can thc cartridges be laced with other drugs/chemicals other than just weed?

-.., Illinois

Good question! The aerosol, also called vapor, that is produced by vaping devices is really made of the specific chemicals in the liquid, such as propylene glycol, glycerin, nicotine, THC, chemical flavorings, and others. Unfortunately, it's not always possible to tell what chemicals are in the vapor produced by a particular device/liquid and surveys show that many teens don't know what chemicals are in their vaping device. Because vaping devices are so new, we still don't know what effects these chemicals have on health. Best to stay away from them!

Can people overdose on weed?

-CM, Illinois

Hi CM,

This is a great question!
An overdose occurs when a person uses enough of the drug to produce life-threatening symptoms or death. There are no reports of teens or adults dying from marijuana alone. However, some people who use marijuana can feel some very uncomfortable side effects, especially when using marijuana products with high THC levels. People have reported symptoms such as anxiety and paranoia, and in rare cases, an extreme psychotic reaction (which can include delusions and hallucinations) that can lead them to seek treatment in an emergency room.

I hope this helps!

can people stop using drugs

-Javares-FVSU4h, Georgia

Hi, this is a great question! Yes, it is definitely possible to stop drugs. Think of the people who quit smoking. That does not mean it is easy. Support from friends and family and getting the right treatment are crucial to stopping drugs. The good news also is that as soon as people quit, their brain and body can start to heal. See these resources about drug treatment on NIDA's website: Treatment Approaches for Drug Addiction: https://www.drugabuse.gov/publications/drugfacts/treatment-approaches-drug-addiction See NIDA's Step-by-Step Guides to determine if you or a loved one has a problem with drugs: www.drugabuse.gov/related-topics/treatment

Can smocking cigarettes be used as medication?

-SM, Illinois

That's an interesting question! People sometimes smoke to relieve stress, but studies suggest smoking may actually be linked to increased chances of having an anxiety disorder or depression, especially in teenagers. Also, smoking is seen to cause multiple types of cancer, including lung cancer. You can find more information on smoking's effects on the brain and body here: https://teens.drugabuse.gov/drug-facts/tobacco-nicotine-e-cigarettes.

Can smoking at a young age affect your future health?

-noodles, Illinois

Hi noodles. Yes, it can! There is no safe level of exposure to tobacco smoke. Smoking has multiple harmful effects, such as causing lung or heart disease. The longer someone smokes, the more likely they will experience the harmful effects. However, when a person quits, their body slowly starts to recover immediately. If someone doesn't smoke, they shouldn't start. But if they do smoke, it is always worth their health to stop.

can smoking weed give you erectile dysfunction?

-LG, Montana

HI Igillmore - No, but smoking weed will make you dumb. Marijuana has so many effects on your body. The brain might be the most affected. Research has shown that marijuana affects learning and memory, which can affect your schoolwork; coordination and judgment, which affects your ability to drive and play sports. It can also be addictive. https://teens.drugabuse.gov/blog/post/10-things-you-can-learn-about-marijuana-drugs-health-blog. Smoking marijuana appears to affect your lungs and respiration. There are receptors for THC, the addictive chemical in marijuana, throughout the body. These receptors regulate pain or immune responses, and thus, smoking marijuana may change your normal pain and inflammatory responses.

Can u drink at the age of 18 because, a lot of countries allow drinking at the age of 18.

-Big Chungus, Illinois

Hello Big Chungus!
In the US, the legal age for drinking is 21. Our brains continue to develop from our childhood to young adulthood. The harmful effects of alcohol on the brains of kids and teenagers (including 18 year olds) are well known. In adults and teens, binge drinking - drinking too much and too quickly - can cause alcohol to accumulate in your body and increase the risk of damage to the brain, liver and other organs. Check out our website on Underage Drinking for more information.
Hope this helps!

can u od on the nic

-kermit the frog, Illinois

While it is harder to accidently overdose with nicotine than other drugs like heroin, it is possible. Nicotine is actually very poisonous and can result in death if consumed in very high amounts. Children are most at risk of nicotine poisoning through eating cigarettes or nicotine-containing products, or drinking or touching liquid nicotine. The CDC says 50 to 60 milligrams of nicotine is a deadly dose for an adult who weighs about 150 pounds. But some research suggests a lethal amount may be a lot higher.

can u overdoes on weed

-duude, Illinois

Hi duude, Yes-- you can overdose on weed. You could have a terrible experience and end up in the emergency room. But you will probably not die from the overdose. When people say "you can't overdose on weed," they really mean you can't FATALLY overdose. Great question!

-Roger Little

can u overdose on melatonin

-guinea pig!, Oregon

Hello,

An overdose occurs when a person uses enough of the drug to produce life-threatening symptoms or death. Melatonin appears to be safe when used short-term, but the lack of long-term studies means we don't know if it's safe for extended use. Also, taking more than the recommended or prescribed dose should be avoided and always discussed with your doctor.

Can using some drugs lead to mental conditions like ADHD?

-fer507452, Illinois

For the most part, illicit drugs do not usually cause mental illnesses. Some drugs can cause attention problems, but usually just when you are taking them. That said, exposure to drugs, especially early in life, can have long-term consequences on the development of the brain, raising your risk for ADHD and other brain disorders.

-Joshua Gordon

can using too many drugs or consume too much alcohol create a mental disorder?

-AP, California

Yes--alcohol and drugs are often linked with mental disorders, although sometimes its hard to know which came first. And Also, if the addiction is treated sometimes the mental disorder also improves. Alcohol is linked to depression, marijuana--to psychosis, especially in someone who as a genetic vulnerability.

Can vaping affect the health of your future offspring?

-Brendan, Illinois

Thanks for the question, Brendan. Because vape products are so new, there's still so much we don't know about vaping, particularly how it affects health in the long-term. We do know that every drug a pregnant woman takes also reaches her developing baby. This includes nicotine which is in many vape products. The CDC cautions that e-cigarettes and other products containing nicotine are not safe for use during pregnancy. Nicotine can damage a developing baby's brain and lungs and the flavorings in e-cigarettes may be harmful to the developing offspring as well.

Can Vaping Cause Cancer or other disease in the body?

-EG, Illinois

B: Hi there - this is a great question - and your friend is lucky that you are concerned. The best thing you can start with is to listen to him. Sometimes people don't even realize they are acting differently, and just saying something like "you seem like you have been kind of sad lately" might help give your friend permission to talk about it. You can then encourage him - and offer to help him connect with a trusted adult so that he can begin to get help. Here is some information that may be helpful: https://www.nimh.nih.gov/health/publications/teen-depression/index.shtml...

can vaping cause lung cancer? if so what in it causes it versus smoking cigarettes?

-big chungus, Illinois

Hi, big chungus - Many vaping liquids contain nicotine, which is one of the most addictive substances. Vaping may cause some people to start using regular cigarettes, which can then cause lung cancer. So, while vaping may not expose you to all of the same chemicals that cigarettes do, it's still not safe. In addition, the contents in vaping devices are not regulated, so it's impossible for a user to know what he or she is vaping. The liquid could contain a combination of propylene glycol, glycerin, chemical flavorings, and/or other chemicals in addition to nicotine. We are still learning about the long-term effects of vaping. For more information, see: Bottom line about e-cigarettes (fact sheet): https://www.cdc.gov/tobacco/basic_information/e-cigarettes/pdfs/Electron...

can vaping effect a pregnant woman

-vic, Illinois

Hi vic,

I'm guessing that you are wondering if vaping in pregnancy can harm the baby. We don't have research on that yet in humans (the link above talks about a study in mice), but we have concern that could happen because we do know that smoking during pregnency can cause harm to baby and to the develoing child, and most vaping products contain nicotine and would thus pose similar risks. You can read about it here: https://www.drugabuse.gov/publications/research-reports/tobacco-nicotine-e-cigarettes/what-are-risks-smoking-during-pregnancy. We also know that the sooner smoking stops in pregnancy, the better for baby. It's never too late to quit!

-Cora Lee Wetherington

Can vaping every day cause the same damage as chronic smoking?

-tuRrbOtAstic, Illinois

Thank you for joining us, tuRrbOtAstic! While we are still learning about the long-term effects of vaping, we know that regular vaping increases that person's exposure to nicotine. Nicotine is addictive, so when someone becomes addicted to nicotine, they will seek it out even if it interferes with their normal activities. Vaping, particularly in kids, can lead to the use of regular tobacco products, like cigarettes, which are very harmful. Exposure to drugs, including nicotine, can affect brain development and contribute to a range of problems later in life. While vaping may not expose you to all of the same chemicals that cigarettes do, it's still not safe. However, if someone is vaping to quit using cigarettes, this can reduce the number of toxic chemicals they are exposed to. The goal should be to quit use of all tobacco products! For more information, see: https://teens.drugabuse.gov/drug-facts/tobacco-nicotine-e-cigarettes.

can vaping harm your brain

-mschmaus11, Montana

Any drug that you may vape is going to affect your brain the same as smoking or other ways of consuming drugs. Vaping is promoted as being less harmful because the material is heated to the point of evaporation, which is lower than the temperature for combustion, which produces a number of harmful chemicals. However, many vape pens use solvents like propylene glycol, which is used in anti-freeze for cars. The long-term effects of inhaling propylene glycol are not established. Whether you are vaping or smoking, you are intending to ingest a drug. The most common drugs that are vaped are nicotine and marijuana. Vaping may be marginally better than smoking combustible materials, but you are still liable for the addictive and other harmful effects of the drugs you are vaping.

Can weed help anxiety?

-elastigirl, Illinois

The short answer is no. There is no good evidence that marijuana helps with mental illnesses. In fact, teen use of marijuana has been associated with an increased risk of some psychiatric disorders, such as schizophrenia. If you've already tried other treatments for anxiety and you feel like you're not getting better, then talk to a trusted adult and let them know that you're struggling. The good news is that there are effective treatments available for anxiety (many of them don't involve any medication!). If you have questions about substance abuse or mental health treatment, call 1-800-662-HELP, 24/7. Or you can go to www.findtreatment.samhsa.gov/ to find information about treatment centers in your area.

Can doing drugs stunt your growth?

-Noah H, New Jersey

Hi Noah
Yes, anabolic steroids are well known for this effect. High hormone levels coming from steroids signal to the body to stop bone growth too early. AS use in teens can also stunt height if use happens before the growth spurt
thanks for a great question
