Secondhand Smoke


Emma's friend Megan lights up a cigarette every chance she gets — while she's cruising around with their friends on Friday nights, during breaks at the pizza place, before soccer scrimmages, even as she babysits her brother. Emma's worried — both for her friend's health and for her own. She's not sure Megan realizes how her habit could be affecting the health of the people she smokes around.

Everyone knows smoking is a bad idea. And by now you've probably heard that breathing in someone else's secondhand smoke is also hazardous to your health.

What Is Secondhand Smoke?

Secondhand smoke comes from both the smoke that smokers exhale (called mainstream smoke) and the smoke floating from the end of the cigarette, cigar, or pipe (called sidestream smoke).

It may seem pretty harmless, but secondhand smoke actually contains thousands of chemicals — from arsenic and ammonia to hydrogen cyanide — many of which have been proven to be toxic or to cause cancer (called carcinogens). High concentrations of many of these chemicals are found in secondhand smoke. In fact, secondhand smoke significantly increases a person's risk for:

  • respiratory infections (like bronchitis and pneumonia)
  • asthma (secondhand smoke is a risk factor for the development of asthma and can trigger attacks in those who already have it)
  • coughing, sore throats, sniffling, and sneezing
  • cancer
  • heart disease

So secondhand smoke doesn't just impact a person in the future. It can cause problems right now, like affecting someone's sports performance or ability to be physically active.

Inhalants


Most people think harmful drugs are only found on street corners or in local pharmacies, not cleaning cabinets or garages.

But sometimes items commonly found in millions of homes aren't used for their intended purposes. Some people inhale the chemical vapors produced by common household substances — known as inhalants — to get high. What many of them don't realize is how dangerous this really is.

Why People Use Inhalants

Inhalants might seem like an alternative to other mood-altering drugs because they are cheap, can be purchased legally, and are easy to obtain. But that doesn't make them safer. When used as directed, household products are safe for cleaning, painting, and the other things they're meant to do. But as inhalants, they can be deadlier than street drugs.

Different Kinds of Inhalants

There are four main types of inhalants: volatile solvents, gases, aerosols, and nitrites. Volatile solvents, gases, and aerosols can alter moods and create a high. Nitrites are believed to create sexual stimulation and enhancement.

Here is what else you need to know about the types of inhalants:

  • Volatile solvents are liquids that become a gas at room temperature. Some examples are paint thinners and removers, gasoline, glues, and felt-tip marker fluids.
  • Gases include medical gases (ether, nitrous oxide) and household or commercial products (butane lighters, propane tanks, whipped cream dispensers that contain nitrous oxide, and refrigerants).
  • Aerosol sprays are some of the most prevalent inhalants in the home and include spray paint, deodorant and hairsprays, vegetable oil cooking sprays, and static cling sprays.
  • Nitrites include cyclohexyl nitrite, amyl nitrite, and butyl nitrite. On the street, they're called "poppers" or "snappers." They're found in some room deodorizers and capsules that release vapors when opened.

Effects on the Body

People inhale chemical vapors in several ways, including sniffing, snorting, or spraying the inhalant directly into the nose or mouth, putting it into a bag or other container and then inhaling from there, putting the vapor onto a rag, or inhaling nitrous oxide from balloons.

Because the high from inhalants only lasts a few minutes, some people may inhale over and over again for long periods of time to maintain the high, increasing the amount of dangerous chemicals entering and damaging the body.

Inhalants can cause many changes in the body. Once the vapors enter the body, some are absorbed by parts of the brain and nervous system. All of the inhalants (except nitrites) slow down the body's functions, similar to the effects of drinking alcohol. At first someone gets excited, but then gets tired, has trouble speaking clearly or walking well, gets dizzy, loses inhibitions, and may get agitated. It can sometimes take up to 2 weeks for the chemical to completely pass from the body.

Other short-term effects of inhaling chemicals include:

  • increased heart rate
  • hallucinations or delusions
  • losing feeling or consciousness
  • nausea and vomiting
  • loss of coordination
  • slurred speech

Because inhalants are found in most homes, people don't realize they are incredibly addictive. People who become addicted to using inhalants are likely to become long-term users. This puts them at risk for these health problems:

  • brain damage (toxic chemicals may make people become slow or clumsy, have trouble solving problems or planning ahead, suffer from memory loss, or become unable to learn new things)
  • muscle weakness
  • depression
  • headaches and nosebleeds
  • loss of sense of smell or hearing

Nitrites work differently. Instead of slowing down the brain and the spinal cord, they increase the size of blood vessels and relax the muscles.

How Inhalants Kill

Like most street drugs, inhalants can be deadly. Someone can die from abusing inhalants after trying it only once. Causes of death include:

  • "Sudden Sniffing Death" — This is the most common cause of death from inhalant use. The heart beats quickly and irregularly, and then suddenly stops (cardiac arrest). This can happen even the first time a person tries an inhalant and is experimenting.
  • Asphyxia — Toxic fumes replace oxygen in the lungs so that a person stops breathing.
  • Choking — A user can choke on his or her vomit.
  • Suffocation — When vapors are inhaled from a plastic bag placed over the head, the bag can block air from entering the lungs.
  • Injuries — Since people high on inhalants often make poor decisions, they might try to drive under the influence or do something irrational, such as jump off a roof. They could also get burned or start explosions if a spark ignites flammable inhalants.
  • Suicide — Some people become depressed when their high wears off.

Signs of Inhalant Abuse

Inhalants, like other drugs, have noticeable effects on those using them. Someone on inhalants may suffer from a number of different ill effects, including:

  • mood swings
  • extreme anger, agitation, and irritability
  • exhaustion
  • loss of appetite
  • frequent vomiting
  • hallucinations and illusions
  • facial rashes and blisters
  • frequent runny nose and cough
  • dilated pupils
  • glazed or watery eyes
  • extremely bad breath

Of course, some of these things are signs of other health problems, not necessarily inhalant use. If you're worried about a friend or loved one, talk to a parent, school counselor, or your doctor or school nurse.

Getting Help

If you think you — or a friend — may be addicted to inhalants, talk to your doctor, school counselor, or nurse. They can help you get the help you need.

Several kinds of treatment are available for drug addiction; the two main categories are behavioral (helping a person change behaviors) and pharmacological (treating a person with medication).

Treatment for inhalant addiction is primarily behavioral. An expert in drug treatment teaches people how to function without drugs — handling cravings, avoiding situations that could lead to inhalant use, and preventing and handling relapses.

As with any addiction, it can be difficult to stop without professional help and treatment. Overcoming an addiction is not something that can be done alone; everyone needs support. The experts who help people with addictions are trained to help, not judge. To find a drug treatment center in your area, check online, check out the yellow pages, or ask a counselor for advice.

Dealing With Addiction


Jason's life is beginning to unravel. His grades have slipped, he's moody, he doesn't talk to his friends, and he has stopped showing up for practice. Jason's friends know he has been experimenting with drugs and now they're worried he has become addicted.

Defining an addiction is tricky, and knowing how to handle one is even harder.

What Are Substance Abuse and Addiction?

The difference between substance abuse and addiction is very slight. Substance abuse means using an illegal substance or using a legal substance in the wrong way. Addiction begins as abuse, or using a substance like marijuana or cocaine.

You can abuse a drug (or alcohol) without having an addiction. For example, just because Sara smoked pot a few times doesn't mean that she has an addiction, but it does mean that she's abusing a drug — and that could lead to an addiction.

People can get addicted to all sorts of substances. When we think of addiction, we usually think of alcohol or illegal drugs. But people become addicted to medications, cigarettes, even glue!

And some substances are more addictive than others: Drugs like crack or heroin are so addictive that they might only be used once or twice before the user loses control.

Addiction means a person has no control over whether he or she uses a drug or drinks. Someone who's addicted to cocaine has grown so used to the drug that he or she has to have it. Addiction can be physical, psychological, or both.

Physical Addiction

Being physically addicted means a person's body actually becomes dependent on a particular substance (even smoking is physically addictive). It also means building tolerance to that substance, so that a person needs a larger dose than ever before to get the same effects.

Someone who is physically addicted and stops using a substance like drugs, alcohol, or cigarettes may experience withdrawal symptoms. Common symptoms of withdrawal are diarrhea, shaking, and generally feeling awful.

I Think I May Have a Drinking/Drug Problem. What Should I Do?


My friend thinks I have a drinking and drug problem. What should I do?
- Taylor*

Using alcohol or drugs regularly is usually just a step away from addiction (where you depend on these substances to feel good or get through your day).

Here are a few warning signs that someone may have a substance abuse problem:

  • relying on drugs or alcohol to have fun, forget problems, or relax
  • having blackouts
  • drinking or using drugs while alone
  • withdrawing or keeping secrets from friends or family
  • losing interest in activities that used to be important
  • performing differently in school (such as grades dropping and frequent absences)
  • building an increased tolerance to alcohol or drugs — gradually needing more and more of the substance to get the same feeling
  • lying, stealing, or selling stuff to get money for drugs or alcohol

It's usually hard for people to recognize they have a problem, which is why friends or family often step in. Quitting is hard to do, and many people find they can't do it without help. The best thing you can do is to talk to someone you trust — preferably an adult who can support you — so you don't have to deal with your problem alone.

Lots of resources are available for people with substance abuse problems. Alcoholics Anonymous and Narcotics Anonymous offer information and recovery programs for teens. The Alcohol and Drug Information hotline is (800) 729-6686.

Prescription Drug Abuse


Angie overheard her parents talking about how her brother's ADHD medicine was making him less hungry. Because Angie was worried about her weight, she started sneaking one of her brother's pills every few days.

Todd found an old bottle of painkillers that had been left over from his dad's operation. He decided to try them. Because a doctor had prescribed the pills, Todd figured that meant they'd be OK to try.

Both Todd and Angie are taking risks. Prescription painkillers and other medications help lots of people live more productive lives, freeing them from the symptoms of medical conditions like depression or attention deficit hyperactivity disorder (ADHD). But that's only when they're prescribed for a particular individual to treat a specific condition.

Taking prescription drugs in a way that hasn't been recommended by a doctor can be more dangerous than people think. In fact, it's drug abuse. And it's just as illegal as taking street drugs.

Why Do Some People Abuse Prescription Drugs?

drug poisoning

Some people experiment with prescription drugs because they think they will help them have more fun, lose weight, fit in, and even study more effectively. Prescription drugs can be easier to get than street drugs: Family members or friends may have them. But prescription drugs are also sometimes sold on the street like other illegal drugs.

Prescription drug abuse continues to rise. In 2012, 24% of teens surveyed said they have taken a prescription drug without a doctor's prescription.

Why? Some people think that prescription drugs are safer and less addictive than street drugs. After all, these are drugs that moms, dads, and even kid brothers and sisters use. To Angie, taking her brother's ADHD medicine felt like a good way to keep her appetite in check. She'd heard how bad diet pills can be, and she wrongly thought that the ADHD drugs would be safer.

But prescription drugs are only safe for the individuals who actually have prescriptions for them. That's because a doctor has examined these people and prescribed the right dose of medication for a specific medical condition. The doctor has also told them exactly how they should take the medicine, including things to avoid while taking the drug — such as drinking alcohol, smoking, or taking other medications. They also are aware of potentially dangerous side effects and can monitor patients closely for these.

Other people who try prescription drugs are like Todd. They think they're not doing anything illegal because these drugs are prescribed by doctors. But taking drugs without a prescription — or sharing a prescription drug with friends — is actually breaking the law.

5 Facts About Goal Setting


5 Facts About Goal Setting

Lee este articulo

These practical tips on goal setting can help make it easier to set and reach goals:

  1. Specific, realistic goals work best. When it comes to making a change, the people who succeed are those who set realistic, specific goals. "I'm going to recycle all my plastic bottles, soda cans, and magazines" is a much more doable goal than "I'm going to do more for the environment." And that makes it easier to stick with.
  2. It takes time for a change to become an established habit. It will probably take a couple of months before any changes — like getting up half an hour early to exercise — become a routine part of your life. That's because your brain needs time to get used to the idea that this new thing you're doing is part of your regular routine.
  3. Repeating a goal makes it stick. Say your goal out loud each morning to remind yourself of what you want and what you're working for. (Writing it down works too.) Every time you remind yourself of your goal, you're training your brain to make it happen.
  4. Pleasing other people doesn't work. The key to making any change is to find the desire within yourself — you have to do it because you want it, not because a girlfriend, boyfriend, coach, parent, or someone else wants you to. It will be harder to stay on track and motivated if you're doing something out of obligation to another person.
  5. Roadblocks don't mean failure. Slip-ups are actually part of the learning process as you retrain your brain into a new way of thinking. It may take a few tries to reach a goal. But that's OK — it's normal to mess up or give up a few times when trying to make a change. So remember that everyone slips up and don't beat yourself up about it. Just remind yourself to get back on track.

Drugs: What You Should Know


These days, drugs can be found everywhere, and it may seem like everyone's doing them. Lots of people are tempted by the excitement or escape that drugs seem to offer.

But learning the facts about drugs can help you see the risks of chasing this excitement or escape. Here's what you need to know.

The Deal on Substances

Thanks to medical and drug research, there are thousands of drugs that help people. Antibiotics and vaccines have revolutionized the treatment of infections. Medicines can lower blood pressure, treat diabetes, and reduce the body's rejection of new organs. Medicines can cure, slow, or prevent disease, helping us to lead healthier and happier lives. But there are also lots of illegal, harmful drugs that people take to help them feel good or have a good time.

How do drugs work? Drugs are chemicals or substances that change the way our bodies work. When you put them into your body (often by swallowing, inhaling, or injecting them), drugs find their way into your bloodstream and are transported to parts of your body, such as your brain. In the brain, drugs may either intensify or dull your senses, alter your sense of alertness, and sometimes decrease physical pain.

A drug may be helpful or harmful. The effects of drugs can vary depending upon the kind of drug taken, how much is taken, how often it is used, how quickly it gets to the brain, and what other drugs, food, or substances are taken at the same time. Effects can also vary based on the differences in body size, shape, and chemistry.

Although substances can feel good at first, they can ultimately do a lot of harm to the body and brain. Drinking alcohol, smoking tobacco, taking illegal drugs, and sniffing glue can all cause serious damage to the human body. Some drugs severely impair a person's ability to make healthy choices and decisions. Teens who drink, for example, are more likely to get involved in dangerous situations, such as driving under the influence or having unprotected sex.
