the risk of
alcohol relapse (Sobell et al., 1995)
66
67. Smoking and Alcohol Dependence
(Continued)
Bupropion
added to nicotine patch did
not improve smoking outcomes
Topiramate group was significantly
more likely to become abstinent (OR =
4.46) compared with placebo group
(Johnson et al., 2003)
Topiramate group reported more weight
loss compared with placebo group
(44% vs. 18%)

70. Future Medication Options
FDA. Rimonabant is a cannabinoid receptor inhibitor
that blocks the reinforcing effects of nicotine and also
suppresses appetite. Now in phase 3 trials, it has
already receive much attention for its potential to
attack 2 major public health epidemics; smoking and
obesity.
73. E-cigarettes were found to have immediate
adverse physiologic effects after short time use
that are similar to some of the effects seen with
tobacco smoking ; however, the long term health
effects of e-cigarette use are unknown but
potentially adverse effects are worthy of further
investigation.

Medications used in tobacco dependence treatment are classified as first-line and second-line medications depending on how safe and effective they are. Except for sustained release Bupropion all medications classified as first-line replace the mode of nicotine delivery, so they are called nicotine replacement therapy.
