440,000 deaths! Wow, that's amazing. How many drugs contain tobacco?


Interesting question. hmmm.....well some people combine marijuana and tobacco and there are many types of tobacco products out there too like clove cigarettes, bidis, and snus. So tobacco can take many forms.

A student recently died from Crystal Meth in our school. How did this occur?


The most likely cause is from an arrythmia (heart rhythm problem) but the actual cause for the student would be determined by the medical examiner in your area. This is really hard on the family and friends of the person who died. Perhaps your school can use this sad event to get people to talk about the dangers of drugs.

According to Wilson Compton, he recently answered a question based on the most common highschol drug abuses... Why is alcohol considered a drug?


Great question! alcohol affects the brain in very similar ways to all the illegal drugs. Alcohol is habit forming and addictive the same way as cocaine, heroin, marijuana can be addictive. We see the same kind of family problems, job trouble, and behavior problems with alcohol as with the illegal drugs. Of course, there are some differences but it's important to realize that alcohol and tobacco are drugs, too! See for more info about alcohol.

-Wilson Compton

After how manyt imes of use did you become adicted?


Good question, but it really is hard to specifically answer this. Addiction really depends on the drug that you are taking, how much you are taking, and it depends on your own individual vulnerability to the specific drug. We also know that some people can be more sensitive to a drug's effects and therefore can be more vulnerable to becoming addicted than others. What we do know is that we can become addicted to all drugs of abuse. To learn more about understanding drug abuse and addiction, please see: Thanks for your interest.

All my friends try and get me to smoke crack with them and snort herion what should i tell them?


You can tell them "No Way!" I think you need new friends! Cocaine is a powerfully addictive drug. Common health effects include heart attacks, respiratory failure, strokes, and seizures. Large amounts can cause bizarre and violent behavior. In rare cases, sudden death can occur on the first use of cocaine or unexpectedly thereafter. Heroin is a very addictive drug as well and use of it is associated with fatal overdoses. For more information, take a look at

All the things on the inhalents' chart with the exapmles and effects does all of that really happen?


This is a very good question. When you look at charts like that they usually list all the effects that have been observed or reported among a large number of users. Whether or not a specific outcome or effect happens to somebody you know depends on a huge number of factors that include the type of inhalants, dose, frequency of use, age, use of other drugs, etc. To learn more about inhalants, please go to:

are drugs fun


Illicit drugs can make you feel better and that's why many people start using them. Initially all drugs of abuse either directly or indirectly increase the activity of the chemical dopamine in the brain's reward centers, which is what makes people feel good. However, with continued drug use, the brain starts to adapt to the good feeling, so more of the drug is needed to achieve that good feeling. This is what causes people to become dependent on the drugs, to feel bad when the drugs are not in their system, and to seek and take the drugs compulsively -- without even thinking about it. Another way drugs change your brain is they affect decision-making, such as being able to judge what is healthy and what is dangerous. The compulsive seeking and using of drugs even in the fact of potentiallly devastating consequences is the essence of addiction. Check out our online publication on the science of addiction to learn more about the way drugs can change your brain. Go to

Are girls more prone to alchohol and drugs or are boys?


Thanks for your question! Girls and boys can have different patterns of drug use, and may be affected by drugs in slightly different ways depending on the drug. For example, boys report more alcohol use and binge drinking than girls, and are more likely to be dependent on alcohol than girls. About the same number of girls and boys smoke cigarettes, although girls sometimes have a harder time quitting than boys once they start. But all teens are at risk of using drugs, and can become addicted if they do - both boys and girls!

are there actually many people who use drugs? i'm very curious because i think its very rare... i dont see any people who uses drugs around me


Congratulations, it is great that you do not see any people around you using drugs. By not using drugs you and your friends not only spare yourself a lot of potential trouble, you set a healthy example for others--and we know that people are less likely to use drugs if the people around them stay away from drugs.Unfortunately not everyone is doing as well as you and your peers. Monitoring the Future is an ongoing study of the behaviors, attitudes, and values of American secondary school students, college students, and young adults. Each year, a total of approximately 50,000 8th, 10th and 12th grade students are surveyed. In 2007,19 percent of 8th graders, 36% of 10th graders and 47% of 12 graders said that they had used an illicit drug at least once. The good news is that teens are taking better care of themselves. Illicit drug use declined by 24% from 2001 to 2007. To see all the results from the latest Monitoring the Future survey, see

Are there any drugs that aren't harmful to the body? if so aren't they only prescription drugs?


Good question! Caffeine may not be harmful to the body--but nearly any drug taken in excess can cause problems--and even caffeine can induce anxiety if you take enough of it. Prescription drugs are only safe for those for whom they are prescribed and if taken as prescribed. If you would like more information check out Thanks for joining us!

Are there any drugs that don't hurt your body and you can't get addicted to?


Thanks for your question - you might be interested to know that all drugs of abuse have some effect on your brain and body. Given continued use, we do know that all drugs can lead to abuse and addiction. There are a number of factors that can affect addiction, including individual differences to vulnerability to drugs. Be smart before you think about taking drugs. But, if you do, the earlier you stop, the more likely you will be to avoid addiction and the harmful brain changes that lead to it.

-Joe Frascella

Are there drug problems in other countries or is America the place that uses the most drugs?


Hi, great question! Drug abuse is a worldwide problem in both developed and developing countries. According to the World Health Organization, there are 76.3 million persons with alcohol use disorders worldwide, and at least 15.3 million persons who have drug use disorders. Injecting drug use has been reported in 136 countries, of which 93 report HIV infection among this population. Here is some more information to learn how the rest of the world is being affected by drug use:

-Marsha Lopez

are there medications to get off major drugs?


Yes, a person addicted to opiates like heroin or prescription pain relievers can be treated with medications, including methadone or buprenorphine, buprenorphine/naloxone, and naltrexone. A person addicted to alcohol can be treated with such medications as Antabuse, naltrexone, acamprosate, and tranquilizers ( for withdrawal). Smokers can use nicotine replacement therapy like patches or gum, or medications like Wellbutrin or Chantix to help them quit. For more information see, an illustrated and easy-to-read booklet on different aspects of addiction, including treatment.

Are you always damaging your body when you're getting high?


It is hard to specifically answer this. There is a lot we still dont know about who becomes addicted and why, and after how much drug exposure. We do know that each person is different, so its a little like playing "Russian Roulette" if you choose to use drugs. But, if you do, the earlier you stop, the more likely you will be to avoid addiction and the harmful brain changes that lead to it.

Can a woman get addicted more faster to a drug than a man?


It depends on the genetics of the person. Some people inherit genes that make them more vulenrable to addiction than others. We are studying whether women overall are more sensitive to addiciotn than men,but the results are not conclusive.

-Nora Volkow

can alcohol effect your really relationship with friends, family, and boyfriend/girlfriends?


It sure can. Relationships can be one of the casualties of drinking. It's hard to maintain a good relationship if you are not really available - you are wasted or hung over or you are hiding what you are doing. Instead of spending energy on friends/boyfriend/girlfriend and family, you spend that energy/time/money on drinking. Alcohol can devastate family relationships, friendships, romantic relationships. The good news is that there is help available, both for people who are drinking (1-800-662-HELP, or ) and for the people in their lives.

can u get adicted to drugs after one try?


Hi there! Not usually, but it can happen. It depends on the drug, on how you take it (smoked, orally, intravenously), how much of it you take, and it also depends on you. Some people are more vulnerable than others. If you have a family history of drug problems--that's a big red flag, but even if you don't you may have other risk factors that make you vulnerable. For more information go to Thanks for your question!

can u overdose of marijuana


I have a complex answer for you here. Using marijuana can produce adverse physical, mental, emotional, and behavioral changes, and it can even be addictive. Chronic or long-term exposure to marijuana smoke, like cigarette smoke, can harm the lungs. The use of marijuana xan impair short-term meory, verbal skills, and judgment and can also distort perception. Data show that students who smoke marijuana regularly get lower grades and are less likely to graduate from high school, compared with their non-smoking peers. In addition, marijuana has been associated with a number of mental conditions, including schizophrenia (psychosis), depression, and anxiety. We don't know yet whether marijuana can cause mental illness, particularly in healthy people who are not otherwise vulnerable to these disorders. There is good new though, since there is evidence that if you quit using marijuana, even after long-term or heavy use, your cognitive abilities (learning and memory) can recover.

-Jan Lipkin

Can using drugs or dinking alcohol daily change your atitude/ personality?


Yes, it depends on the drug and your own personality. Repeated use of some drugs produces depression and anxiety. In some people this can lead to irritability and intolerance for others. Some drugs can produce paranoia that can make people aggressive. Other drugs decrease innhibitions which can make people behave in ways that would embarass them.

-Nora Volkow

can weed affect your social status


Yes, it can--and not for the better. Research clearly demonstrates that marijuana has the potential to cause problems in daily life or make a persons existing problems worse. In one study, heavy marijuana abusers said that they were worse off than nonusers in several important measures of life achievement including physical and mental health, cognitive abilities, social life, and career status.The good news is that according to the 2007 Monitoring the Future surveya national survey of 8th, 10th, and 12th graders--fewer kids have been using marijuana each year since the late 1990s. Between 2000 and 2007, past-year use decreased more than 20 percent in all three grades combined. Nevertheless, marijuana use remains at unacceptably high levels, with more than 40 percent of high school seniors reporting use at least once in their lifetimes.

-Eve Reider

can weed effect the baby and make it have problems forming if you are prego?


Hey there - yes, weed/marijuana can affect the baby 'in utero' (which means during pregnancy). We've got a couple of studies on this - including one that has followed the kids from the prenatal/in utero/pregnancy stage until they were adults. And guess what, yep, these studies have found subtle developmental effects on things like attention and cognition. Tobacco use can also affect the baby. We recommend pregnant women not use alcohol or drugs including tobacco if they are, and ask their doctor for some help if they are having trouble stopping.

-Nicolette Borek

can weed effect you sexual life?


Good question. It can indirectly. When a person is under the influence of marijuana their judgment can be skewed. They might make risky decisions about sex that could put their health at risk.
