Can you tell me what the percentages of middle school teens in the U.S. that are using alcohol or marijuana? Aren't the majority NOT using these substances?

-jojo, Massachusetts

Hi, jojo, great question and you are correct!  The majority of teens are not using alcohol, marijuana, or drugs of any kind.  Between 60 and 70% of 8th graders haven't ever used alcohol, cigarettes, or other drugs, according to the national Monitoring the Future survey. If we're talking about using in the month prior to the survey, that number jumps to 80-90%.  The same study reported 6.5% of 8th graders reported using marijuana and almost 10% had consumed alcohol in the past month.  For more stats, go to www.monitoringthefuture.org

Can your kids get problems if you smoke weed then have a kid?

-con bon , New Jersey

Hey con bon -- Not to get too much into the weeds, but yes!  If mom or dad has used drugs, the kid may be more vulnerable. BUT.....while genes play a big role, they are only part of the picture. Other factors, like having friends who don't use drugs, or being involved in sports and other recreational activities, also affect your risk of trying drugs and of becoming addicted. Researchers are trying to find the genes that make you vulnerable or resistant to addiction, in order to find ways to improve treatment and prevention approaches.  Want more information on genes, addiction, and teens?

cheapest drug? most expensive drug?

-tmoorf6930, Michigan

Hey there tmoorf6930. Great question, but it's a tough one to answer. It depends on a lot of different variables like, what country are we talking about? how is the drug made? how far does the drug need to travel to get to a user? what are the local drug laws? The Canadian Website O.Canada has rounded up data from the United Nations, the White House, and the Substance Abuse and Mental Health Services Administration to create "http://wpmedia.o.canada.com/2014/10/drugprices_ig.jpg" to give you some answers.

Christian Sims-Calera High School: How many drinks does it take for you to get alcohol poisoning?

-gniven, Alabama

Good question. That's something that would depend on how old the person is, their size, whether they are used to drinking alcohol, and other factors. It's important to recognize the signs of alcohol poisoning. Critical signs of alcohol poisoning include:

  • Mental confusion
  • Stupor
  • Coma
  • Vomiting
  • Seizures
  • Slow or irregular breathing
  • Hypothermia (low temperature)
  • Bluish skin color
  • Paleness

If you think someone you know may be experiencing alcohol poisoning, make sure to get help immediately. You can call 911.

could a baby in the womb get high by their mother smoking

-NikeriaT125, Georgia

Hi NikeriaT125,
Every drug a pregnant woman takes also reaches her baby. The ways in which the baby can be affected depends on the drug the mother takes, how much she uses, and when in pregnancy she uses. But the good news is that the sooner a pregnant woman stops using drugs, the better the results for her baby.

Do you think fast food is equivalent in harmfullness to drugs?

-fdang, Texas

they are different. Fast foods are not good for you and can lead to compuslive overeating and obesity. Drugs of abuse, on the other hand, affect your brain and cannot only make you addicted but can affect your intelligence and mood.

-Nora Volkow

Do you think marijuana has any medical benefits?

-\.=., Massachusetts

This is a Frequently Asked Question: Why is weed illegal if it is a medicine? 
Marijuana for medical use has been in the news a lot lately. The marijuana plant has not been approved by the FDA for the treatment of any medical condition. There is early research suggesting that some of the active ingredients in marijuana, like THC and cannabidiol (CBD), may potentially help treat things like epilepsy, cancer, obesity, or addiction. Scientists are studying these ingredients to try to develop new medications.   A pill form of THC (an active ingredient in marijuana) is already available for certain conditions, such as nausea associated with cancer chemotherapy and weight loss in patients with AIDS.  However, smoked marijuana is unlikely to be an ideal medication because of its negative health effects, including the risk of addiction and the damage that smoking can do to the lungs.

-Maureen Boyle

Do you think people would continue to use cigarettes if nicotine was removed from them?

-FSCAA, Delaware

Excellent question FSCAA!! Best one yet. We think that people would not use cigarettes as much if nicotine was removed. A recent study shows that cutting the amount of nicotine in cigarettes leads to a reduction in the amount of cigarettes smoked per day, decreased nicotine dependence, and reduced cravings. Check out the summary here:"http://www.drugabuse.gov/news-events/news-releases/2015/10/reducing-nico...".There are a lot of scientists hard at work to help answer this question!!

do steroids make your muscles bigger but more fragile

-mosesc, Texas

Steroids don't make you big and strong by themselves--you have to work at it with exercise.  And if you do the work, you are getting bigger and stronger by yourself!  Anabolic steroids do help build muscles, but only in specific areas on the body with "androgen receptors," in places like the neck and shoulders, places that are visible to others.  But no one has actually shown that they can make you stronger or increase your endurance.  And steroids can be dangerous.  In males, they can reduce the size of testicles, cause baldness and cause development of breasts.  In females, they can cause growth of facial hair, baldness similar to men and a deepened voice.  In adolescents, they may prevent you from reaching your full height.  I don't understand what you mean by making your muscles more fragile, so I can't answer that.  There is more information at http://www.drugabuse.gov/publications/drugfacts/anabolic-steroids

Do the consequences of legalizing marijuana outweigh the economic benefits?

-student22, Michigan

Hi student22,
Legalization of marijuana for adult recreational use and for medicinal purposes is currently the subject of much public debate. For the last few years, the Department of Justice has said that it is not going to prioritize enforcement of federal marijuana laws when state laws allow for possession of small amounts of marijuana. They are giving states the flexibility to test new policies for both ‘medical’ and recreational use of marijuana. Public health experts are worried that these changing policies could lead to more use among teens. Regular marijuana use as a teen may harm the developing brain – making learning and memory worse – and can impair the ability to drive safely (especially when combined with alcohol). There is a lot of reserach going on right now to better understand both the economic and public health consequences of marijuana legalization. 

-Maureen Boyle

Do the effects of steroids wear off once you stop, or do they stay permanently?

-Sagu, Texas

Hi Sagu,
Steroids are hormones that your body produces in very small quantities when you need them.  But people who abuse them take 100-1000 times more than what you need, and that leads to the changes that occur.  Some effects are temporary, others are not.  For example, if you are a female using anabolic androgens to give you an edge in sports, these hormones may cause your voice to deepen, just like a male's, and this is permanent.  Steroids can also stop growth in the long bones that contribute to your final height, so teens of both sexes risk becoming shorter than expected.  These can also promote aggressive behaviors in both sexes, but this effect is usually temporary.  And, some report a feeling of depression after withdrawal from long-term use;  this is also usually temporary.  NIDA has more information on steroids at http://teens.drugabuse.gov/drug-facts

-Nancy Pilotte

do the effects of the alcohol you consume depend on your gender?

-bryanaa, New Mexico

Some of them do, yes. Females tend to weigh less than males and so reach higher blood alcohol levels after each drink. Females appear to be more likely to experience blackouts and memory deficits after drinking than males. Over time, females are more likely to develop liver disease, brain impairments and cancer than males.

-sms, New Jersey

We study humans, rats, mice, monkeys, voles, birds, worms, bees and flies, to name a few. The human brain is the most advanced, but we see similar effects of drugs across animal species.  

-Joni Rutter

Do you consider vape/hookah to be harmful drugs?

-KLW9149, Michigan

You bet! The aerosol, also called vapor,that e-cigs and vape pens produce are chemicals such as propylene glycol, glycerin, nicotine, THC, chemical flavorings, and others. Surveys show that many teens don’t even know what chemicals are in their e-cig device. One thing we worry about with e-cigarettes is that they may lead to nicotine addiction and this might cause some people to start using regular cigarettes, which can cause cancer. Check out these resources on e-cigs to learn more – http://teens.drugabuse.gov/drug-facts/tobacco-nicotine-e-cigarettes. You may think that using a hookah (waterpipe) is less harmful than smoking cigarettes, but it still delivers the addictive drug nicotine and is at least as toxic as cigarette smoking. In fact, research shows that hookah smokers inhale 100 to 200 times the volume of smoke in a 1-hour hookah session than they would from a single cigarette.

-Joni Rutter

Do you feel relaxed when you drink?

-AyenaK, Texas

Some people do. But it's important to understand why that happens. There are parts of our brain that tell us to feel stressed or worried that something might happen. Alcohol turns down the activity in these areas, which creates the illusion that the stress is gone - and that helps us feel more relaxed. Unfortunately, as soon as the alcohol wears off, the feelings of stress come back - and can be even worse than before. While people might feel a little less stressed after drinking some alcohol, they generally feel extra stressed when it wears off.

Do you get addicted to steroids ?

-Nallely M, New Mexico

Hello Nallely M.  There is increasing evidence that you can become addicted to steroids.  Steroids are very powerful and affect your brain, your liver, your reproductive organs, and increase the risk of cancer (even if you do not become addicted).  There is more information here: https://teens.drugabuse.gov/drug-facts/anabolic-steroids.  Great question.

-Roger Little

Do you get withdrawl if you stop using cocaine for a while?

-mbanks, Texas

Hello mbanks, the short answer is that if you are addicted yes you can.  People who are addicted to cocaine will go to great lengths to get it because they crave it so much and not having it makes them feel so unwell.  To the point of stealing money which can cause them to lose their jobs, their marriages, and families.  A person can feel jittery or anxious and it can cause lasting damage to your heart and cardiovascular system. There is more information here.

Couldn't legalizing and taxing marijuana generate significant revenue?

do a lot of teens drink when they are still in high school

-Abigaila, New Mexico

By age 15, about 35 percent of teens have had at least 1 drink.
By age 18, about 65 percent of teens have had at least 1 drink.
In 2014, 8.7 million young people ages 12–20 reported that they drank alcohol beyond "just a few sips" in the past month.

Another way to think about these numbers is: Only about 1 out of 10 kids ages 12 to 17 drank alcohol in the past month. So MOST – about 9 out of 10 – did not drink alcohol. This information comes from the 2014 National Survey on Drug Use and Health (NSDUH, 2014)

do people drink alcohol for enjoyment

-ennisisd, Texas

People drink alcohol for a lot of different reasons. Some people may get messages from movies, TV, and our general culture that drinking can make you feel "cool." Others may feel that they can escape problems in their life by drinking. But they cannot - drinking only makes any problems you already have much worse. And there's nothing cool about throwing up in a garbage can or wrecking a car.
