    How Can I Resist The Urge To Smoke When Im Feeling Stressed

    Most smokers report that one reason they smoke is to handle stress. This happens because smoking cigarettes actually relieves some of your stress by releasing powerful chemicals in your brain. Temporary changes in brain chemistry cause you to experience decreased anxiety, enhanced pleasure, and alert relaxation. Once you stop smoking, you may become more aware of stress.

    Everyday worries, responsibilities, and hassles can all contribute to stress. As you go longer without smoking, you will get better at handling stress, especially if you learn stress reduction and relaxation techniques.

    Here are some tips:

    • Know the causes of stress in your life and identify the stress signals . Once you pinpoint high-risk trigger situations, you can start to develop new ways to handle them.
    • Create peaceful times in your everyday schedule. For example, set aside an hour where you can get away from other people and your usual environment.
    • Try relaxation techniques, such as progressive relaxation or yoga, and stick with the one that works best for you.
    • Rehearse and visualize your relaxation plan. Put your plan into action. Change your plan as needed.
    • You may find it helpful to read a book about how to handle stress.

    How You Can Help

    Next, its important to have a conversation with your teen about vaping and it should be a conversation, not a lecture. Here are some suggestions on how to approach the subject:

  • Find a natural conversation starter. Maybe its an ad for e-cigarettes, or you notice someone vaping. Ask your teen questions about vaping, and whether a lot of kids at their school are trying it.
  • Explain that most e-cigarettes do contain nicotine. Some teens believe, because of marketing messages, that e-cigarettes contain only water and flavoring. Research proves otherwise.
  • Point out the dangers of vaping without judgment. Send them a link to the science that shows vaping exposes users to harmful chemicals and increases their risk of addiction.
  • Have them calculate the monthly cost of vaping: It can range from $50-$120.
  • Keep the conversation going. This isnt a one-and-done topic. Discuss vaping often and calmly. And if you need additional support, consider asking a health care professional to talk to your teen about the risks of e-cigarettes.
  • The truth is, you cant force your teen to quit vaping. But your influence can make a difference. Mr. Bynum says his mom played a big part in getting him to attend the nicotine cessation program at UT Southwestern. She was worried for me, he says.

    “The U.S. Surgeon General notes that addiction is especially risky for teens and young adults, because the brain is more vulnerable to addiction while its still developing, through about age 25.”

    Tobacco Nicotine And E

    The smoke from combustible tobacco products contains more than 7,000 chemicals. Nicotine is the primary reinforcing component of tobacco it drives tobacco addiction.20,21 Hundreds of compounds are added to tobacco to enhance its flavor and the absorption of nicotine.22 Cigarette smoking is the most popular method of using tobacco however, many people also use smokeless tobacco products, such as snuff and chewing tobacco, which also contain nicotine . E-cigarettes, which deliver nicotine in the absence of other chemicals in tobacco, have become popular in recent years .

    The cigarette is a very efficient and highly engineered drug-delivery system. By inhaling tobacco smoke, the average smoker takes in 12 milligrams of nicotine per cigarette. When tobacco is smoked, nicotine rapidly reaches peak levels in the bloodstream and enters the brain. A typical smoker will take 10 puffs on a cigarette over the roughly 5 minutes that the cigarette is lit.23 Thus, a person who smokes about 1 pack daily gets 200 “hits” of nicotine to the brain each day. Among those who do not inhale the smokesuch as cigar and pipe smokers and smokeless tobacco usersnicotine is absorbed through mucous membranes in the mouth and reaches peak blood and brain levels more slowly.

    The Implications Of Laboratory Studies For Our Understanding Of Psychopharmacology And Treatment Of Tobacco Dependence

    How does nicotine work

    Another non-nicotinic approach that has proved valuable is bupropion. The efficacy of bupropion as an aid to smoking cessation was discovered serendipitously and the psychobiology underlying its efficacy in this indication remains the subject of debate. This compound, or its active metabolites, potentiate the effects of norepinephrine and DA in the brain by blocking the transporters which re-accumulate these neurotransmitters into the nerve terminals, and it is assumed that this effect is important to its mechanism of action as an aid to smoking cessation . If this is true, it seems reasonable to hypothesise that the compound works by alleviating some of the consequences of nicotine/tobacco withdrawal through its effects on these pathways, perhaps most notably the anhedonia experienced by many abstinent smokers. Recent studies with experimental animals provided some support for this hypothesis, to the extent that the compound attenuates the anhedonia measured in nicotine abstinent rats . Bupropion also attenuates the somatic consequences of nicotine withdrawal . Interestingly, in animals allowed to self-administer nicotine, bupropion did not reduce responses for the drug although it did diminish the increase in brain reward function exhibited by these animals, suggesting a dissociation between these two responses to the drug .

    The Science Of Nicotine Addiction


    The news made headlines in 2006: Smokers today get more nicotine from inhaling cigarette smoke than they did in 1998. The news is alarming because nicotine is the chemical in cigarette smoke that causes addiction to tobacco. The Massachusetts Department of Public Health reported its discovery that the nicotine yield in cigarettesmeaning the amount of nicotine a smoker gets from a cigarettehad increased steadily between 1998 and 2004. The DPH used information provided by tobacco companies themselves.

    One deadly consequence of more nicotine yield in cigarettes is that the average smoker will find it harder to quit. Not only is there more nicotine in cigarettes, but nicotine itself is a powerfully addictive drug. In the words of a NIDA-funded researcher, Dr. Daniel McGehee: “It would be difficult to design a better drug to promote addiction.”

    Why Nicotine Is So Addictive In investigating the addictive power of nicotine, NIDA-funded researchers at the University of Chicago found that nicotine’s effect on the brain is doubly dangerous. It directly stimulates the feelings of pleasure and indirectly keeps those pleasurable feelings going strong.

    To explain why dopamine levels remain high after direct nicotine stimulus ends, researchers looked at two other neurotransmitters in the brain, glutamate and GABA. Glutamate is a neurotransmitter that speeds up the activity of neurons. GABA is a neurotransmitter that slows down neuron activity.

    What Does A Nicotine Craving Feel Like

    Craving cigarettes, feeling sad or irritable, or trouble sleeping are some common symptoms. Some people say it feels like a mild case of the flu. For most people, the worst symptoms last a few days to a few weeks. Managing withdrawal symptoms will help you feel better and be prepared for those tougher moments.

    Psychoactive Effects Of Nicotine And Nicotine Withdrawal

    In humans, nicotine from tobacco induces stimulation and pleasure, and reduces stress and anxiety. Smokers come to use nicotine to modulate their level of arousal and for mood control in daily life. Smoking may improve concentration, reaction time, and performance of certain tasks. When a person stops smoking, nicotine withdrawal symptoms emerge. These include irritability, depressed mood, restlessness, anxiety, problems getting along with friends and family, difficulty concentrating, increased hunger and eating, insomnia, and craving for tobacco . Nicotine withdrawal in untreated smokers produces mood disturbances comparable in intensity to those seen in psychiatric outpatients . Hedonic dysregulation, the feeling that there is little pleasure in life and that activities that were once rewarding are no longer enjoyable, is seen with withdrawal from nicotine and from other drugs of abuse . It is hypothesized that a relative deficiency in dopamine release following long-standing nicotine exposure accounts for many of the mood disorders and the anhedonia, as well as the tobacco craving, that may persist in smokers for a long time after they have quit.

    Why Is Nicotine Addictive

    The first cigarette you smoke wont always be pleasant. Many people report feeling dizzy and having an upset stomach. These feelings may be accompanied by a headache too. However, as you continue to smoke, your body builds resistance to the drug, and the effects are no longer bothersome.

    The body quickly builds tolerance and needs more to bring the same euphoric feeling. Once you set a pattern and smoke so many cigarettes each day, your body learns to adjust, and it craves that same level of nicotine to function. The pleasurable effects are hard to live without.

    Additionally, the addiction disrupts the bodys natural balance, and without cigarettes, you will no longer feel normal. Just like any other addiction, there are many psychological components as well as physical ones.

    What Are Some Of The Withdrawal Symptoms Associated With Quitting Smoking

    How Nicotine Works

    Quitting smoking may cause short-term problems, especially for those who have smoked heavily for many years. These temporary changes can result in withdrawal symptoms.

    Common withdrawal symptoms associated with quitting include the following:

    • nicotine cravings
    • anger, frustration, and irritability
    • depression
    • weight gain

    Studies have shown that about half of smokers report experiencing at least four withdrawal symptoms when they quit . People have reported other symptoms, including dizziness, increased dreaming, and headaches .

    The good news is that there is much you can do to reduce cravings and manage common withdrawal symptoms. Even without medication, withdrawal symptoms and other problems subside over time. It may also help to know that withdrawal symptoms are usually worst during the first week after quitting. From that point on, the intensity usually drops over the first month. However, everyone is different, and some people have withdrawal symptoms for several months after quitting .

    What Can I Do About Depression

    It is normal to feel sad for a period of time after you first quit smoking. If mild depression occurs, it will usually begin within the first day, continue for the first couple of weeks, and go away within a month.

    Having a history of depression is associated with more severe withdrawal symptomsâincluding more severe depression. Some studies have found that many people with a history of major depression will have a new major depressive episode after quitting. However, in those with no history of depression, major depression after quitting is rare.

    Many people have a strong urge to smoke when they feel depressed. Here are some tips for managing depression:

    • Identify your specific feelings at the time that you seem depressed. Are you actually feeling tired, lonely, bored, or hungry? Focus on and address these specific needs.
    • Increase physical activity. This will help to improve your mood and lift your depression.
    • Breathe deeply.
    • Make a list of things that are upsetting to you and write down solutions for them.
    • If depression continues for more than 1 month, see your doctor. Ask your doctor about prescription medications that may help you with depression. Studies show that bupropion and nortriptyline can help people with a past history of depression who try to quit smoking. Nicotine replacement products also help .
    • Learn about the signs of depression, and where to go for help, at the National Institute of Mental Health website.

    How Can I Resist The Urge To Smoke When Im Around Smokers

    Here are some tips:

    • Limit your contact with smokers, especially in the early weeks of quitting.
    • Do not buy, carry, light, or hold cigarettes for others.
    • If you are in a group and others light up, excuse yourself, and donât return until they have finished.

    • Ask others to help you stay quit. Give them specific examples of things that are helpful and things that are not helpful .
    • Focus on what youâve gained by quitting. For example, think of how healthy you will be when all smoking effects are gone from your body and you can call yourself smoke-free. Also, add up how much money you have saved already by not purchasing cigarettes and imagine how you will spend your savings in 6 months.
