Does vaping cause Erectile Disfunction?

-E, Illinois

Hi E -,
What an interesting question. Unfortunately there is not evidence currently if vaping causes erectile dysfunction. However, smoking cigarettes can damage DNA in men's sperm. There are currently no e-liquids approved to treat erectile dysfunction. For more information about e-liquids and vaping visit https://www.fda.gov/TobaccoProducts/default.htm.

Does vaping get you a better chance to start smoking or doing any other drugs?

-Patrick Star, Illinois

Hi PS - There are scientific studies showing that teens who vape are more open to trying cigarettes. We are still studying whether vapers are more likely to become smokers, but even the increased openness to smoking is concerning. Smoking by teens has been falling every year for the past decade, and that is an important trend that needs to continue. Check out the infographic about vaping from the 2018 teen drug use survey of 8th, 10th and 12th graders:https://www.drugabuse.gov/related-topics/trends-statistics/infographics/...

-Kevin Walton

Does vaping have the same effect on you as marijuana?

-benn, Illinois

Good question, benn! Not necessarily. Vaping solutions contain a variety of chemicals that may include some of the chemicals found in the marijuana plant. Because most people who vape do not include those chemicals, they are being exposed to different substances that would not be expected to produce the same physiological effects.

-Michele Rankin

Does vaping liquids without nicotne harm you?

-elrabidd,

Hi elrabbid, great question. There are a lot of chemicals in the aerosol, or vapor, that comes out of an e-cig. This includes propylene glycol, glycerol, and flavor chemicals. Some of these chemicals are known to be harmful to the lungs, and most have not been shown to be safe for inhaling. Unless someone is trying to stop smoking, people should not start using them.

does weed have effects on the body such as health problems?

-TY, New Mexico

Marijuana can produce a number of health problems. The active ingredient in marijuana, THC, produces adverse effects on the heart, brain and other organs. THC causes increased heart rate and palpitations (i.e., irregular heart beats), which could contribute to serious heart dysfunction. THC leads to impaired thinking and decision making, which could contribute to loss of behavioral control. Long term use of marijuana is associated with an increased risk for psychotic disorders such as schizophrenia, a devastatng brain disease. In short, the risks posed by marijuana are substantial.

-Michael Baumann

does weed relax the body?

-TY, New Mexico

Great question. The active ingredient in marijuana, THC, can produce different effects on the body, depending upon the dose and each individuals' response. In general, THC increases heart rate and can cause palpitations (i.e., irregular heartbeats). Marijuana can produce anxiety, panic attacks and hallucinations. So, contrary to popular belief, marijuana does not relax the body.

-Michael Baumann

Does wine really help your heart, or does it harm your body?

-4176, Illinois

The latest research suggests that small amounts of alcohol, whether from wine or beer or spirits, could make it less likely someone has a heart attack. But it can increase the chance of cancer, injuries, and other bad outcomes. So it looks like it's not worth it to drink alcohol for health.

-George Koob

Does your sexual performance decrease if you do hard drugs

-AMLOver,

Yup- long term use of heroin or cocaine is associated with diminished sexual desire and performance.

-Suzanne Lim

Doesn't LSD have positive affects?

-drugsalcohol, Illinois

Hi drugsalcohol,
Good question
There are quite a few reputable researchers that believe so, and there has been sort of a renaissance in the past decade or so in the area of hallucinogenic research in general and LSD and psilocybin in particular. It will take more time to have a clearer picture of the potential therapeutic and spiritual benefits of these drugs, but I think the scientific community is slowly moving in that direction. Stay tuned.

-Steve Grant

Don't psycadelics have some possible positive affects?

-drugsalcohol, Illinois

Thanks for the question. There are some clinical research studies going on that are studying the possible uses of some drugs like MDMA in some limited circumstances. It's important to keep in mind that studies like this are done with a lot of supervision and in very controlled and safe environments. Psychedelics are mostly used for recreational purposes at relatively high doses; doing this can have a lot of unpredictable effects.

-Roger Little

Dr Dave, what drugs are most addictive

-Chungus, Illinois

All drugs of abuse are addictive, and its hard to say which is the most addictive. It depends on a lot of things. For example, people have a real hard time quitting smoking. But a lot of smokers smoke all day long, and that is likely part of why they are hard to quit. For more info, check out the NIDA for teens website on the different kinds of drugs and their affects on the body: https://teens.drugabuse.gov/drug-facts.

-Steve Grant

Drinking while pregnant can cause fetal alcohol syndrome, and doing drugs while pregnant can lead to an addiction for the baby. What are the effects of smoking marijuana while pregnant? Also, are there any addictive properties in marijuana?

-I am Spartacus, Missouri

Hi, there is evidence that using marijuana while pregnant--whether smoked or injested another way--can be harmful for the fetus. Using marijuana while breastfeeding is also a bad idea. Yes, marijuana is addictive; among those who start at a young age, 17% become addicted. The best thing is to avoind using it!

-Emily Jones

Drugs are bad for my health and me growing? Right?

-chamneess_a, Oregon

Hi Cham,
When you are still growing, you are more vunerable bad effects of drugs. And if these drug effects impact your developemnt, those change could stay with you the rest of your life. We are doing a lot of research on this topic, but we are very concerned about the impact of drug on younger people, as they are still growing and developing.

can you get high off sniffing products with chemical

-NOR5K1, Illinois

Hello and thanks for participating in Chat Day! Products such as glues, nail polish remover, lighter fluid, spray paints, deodorant and hair sprays, whipped cream canisters, and cleaning fluids are widely available yet far from being unharmful. Many young people inhale the vapors from these sources in search of quick high without being aware that using inhalants, even once, can have serious health consequences. See more information at the link below. We hope this is helpful!

-Emily Einstein

can you get high off things that aren't drugs or anything of the sort? Such as sharpies or other things with those fumes

-thekingofcats, California

Using inhalants, such as spray paint, markers, sharpies, or cleaning supplies, can result in nerve cells not being able to do their job, which can cause loss of coordination and lead to permanent difficulty with basic actions such as walking, bending, and talking. So, things that you might not think of as drugs are still chemicals and have chemical effects on the brain and body.

-Carlos Blanco

can you get high off Tylenol or other sleeping meds?

-bigdre26, California

Hi Bigdre26,

By Tylenol, if you're referring to acetaminophen, it is unlikely to cause a high. Sleeping meds don't cause a high but will do the opposite. Sleeping meds will likely cause you to be drowsy or calm you which is why it's often prescribed for those suffering from anxiety or sleep disorders.

-Jinhee Lee

Can you get high on all drugs, or only certain ones?

-Molly, Illinois

There are many kinds of drugs; some are illegal and sold by drug dealers, some are medicines, and some are both. Yes, you can get high on some drugs, but not all. When you can get high on a drug, that means it has "psychoactive" properties. Of course, those are the drugs that people misuse because they like the feeling they get. However, you can also get addicted to psychoactive drugs, so it is a risky choice. After awhile, you no longer feel good from the drug; you take them simply to avoid the pain of withdrawal.

-Meyer Glantz

Can you get impotence because of drug abuse?

-Percy Jackson,

Hello Percy -- The answer is yes. Drugs affect different people in different ways, and this can definintely be one side effect.

-Meyer Glantz

can you give me some tips to quit smoking???

-its me,

Congrats on deciding to quit! Talk to your friends and have them help you through moments of cravings and withdrawals. Quitting isn't easy, but it can be done and it's worth it. For more tips and resources to stay tobacco free go here: https://teen.smokefree.gov/

-Suzanne Lim

Can you have a heart attack because of drugs if so why does this cause a heart attack?

-4176, Illinois

Good question, 4176! Yes, drugs can cause heart attacks. Cocaine, meth, spice, and steroids all have been linked to heart attacks. Stimulant drugs, like cocaine and meth, cause a massive release of norepinephrine that can cause the heart to be overstimulated and cause sudden death.

-Kurt Rasmussen

Can you inject alcohol

-Chungus, Illinois

Technically, it is physically possible to inject alcohol, but the effects would be disastrous! It wouldn't take much to kill a person that way. Highly highly dangerous!!

-Aaron White

can you list ALL illegal drugs just to be safe??

-dash, Illinois

Hey dash! Great question! You can find information on most drugs at the NIDA website: https://teens.drugabuse.gov/drug-facts. Great that you want to stay away from drugs! Also make sure to not take anything that a friend offers you if you don't know what it is.

-Roger Little

Can you OD (overdose) on marijuana?

-nursedawn, Maryland

Thanks for the question, nursedawn! Any substance can be poisonous in a large enough dose. The increased availability of marijuana products has led to an increase in accidental poisoning of young children. Now that marijuana is being sold in so many forms, it's easier than ever to overdose. Here's more information: https://www.drugabuse.gov/publications/marijuana-facts-teens/letter-to-t...

Can you OD on acid?

-Deeltus, Oregon

Hi Deeltus - Acid (LSD) is a very powerful drug. As for overdosing, it depends on what you mean by that. It is very difficult to kill yourself with LSD in terms of overdosing, but you can certainly have extremely serious effects on your cognition, mood, and perception, which can be very disturbing and unpleasant.

Can you OD on ACID?

-Deeltus, Oregon

Hello Deeltus,
In theory you can OD on any drug. Acid or LSD is especially dangerous because it alters your perception of reality, so you can put yourself in danger or possibly hurt or kill someone else if you are driving while you are under the influence of this drug. Even if you do not OD, these drugs are made in unregulated illegal labs and so they can have toxic chemicals that can cause health problems. Some people experience "bad trips" where they have anxiety or panic while having disturbing hallucinations.

Can you OD on marijuana?

-BGCN-Nowata, Oklahoma

Hello BGCN - Nowata! Thanks for participating in Chat Day! Information about what can happen if you use marijuana can be found at the link here: https://www.drugabuse.gov/publications/marijuana-facts-teens/want-to-kno.... Marijuana intoxication can, in rare cases, produce a temporary psychosis. There are no reports of people fatally overdosing (dying) on marijuana alone. However, people can feel some very uncomfortable side effects, especially when using marijuana with high THC levels. There are reports of marijuana users seeking treatment in emergency rooms, reporting unease and shaking, anxiety, paranoia, or hallucinations, and in rare cases, extreme psychotic reactions. Learn more about drug overdoses among youth. However, marijuana use can increase risks for accidents and injuries (impacts of drugged driving are discussed here: https://teens.drugabuse.gov/drug-facts/marijuana. We hope this is helpful!

Can you over dose on Ibuprofen??

-Kaden, California

Yes, you can take too much ibuprofen. Taking too much can lead to stomach and intestinal damage, including severe GI bleeding which can even be fatal. Always follow the instructions included with over the counter medications when taking them.

-Marsha Lopez

can you over dose on marijuana and if you use it for pain and can it hurt u in anyway other way then affecting your lungs

-Tas, Montana

Hello Tas,
In theory you can overdose on any drug. The availability of increasingly potent marijuana and edible forms and oil extracts make this more likely. In fact, there has been an increase in accidental poisonings of infants and pets with these products. Risk of overdose is independent of the purpose it is being used for. We don't know all of the ways that the many chemicals in marijuana may affect the brain and other organs, we know that some of the active chemicals are fat soluble, so they accumulate in the brain and other fatty tissues and is release over time. For more information, see: https://www.drugabuse.gov/publications/drugfacts/marijuana
