can u overdose on alchol

-chief_tru706, Maryland

Definitely.  Alcohol poisoning occurs from a single episode of drinking way too much and you can potentially die from alcohol poisoning. Alcohol builds up in your bloodstream and can slow down important body processes like breathing and the gag reflex, which prevents you from choking. Even if you have stopped drinking or pass out, alcohol in the stomach and intestine can continue to enter your blood stream and circulate throughout your body.
Critical signs of alcohol poisoning include:

  • Mental confusion
  • Stupor
  • Coma
  • Vomiting
  • Seizures
  • Slow or irregular breathing
  • Hypothermia, or 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. You can learn more about alcohol poisoning and overdoses at:

can ur baby be effected by smoking

-seahawks boss 1, Georgia

Hi! Very important question. Tobacco is NOT safe to use in pregancy because it affects the developing baby.  You can read about the effects here: the good news is that the sooner a pregnant woman stops smoking, the better the outcome for her baby. It's also important not to smoke around the baby after birth because he or she can have health problems from secondhand smoke.

Can you die from drinking alcohol?

-DavionH, Texas

Absolutely! Too much alcohol from any source -- beer, wine, liquor, -- can shut down the parts of the brain that keep us alive, leading to death. 
If you drink enough alcohol, parts of the brain that are important for keeping us alive can shut down. Then, the heart can stop beating and we can stop breathing. In essence, it's like alcohol flips a switch and shuts the body off. This is what's known as "alcohol poisoning."

It is also important to point out that having any alcohol at all can increase the chances of dying from injuries, such as falls, drownings, or car crashes.

It's also possible to die from long-term abuse of alcohol. The liver can become enlarged and inflamed and ultimately stop working.

can you die from hookah?

-TayDalto, Michigan

I guess so...especially if you drop the coal on you and catch fire! Ok that was a joke (a bad one), but on a serious note, many think that smoking tobacco through a water pipe (hookah) is safer than smoking a cigarette, believing that the water filters out the harmful chemicals.  That’s a myth! Hookah smoke contains the same harmful tar and other toxic chemicals that cigarette smoke has. Hookah smoking is linked to many of the same health problems as cigarette smoking—like heart disease and lung cancer. In addition, a typical hour-long hookah session, in which a person inhales several long, deep breaths of smoke, can equal as many as 100 cigarettes or more. Click here

can you die from huffing

-cassidyb, Texas

Yes, inhalants can be lethal. Sniffing highly concentrated amounts of the chemicals in solvents or aerosol sprays can directly cause heart failure within minutes. This syndrome, known as “sudden sniffing death,” can result from a single session of inhalant use by an otherwise healthy young person.

Can you die from marijuana?

-SCARface, Michigan

Morning SCARface,
Not directly, but marijuana raises your risk of car accidents. People die from marijuana in indirect ways, same as with other drugs.

can you die from smoking

-daquan, Maryland

Hi Daquan!

Yes, you can die from smoking. Cigarette smoking is responsible for more than 480,000 deaths per year in the United States, including an estimated 41,000 deaths resulting from secondhand smoke exposure. This is about one in five deaths annually, or 1,300 deaths every day. As you can see, its better not to even start smoking!

can you die off drugs

-Denayzha, Georgia

YES! For example, 17,000 people die from prescrition opioids each year. Plus even if you do not overdose, some drugs can kill you, but it takes time.  About 440,000 people die each year from diseases related to smoking.

can you die the first time you take inhalants

-AshyumP, Texas

Yes, inhalants can be lethal. Sniffing highly concentrated amounts of the chemicals in solvents or aerosol sprays can directly cause heart failure within minutes. This syndrome, known as “sudden sniffing death,” can result from a single session of inhalant use by an otherwise healthy young person. High concentrations of inhalants may also cause death from suffocation, especially when inhaled from a paper or plastic bag or in a closed area.

Can you get addicted to caffeine., Pennsylvania

Hi  9 out of 10 adults and 3 out of 4 children, teens, and young adults use caffeine it daily too—in the form of soda, coffee, and energy drinks.  That’s right, caffeine is a drug—a stimulant drug, to be exact. It’s even possible to be physically dependent on it—which means that a person who is used to drinking lots of caffeinated beverages can experience withdrawal symptoms if they quit. While most people do not become addicted to caffeine, try to take it easy on the caffeinated drinks...drinking a lot of them can make your heart race, make it hard to sleep or more.  Have a great day and check out NIDA information on

Can you get addicted to cocaine?

-SCARface, Michigan well as any drugs, frankly. Addiction occurs because drugs "hijack" the brain resulting in a chemical change that results in uncontrolled craving. Even marijuana- contrary to what many believe- can be addictive. Drugs work on the brain - not worth taking that risk in my humble opinion! check out for more info. Dr. Jack

can drugs make you commit suicide?


Yes, some of the new "fake weed" products and "bath salts" have caused severe psychotic reactions and caused some users to attempt suicide. Definitely stay away from those!

can drugs make you go mentally insane

-bryancornelius, Texas

Dear bryancornelius,

Thank you for your question. Continued drug use has been linked to symptoms of mental illness, and also linked to increase risk of psychosis in marijuana users, as one example. High doses of marijuana can produce a temporary psychotic reaction (involving hallucinations and paranoia) in some users. On the other hand, mental disorders can lead to drug abuse as many people self-medicate. Patients suffering from anxiety or depression may rely on alcohol, tobacco, and other drugs to temporarily alleviate their symptoms.

Thank again, and best wishes! There is a lot of information about the health effects of drugs on NIDA’s teen site here:

can drugs make you mentally insane

-brianluna, Texas

I'll re-state your question. Do drugs cause mental illness? We know that drugs affect the way your brain functions. This can change a person's personality. Stimulant drugs (cocaine, methamphetamine) can also make people hyper. These drug effects can make it look like the person is "crazy".   There has been research on Marijuana and mental illness: that shows that long-term marijuana use is associated with a number of mental conditions, including schizophrenia, psychosis, depression, anxiety, and suicidal thoughts or attempts. However it is not yet clear whether marijuana use directly causes or exacerbates these conditions. Currently, the strongest evidence is for the link between marijuana and psychosis.  Marijuana intoxication can, though rarely does, produce a temporary psychosis, and it may play a role in the development of schizophrenia in vulnerable individuals especially those with increased genetic risk.

can drugs make your blood thin?

-keshawn14, Georgia

The only drugs that I know of that will make your blood thin are pharmaceuticals designed for that purpose and usually given during surgery or to people with heart disease and atherosclerosis. So if anyone tells you that aspirin, Plavix, or heparin has psychoactive properties, they are lying to you.

-Nancy Pilotte

Can drugs make your blood thin?

-abriannamedeari, Georgia

Hi Abriannamedeari,

Interesting question. There are drugs that are prescribed by doctors to "thin" blood, but those drugs don't make you high or aren't drugs you can become addicted to. Aspirin is also a blood thinner, but again aspirin is not considered to be a drug of abuse. To find out which drugs are addictive, and how they effect your body, click on this link:

Can drugs make your brain swell?

-Snowfluff102113, Michigan

That's an interesting question. The first thing that I think of is that drugs can trigger an immune response, just like a bacterial infection. This can recruit additional immune cells into the brain, and may promote more fluid into the brain that could cause increased swelling. But in general, I haven't heard that drugs cause that much swelling. Thanks for asking.

Can drugs make your penis small?

-Billy, Minnesota

Uh, no, but steroids can shrink your testicles---which is where your testosterone comes from.  That is why abuse of anabolic steroids (steroid molecules based on the structure and pharmacology of testosterone) can lead to impotence.

can drugs prescribed by doctors still kill brain cells like other unprescribed drugs?

-tollestudent15, Ohio

Yes, for example, pain killers that contain opiates such as vicodin or oxycontin can lead to respiratory depresssion, which if not taken care of, can kill cells in the brain from lack of oxygen,

can every drug kill you

-Lions Adv., Texas

Hi Lions
Yes, but in different ways. for example:
inhalants can suffocate and kill you after a single dose
marijuana can impair your driving and get you involved in a fatal crash
heroin can force you to use a contaminated needle and get you AIDS
steroids can make you depressed and suicidal.

as you can see there many ways for drugs to kill you.

better safe than sorry.

-Ruben Baler

can heroin kill you

-cassidyb, Texas

Oh yes, cassidyb, heroin can kill you. If the dose is large enough, it can stop your breathing, leading to death. But even if it doesn't kill you it is dangerous to take.  Taking heroin can change your brain so that you become addicted and don't feel pleasure anymore from things that are usually enjoyable.  Find out more about it here:

Can hookah pens harm you in any way?

-ChristianMedina, Texas

Hi Christianmedina!H ookah pens are really just one name for electronic cigarettes, or e-cigarettes. These are battery-operated devices that many people think are a safer alternative to conventional cigarettes...and their use is growing in popularity. E-cigarettes often contain nicotine and produce a flavored aerosol that looks like tobacco smoke but without the tar produced by burning tobacco leaves. While e-cigarettes do not produce tobacco smoke, it is still unclear how safe they are. They can still deliver nicotine, which is a highly addictive drug, which poses a significant risk for teens to become addicted. Also, the aerosol from some e-cigarette products were shown to contain known carcinogens and toxic chemicals including formaldehyde. Until more studies are conducted, there is no way of knowing what the short and long-term health consequences of repeated exposure to these chemicals may be. Want more information on e-cigs?

Hi 1Dmusikluver - Hookah is just another way to smoke tobacco.  Nicotine in tobacco is addictive, so I don' t know if you'll become addicted to hookah, but you can become addicted to nicotine.  Check out more NIDA resources on hookah at -

Can i die from Vape?

-SlayerofSauron, Michigan

Hmmmm... that's a really broad question. I'm assuming you aren't talking about accidently ingesting the e-nicotine liquid (although that has unfortunately happened and resulted in death). Electronic cigarettes are new to the scene and we don't have a lot of scientific data on their safety or effects yet.  While they may be advertised as "safer" than cigarettes, there is a lot we don't know about the health consequences of e-cigarettes.  There have been a few reports of e-cigarettes exploding when people use them causing some serious injuries to their hands and faces. The bottom don't know what you are getting in these products or their health consequences. Best to wait until we get more information---and it could take a few years before we see good research studies on e-cigs.  For more information see:

Can I Drink Wine if I Take Lipitor?

-Walter White, Michigan

For a healthy adult, it is probably okay to have a glass of wine now and then while taking Lipitor, but this is something the person needs to discuss with his/her doctor. Obviously, teens should not be drinking alcohol! 

-Aaron White

can i eat weed?

-EmilyBlue, Maryland

Hello Emily Blue--Yes.  You can also eat dirt, rocks, and worms but why would you?  Yuck. But if you want to know if you can eat it and feel the high, yes, pretty much like people do that eat it when its baked into brownies or candy.  Often there is a time lag between when you eat it and when you feel the effects, which can cause some people to take too much and get very, very ill and feel psychotic.  So--bottom line just because you can, you still shouldn't.
