'Bath salts' have just been banned for a year in the United States. What can these chemicals do to the human body and brain?

-shannonl, Ohio

Good question.Unfortunately people are ingesting bath salts searching for a high, but many are finding serious consequences! Bath salts contain chemicals similar to ectascy, amphetamine and cocaine, which are associated with bad side effects like dangerously elevated blood pressure and heart rates, there have been reports of people becoming so agitated that their muscles started to break down, releasing chemicals that led to kidney failure. So, while it seems like bath salts woudn't pose any harm, used in the wrong way, it can be seriously dangerous stuff!

1. What is the percentage of people who overdose on drugs per month? 2. Can prescription drugs cause hallucinations? 3. What percentage of teens use prescription drugs?

-koster, Iowa

Over a thousand people die each month in the US from prescrition pain killer overdoses. Halucinations are rare from prescription opioids. NIDA puts out a publication that answers a lot of questions about teen drug use. Check it out! http://monitoringthefuture.org/pubs/monographs/mtf-overview2010.pdf

a lot of people need mental help right?

-cnunez, Texas

hi cnunez: It's true: mental disorders are pretty common, and over their lifetime, many people struggle with these problems and need help. In fact, mental illnesses are not as rare of some people think. About 20% of youth will have at least one type of mental illness in their lifetime. But the good news is that we have good treatments for the mental health problems that affect children, teens, and adults. Depending on the person and the problem, these treatments can include specific talk therapies (psychotherapies), medications, or a combination of treatments. So when someone is struggling, it's important for them to talk to a professional as early as possible to get help. Mental illnesses are real and can be treated. They are not often something a person can just snap out of. Some people do not get help because they are embarrassed or afraid to. However, getting help for mental issues is really no different than seeking help for a medical condition like diabetes. If you or someone you know needs help go to http://www.nimh.nih.gov/health/topics/getting-help-locate-services/index.shtml for information on who to talk to and how to find help in your area.

A question was asked 'Is

-ImNotAPanda, Pennsylvania

Yes, for teenagers, even moderate consumption of alcohol appears to be harmful. Research shows that having alcohol during the teen years increases the odds of becoming an alcoholic at some point in life. This happens even if you drink at home with your parents. In fact, research in Europe, the US and Australia indicates that teens who are allowed to drink at home even while being supervised by parents are more likely to binge drink (drink enough over about 2 hours to get very drunk) outside of the home. It isn't clear how much alcohol is needed to directly damage the brain during the teen years, but it is probably more than the amount of alcohol considered to be moderate for adults (no more than 1 drink per day for women or 2 for men). Even if the brain is spared from being damaged by moderate consumption during the teen years, the risk of becoming an alcoholic is increased significantly

About how long does it take to quit and recover from using drugs?

-cthompson, Pennsylvania

It depends on what they are addicted to. If marijuana users quit, it's often in their twenties after starting in their teens (so 10+ years to get around to quitting). Older age and marriage are predictive of quitting. But plenty of people remain addicted or frequent users of marijuana into older adulthood. Very few seek formal treatment. Stimulant and heroin users quit later and often heroin users remain on methadone (a treatment medication) or go back to using heroin. It can be a lifelong battle. Technically, it takes only one day to quit cold turkey, but fixing all the damage to relationships, employment history, and educational history can take a very long time and in some cases be insurmountable. Some people remain in AA (Alcoholics Anonymous) or NA (Narcotics Anonymous) type groups their entire lives or cycle through patterns of recovery and relapse. Most people who quit drugs do it without formal treatment but these people usually have less severe and shorter use histories.

about how many childeren use alchol or drugs?????

-harry.h, Texas

The Monitoring the Future Study is a survey conducted by the University of Michigan every year where they ask 8th, 10th, and 12th graders about their drug use behavior and attitudes. In 2010, around 20% of 8th graders, 32% of 10th graders, and 39% of high school seniors reported they had used some type of drug in the past year (includes any use of marijuana, inhalants, LSD, other hallucinogens, crack, other cocaine, heroin, narcotics other than heroin, amphetamines, sedatives (barbiturates), or tranquilizers not under a doctor’s orders). In the same study 29% of 8th graders, 52% of 10th graders, and 65% of high school seniors reported having used alcohol at some point in the past year and about 12% of 8th, 30% of 10th, and 44% of 12th graders reported they had been drunk in the past year.

About how many years does it take for you to stop taking a drug?

-jvu, Texas

Hi, jvu. Many people struggle with drug addiction, but with proper treatment, quitting is an achievable goal. How long it takes will depend on a number of factors, including what drugs someone is taking, how much they're taking, and for how long. See http://www.drugabuse.gov/scienceofaddiction/index.html for more info.

-ZaCh!, Ohio

Hey ZaCH! Not only may you experience loss of smell, but also a chronically runny nose, nosebleeds, hoarseness, and problems swallowing. Also, chronic users of cocaine can become malnourished due to the drug's ability to decrease appetite. But I wouldn't ingest cocaine -- period. It could cause severe bowel gangrene due to a reduction in the flow of blood to the intestines. That's nasty! If someone were to inject it, they could experience severe allergic reactions, increased risk for contracting HIV, hepatitis and other blood-borne diseases. For more information on cocaine, see:

Aisha kenmore do the drug laws differ from state to state and if so, why?

-pdoug, Virginia

Hello - and thanks for your question. I Don't know that I can really answer the question about 'why' the laws regarding illicit drugs differ from state to state. What I do know is that the legal consequences for posession of drugs differs by type of drug, amount, and where you are when you get caught. Here are the Federal penalities for cocaine and for marijuana http://www.justice.gov/dea/druginfo/ftp3.shtml. My advice - don't possess or use drugs and then you don't need to worry about legalities.

-Redonna Chandler

Alcohol kills more people than any other drug...why is it legal?

-DjChop, Pennsylvania

That's a complicated question. In the early 20th century, alcohol was banned all together. While that strategy (called 'Prohibition') did save some lives, it wasn't considered a success in general and alcohol was made legal again. In addition, many people use alcohol responsibly and enjoy it for a wide range of purposes, including celebrations and religious ceremonies. The government can regulate - but not prevent - people from using alcohol in those ways. The exception is the legal drinking age of 21. Making it illegal for people under 21 to drink alcohol has proven to be important for reducing alcohol-related deaths, including from traffic crashes, in young people.

Are there any countries that allow weed? And why?

-Que?, New York

Hello Skaneateles High School! Thanks for the thoughtful question....The legality of cannabis (aka, weed) has been the subject of debate for many decades and in different societies. Different societies decide to control drugs through varied ways (how is supplied/cultivated, how it can be possessed or not, how it can be sold, etc.). Some countries that have decided to decriminalize cannabis--an example is the Netherlands. However, in the majority of countries cannabis remains illegal.

Are there any physical or mental effects that

-briannaf, Pennsylvania

There sure are! Some people die after a single use of inhalants, because the effects are so rapid and there is no antidote other than oxygen. The lungs rapidly absorb inhaled chemicals into the bloodstream, quickly spreading them throughout the body, including the brain. Within minutes of inhalation, users can feel a 'buzz' or 'high.' The effects are similar to those produced by
alcoholand may include slurred speech, lack of coordination, euphoria, and dizziness. Inhalant users may also experience lightheadedness, hallucinations, and delusions. The high usually lasts only a few minutes. But with repeated inhalations, many users feel less inhibited and less in control. Some may feel drowsy for several hours and experience a lingering headache. The most important effects occur in your brain. Inhalants often contain more than one chemical. Some chemicals leave the body quickly, but others can remain for a long time, because they stick to fatty tissues in the brain and central nervous system. One of these fatty tissues is myelin, a protective cover that surrounds many of the body's nerve fibers (axons). Myelin helps nerve fibers carry their electric messages to and from the brain. Damage to myelin can slow down communication between nerve fibers. Long-term inhalant use can break down myelin. When this happens, nerve cells are not able to transmit messages as efficiently, which can result in muscle spasms and tremors or even permanent difficulty with basic actions like walking, bending, and talking. These effects are similar to what happens to patients with multiple sclerosis--a disease that also affects myelin. Check out our teen site at

Hi, jeffreyk, that's a complicated question to answer. If by social groups you mean certain ethnic or gender groups you can find out all sorts of information from the University of Michigan's annual Monitoring the Future Study (look at Appendix D), which has specific drug information for 8th, 10th, and 12th graders broken down by gender, race/ethnicity, and parental education among others. If you mean social groups like boy scouts or kickball leagues, sorry I can't help you.

are there natural highs?

-adison_s, Pennsylvania

Absolutely, and that's why it is so silly to seek artifical ones that can and do harm your brain and overall health.The active ingredient in any basic receipe for a natural high is this (are you ready?): find out what you are really passionate about (whatever it is, except drugs, of course), nurture that passion and then follow it to wherever it takes you. It works every time, and you will never regret it.

are there ways to stop using drugs or quit?

-bobbymcwire, California

Yes, if you know someone who is addicted to drugs, you should try to convince him or her to get professional help. There are many successful treatments and ways that can help people quit using drugs. Some people just decide to quit 'cold turkey' but this can be very difficult for some. We know that drug treatment does work and helps many people with this difficult problem.For more information, and for help, see:http://www.findtreatment.samhsa.gov/ or 1-800-662-HELP, where you can find private and confidential help 24/7.

Are they any negative effects of drinking moderately?

-avincent, Kentucky

For adults, one (for females) or up to two (for males) servings of alcohol can help decrease the chances of developing heart disease. However, any more than that increases the risk of developing a host of problems, including liver and pancreas diseases, weakened immune system, and certain kinds of cancers.There are no known benefits of alcohol for teenagers, only negative effects. Starting to drink under the age of 21 is associated with an increased risk of developing alcoholism, getting injured in various ways and developing chronic diseases later in life.For more information on how alcohol can affect your health, check out: http://pubs.niaaa.nih.gov/publications/Hangovers/beyondHangovers.htm

are you more likely to do drugs if you go to public school or are home schooled but do a lot of outside activities?

-isheahan, New Hampshire

This is a little complicated. I don't think that we have research to answer this question one way or the other. You could speculate that a person in a regular school setting may be exposed to more opportunities for getting pressured by peers to use drugs or to have access to drugs than a person in a home school setting where a parent is present throughout the day. But there are a lot of adults monitoring what goes on during the school day and parents are often monitoring after school so it could go either way.

-Belinda Sims

are you most likely to get a disease(cancer and other things) if you start to drink at a young age , lets say 13 or 14?

-acastro, Texas

That's a tough one and we really don't know the answer yet. However, we do know that heavy drinking during the adult years increases the chances of getting cancers of various types, particularly for women, and that starting to drink at a young age, like 13 or 14, is associated with a much higher risk of drinking heavily during the adult years. So, if you look at it this way, getting started young could indirectly increase your odds of developing cancer at some point in life.

As a health teacher. What things do you feel are the most important to address with the middle school aged students to help them learn to make informed decisions about not using drugs?

-rbartlett, New Hampshire

Hello. Thanks for this very good question. It is important to make sure that youth receive information that is developmentally appropriate. It is important for youth to know that drug use is not the norm (everyone is NOT doing it). It is important for youth to know the effects of drugs on the brain and body and how drugs effect their decisions and behaviors. It is important for youth to acquire skills to be able to make good healthy decisions about drug use and other risk behaviors (e.g., communication, decision making and drug refusal skills). Following are some key principles for prevention programs in schools: Programs should focus on children’s social and academic skills, including enhancing peer relationships, self-control, coping, and drug-refusal skills. If possible, school-based prevention programs should be integrated into the school’s academic program, because school failure is strongly associated with drug abuse. Integrated programs strengthen students’ bonding to school and reduce their likelihood of dropping out. Other types of interventions include school-wide programs that affect the school environment as a whole. All of these activities can serve to strengthen protective factors against drug abuse. (See examples of school-based programs in Examples of Research-Based Drug Abuse Prevention Programs.)For information on priniciples of prevention in Drug Abuse Prevention Programs, see: http://www.drugabuse.gov/prevention/applying.html. In addition, a fun curriculum for teachers to use with middle school students can be found here: http://www.drugabuse.gov/brain-power.

as some people abuse prescription drugs, is there a limit of how much prescription drugs you can get by prescription?

-clorenzi, Illinois

For some prescription medications, there are limits on how many a physician may prescribe. For the most controlled medications, the limit is generally enough to last a patient 30 days. But for some medications, there is no legal limit on the number, and physicians may prescribe a 90 day supply (or even longer).

-Wilson Compton

At what age do people become vulnerable to become addictive to drugs?

-acahill, Illinois

Addiction can begin at any age and the earlier someone starts using drugs, the more likely they are to become addicted. Most addiction starts during teen years and recent research has taught us a lot about brain development during adolescence. This is a major time for brain growth and change and drug use may be particularly risky for those who start early.

-Wilson Compton

At what age do the students get influenced to take drugs and what motivates them to do so?

-vaidehi, Georgia

Hello! Individuals who use drugs often have their first use of drugs (onset) in adolescence. The earlier a person begins to use alcohol, tobacco or other drugs the more likely they are to progress to abuse and addiction later on. There are a number of factors that may increase the chances that a young person will use drugs. We call these risk factors. Risk factors may come from one or more sources, including social, environmental, or biological factors, and often more than one risk factor will be present. Just because someone has a risk factor it does not mean that they will use drugs. Youth also have many protective factors in their lives--things that reduce the likelihood of using drugs that could also be social (e.g., positive peer relationships), environmental (e.g., caring and supportive family), or biological (e.g., good self-control). But using drugs can have a lot of negative consequences including losing friends, not doing well in school, getting in trouble with the law, and other problems, too.
