More and more young people are using heroin these days, and sometimes they start using it because they’ve gotten addicted to prescription painkillers.

One study showed that people who abuse painkillers like OxyContin are 19 times more likely to start using heroin. The study also found that 8 out of 10 people who started using heroin abused painkillers first.

Killing More Than Just Pain

Heroin and painkillers belong to the same class of drugs: opioids. Opioids attach to specific molecules called opioid receptors, which are found on nerve cells in the brain, spinal cord, intestines, and other organs. When painkillers or heroin attach to these receptors, they can decrease the feeling of pain. Opioids can also cause a person to feel relaxed and happy, which can lead some people to abuse the drugs.

Opioids have many negative effects. Painkillers and heroin can cause sleepiness, constipation, and, depending on the amount taken, affect a person's ability to breathe properly. In fact, taking just one large dose of painkillers or heroin could cause a person’s breathing to stop, sometimes killing them.

Why do people switch from painkillers to heroin? In an effort to cut down on painkiller abuse, changes have been made to laws and prescription drug tracking systems. Because it’s getting harder to get painkillers, people may turn to heroin because it is cheaper and easier to get.

The Danger in Abusing Painkillers or Heroin

Not everyone who abuses painkillers starts using heroin, but even painkiller abuse alone can hurt you. Opioid drugs of all kinds can be very addictive. Addiction is a disease where you feel like you need to use a drug even if that drug is hurting you and messing up your life. Addiction is caused by chemical changes in the brain after drug use.

When someone is addicted to painkillers or heroin, it is very difficult for them to stop using the drug. People trying to stop using opioids after they are addicted may have withdrawal. Some of the effects of opioid withdrawal are restlessness, muscle and bone pain, trouble sleeping, diarrhea, vomiting, cold flashes with goosebumps, and uncontrollable leg movements.

there are more facts to this and teens need to be more aware thank you for this post.
And how many people that used pain pills weren't addicted and this happen 2

Most people using heroin started with prescription opioids. However, most people using prescription opioids do not switch to heroin. In fact, less than 4 percent of people who abuse prescription opioids switch to heroin. (You can read more about that here:

At issue is the very large number of people being given prescription opioids. Even if a fraction switch to heroin, it represents a very large number of people. And even if they don’t switch to heroin, many die by overdosing on the pills (about 19,000 people a year).

It's an epidemic that people are living in pain because a Dr is in fear of prescribing pain meds to control that pain! It is no wonder the drug problem has gotten so bad! What do you expect? People are tired of living in agony and knowing that nobody cares! Such a sad state of affairs when I care for cancer patients writhing in pain as they take their last breath! We treat dogs better than humans! As long as the medical society ignores our cries and don't give us pain control, you'll see increases in illegal heroin and morphine sales in addition to black market vicodin and oxycontin sales. People will do what they will to survive through the pain not for a high but to work and live without pain. It is a right of life to live without pain. Don't you agree that it's time to bring our legal prescriptions back to the public??
Yes you are right! My pain management are cutting back my pain meds for no reason at all, if they lower them anymore I might have to resort to heroin to control my severe neuropathy pain! Sad!
People who live in pain suffer. I've had back surgery and a very bad car accident. I steal try to work,I maintain with painkiller pills. I use to Go to my doctor every 3 months for pain med. Now I have to go every30 Days. I don't think that is right. That's Time from my job, that's the same amount of money to pay 3 times as much.and ect.. If u are in pain the kinda pai. That will always be with you tell the end, you rely on somethin to help.
The government has no interest in anyone's rights. They are only concerned with what they are doing and their numbers and related items. Get them out of our lives and we will all be better off. In the last 100 years name ONE thing government has done by getting into our lives that has improved our lives, just one.
Healthcare. Exit.
Word !! You r so right. Government should stay out of our lives . They know nothing about pain. They should all all pain on scale of 7/10 and for 24:7 maybe then they would realize we don't want drugs , all we want is complete pain relief & our quality of life back

Actually, the National Institutes of Health has a large consortium of experts who focus on pain and pain management. A lot of research is being done to find safer and more effective ways to treat pain. See

Uh, civil rights? Woman's right to vote? Have you been living under a rock or are you too doped up to know any better?
Yes i agree insuffrr behond excuriating pain daily i cry even scream .I hate living in pain I cant live a normal life it is so wrong that I had brain surgies I suffer pain constantly I had more operstions I had bone takennout of my brain I had deep brain surgies I had so many different operations and nothing helped my pain made a hundred times worst.I had a decompress trigimal nerve nothing I have so many different medical . Problems thst cost pain but my doctor put me on methodone that dont take awayb pain. I hate my lifebin pain its like a nightmare
I am also on methadone. It works really well for me. You need a DNA profile. My pain mgmt doc gave it too me because nothing else was working. Results showed a poor metabolized for a lot of the pain Meds.
DNA profile? That's interesting. I worry about my meds not working right due to no gallbladder and gastroparesis. Maybe I need to ask about this because they just want to cut you back even when your pain isn't going down.
I feel you. I have had the same treatments with the same meds.They're working but I hope it lasts.Be well.:-)
Yes I do ! Not everyone is wired to be addicted . We just want to live normally without agonizing pain
I agree with you Debbie 100% . I'll be looking for a drug dealers if I can 't get my oxycodone from my doctor.
Yes you are 100% right.. if they would understand people with legitimate pain need their meds then they wouldn’t have so many going to street drugs. Stop giving people a hard time it’s ridiculous .. most people do not abuse their medications.. this is an eodrnic because the doctors are not taking care of people in pain..
I couldn't agree more with you about this, I lay in bed days at a time now because my doctor doesn't write scripts anymore for me and I'm in very bad health and only 44 years old, I don't want to live most days
As our government tightens up the supply of prescription painkillers in order to "help" the public avoid becoming addicted to these painkillers it encourages the public to switch to heroin. How does that work? Heroin is readily available and cheap due to the available supply. Then the public determines that heroin is easier to obtain and gives them a better 'high' so they switch over permanently. It is almost like our government works for the heroin dealers. I said 'almost'. This is what the War on Drugs has accomplished, a bunch of heroin addicts has been created by the US government. How disgusting. In addition, the legitimate users of the FDA approved meds for pain have a hard time getting their prescriptions filled. How much worse could it be? Get the US government OUT of the narcotics business because, as usual, they have no clue what they are doing and what damage they are causing. It is awful to watch. By the way, heroin so-called 'overdose' deaths are caused because the addicts never know what the strength of what they are buying is. When they inject it they are playing Russian Roulette. After/while you are injecting you do not know if you are going to die until you do or don't. That is how you find out. Sounds like fun. There is no agency making sure that the strength of drug (heroin) you buy from your local drug dealer is what you thought it was. If it turns out to be too strong, well, I guess you die. That is what our government has done and they keep on doing it. They are just so damn helpful. Maybe they should go help with something else, like paint or water like they did in Flint, Michigan.
I am a 79 year old woman who has never been addicted to anything. I have back and knee pain. I was getting two 5 mg hydrocodone a day until I tried marijuana to be able to get to sleep at night. For that reason my doctor canceled my hydro prescription. I think this is what drives people to heroin.
way to damn many and some of them really need these meds to live a somewhat normal life
I spent my whole life without addiction until I turned 37 and a car wreck I was introduced to pain meds I took them 4 years and finally gave in to heroin then ruined my life completely I just got help been clean two weeks now omg I'm finally free
Exactly. Let's be honest with numbers here I can say drinking gasoline kicks people no duh. Opioids kill just like aspirin can guns kill people don't. So if the person abuses it they would have abused anything. There is no safe prescription pain killer so stop taking it away from those it helps and are responsible
When I was a pharmaceutical representative in 2003 I had to attend a training seminar about pain medication prescribing in which we compared heroin to prescription pain pills. We were taught that on the seventh consecutive day of taking either a pill or shooting up heroin, the human physiology is to become physically dependent to the point of having to feed the habit, to stave off the sickness, or become violently ill in going through the long withdrawal period. This was not made clear in the marketing of oxycontin. All pain pills that contain a derivative of morphine are subject to the same danger of addiction as heroin and until we educate the public and get the physicians to prescribe correctly, 5 day on with a 3 day wash, we will continue to have the addiction to pain pills and the crossover to heroin epidemic that we are swimming in today.
Are you going to be educating the heroin dealers too?
UR CRAZY IF U THINK I'M DOING THAT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!AND ITS SAD IF U DO :(
take away pain kills people will just goto what they can find and that heroin. this "drug war" is a losing battle. drugs aren't the main problem its the consequences of making them illegal.
You are exactly right. Most people know this. It is intuitive and accurate. Why doesn't our useless government know this? In the last 100 years name one thing and I mean ONE thing that the government has ever done by mixing into people's lives that benefited people. Just name one thing. I am laughing because you will not even be able to come up with one damn thing. It is disgusting. This War on this and that. Nothing they do benefits anyone but them. It gives them high paying jobs and big pensions and free medical. Gives us headaches. Best thing that ever could happen for us is to fire them all or give them work that does not involve us. I pray for it daily. I ask God to take the government out of my life. I hope he hears that, so far he hasn't.
Not strong enough with regards to "one large large dose of pain killers or Heroin could cause a person to stop breathing, somtimes killing them. The ignorance regarding all the factors is killing more and more young people. Half-Life of any medication needs to br publicized. Body size, weight and age as well as gender. Metabolism if each is individual is completely different and unique. I received a call, wrong number, from a 18 year old female who's friend died from an "accidental" overdose of Clonazepam and heroine, age 19, by the hand of her 24 year old boyfriend. He didn't call for help. I spent a long time talking and explaining why this "accident" ended her life. EVERYTHING I explained to her, I would ask, "Have you ever been told or were aware of this?" Her answer was always "no" By the time I finished explaining Half-Life, body type, and metabolism, she stopped crying. Education on physiology of the human body, metabolism and the build up of drugs, even in a weekend of abuse for a 100 pound young girl, will potentially kill you. As it did to her friend. RUSSIAN ROULETTE is the game they're playing. Because it's all about fun to the uneducated young who live for fun in the moment. Ignorance because no one is Teaching them. One time. One weekend. They haven't any idea how much their body has remaining in it's system from the last time. They feel fine. "CUMULATIVE" and Half-Life need to be yelled from every high school. Daughter/sister to Anesthesiologists'. Ever Vigilant, my dad would say about his medical field. Constantly and endless recording and even observation of the color of his patients fingernails.
your doctor will consider your health history, age, physical condition, life stressors and other factors to determine which medications may be right for you. Some medications may be prescribed only during the detoxification period, when your body is adjusting to the absence of heroin.
I was addicted to oxycotin and as my need for them got greater I could not keep up with the demand my body needed to function. I got so tired tired tired of witwithdrawal. Bad enough when your supplier were your own parents, it was there monthly medication. Their doctor had no problem writing 300+ for oxy/dros/dilaudid each meds for each of them. So we became full blown addicts right along with other people who would get pills from them as well. So one month after I had taken my last oxy and your body not ok but it jolts when you hear ive no more. I think you get sick faster than anything. Well i remember being hours in my withdrawal my mother said I can help you out but dont ask no questions. I had no problem with not asking, I just want the pain to go away. She took my arm tied it up and because I trusted my mother I didnt know she was about to introduce me to herion.
My God, how could she do her own child like that???
It really is a struggle I started out taking oxys and opanas then I started them. But the pills got sparse and expensive when I could find them, and believe it or not the needle is more addictive than the pills. If you've never shot up you wouldn't understand (also if you've never shot up don't ever try it) but when shooting up pills you end up with a lot of fillers and b.s. in your veins, which is no good. But then there was heroin, easy to find, if you get good stuff its not as bad for your veins as the pills, and it is a lot more potent. I used to crave the pills but that was nothing compared to how ungodly sick I got when I couldn't get heroin. Not to mention all the friends that I've watched fight it for years, many of which now have hep c, many have lengthy prison sentences for what they did while desperate to get high, and sadly many of my friends died fighting this addiction. Its no joke trust me I made my mistake and im still struggling to get away from it. I hope at least one person will read this and decide never to go near heroin or people who are doing it, because you'll end up just like them if you're around them long enough. Herion addiction is a terrible life long struggle that has taken many of my friends lives, and if you go down that road chances are you'll never find your way back
Wow good thing you made the right choice on the end
Will you email me please? I get this may be weird but I can't comment

Thanks for the info

I'm addicted to pills. Just got woken up 5 hours into my sleep by withdrawals. Couldn't go back due to the crazy hot flashes, sweating, then freezing, goosebumps, restlessness, the need to change position every few minutes after getting comfortable, nausea, everything hurts, negative thoughts, I get crazy nightmares also when I withdrawal. So I decided to do some internet surfing. Anyhow, this is only an hour or two into the withdrawals. I popped 2 pills just now and I'm waiting for them to subdue. It's not enough to get high, I just want these symptoms to calm down.
I'm so sad for you. I hope you over come this addiction. I am praying for you Lena.
How can we get you the help you need to kick your habit?
I take morphine and the dr writes me out a prescription for 60: 60mg extended release and 120: 10mg extended release and also 4 bottles of morphine solution per month at 10mg/5ml concentration. (600mg in each bottle). (I had a 75ug fentanyl patch before the morphine) I wouldn't say I'm full blown addicted but I would say 100% that I am dependant on the medicines. I take them for chronic pain and it scares me the thought of not having them for pain and also the withdrawals that will happen if I do stop taking them. I'm prescribed 80mg slow release twice a day and upto 80mg of oral solution a day. It is true tolerance to strong opioids builds fast and the way it says "a big dose can kill" if someone with no tolerance tried a fentanyl patch it even warns them on the box that it's only for people with opioid tolerance. I will also say do not start using painkillers unless you really need them! I remember when they first gave me codeine, then dihydrocodeine, then tramadol then after a few years on that it was onto the fentanyl patch then finally now where I'm on morphine. I live in the uk and here it's harder to get opioids but they still prescribe them. If I could rewind the clock and start from fresh I wouldn't take them. The side effects are horrific the nausea and constipation are the worst. Some days when the pain is bad I will take 200-250mg of extended release tablets in the morning then take my usual 80mg at night. Before I started opioid therapy I used to see heroin addicts as junkies and smack heads but now I am dependant on an opioid I can definitely see how there is a bigger picture and how 80% of heroin addicts start out on painkillers. I have always said to my self as soon as I start to feel the pendulum is swinging from dependance to addiction is when I tell the dr straight away. I live in England and here the problem of teenagers getting prescribed painkillers and turning to heroin isn't as bad as we don't have to pay stupid prices for our prescribed medicines. All we have to pay is £8.05 per item so for them 3 items it is £8.05 x 3. Also I am age 22 and take the morphine (along with other non opioids like Lyrica and amitriptyline.) for back pain, hip pains, knee pain and they don't know what it is. This website has a lot more info than the UK website talk2frank has.
You don't pay "stupid prices for Rx"? How do you figure that? Let's compare our tax rates to yours, shall we? Keep believing Big Bro is taking good care of you and everything is "free for mee". You may not be personally paying outright for drugs. But, make no mistake, you ARE paying for it!
I don't understand? Was there physical pain first and no relief and the heroin helps like Advil? I thought heroin was taken to disappear from reality. Zone out. What does it mean to get high? And when a pain killer makes someone sleepy, is that getting high, too?

When we talk about "getting high," we mean a rush of relaxed and happy feelings that come from drugs' effects on the brain. Sometimes that includes feeling sleepy, and sometimes not. Opioids and Advil work in different ways. Heroin and opioid pain relievers both attach to molecules in the body called opioid receptors. That blocks pain messages being sent to the brain, and typically makes users feel high and zoned out. (Advil, on the other hand, works by reducing swelling.) Some people abuse prescription opioid drugs -- that means taking them to feel high, not because a doctor prescribed them for pain -- and get addicted. If they can't get more prescription opioids, they sometimes start using heroin, because it affects the same part of the brain as prescription opioids. Unfortunately, both heroin and prescription opioids can be very dangerous and even deadly if abused. You can read more about how different drugs work here:

i have been taking prescription drug for 15years i tryed advil 8m I.B for a year did not help it just missed with my insides really bad so i started pain pill it help my pain then i got cancer and it went up when i was getting treat i saw kids in there to so sometimes pain pills are a good thing and the pain i have will never go away so i do understand what u are saying but there are people who ake only what they need
The article said, "In an effort to cut down on painkiller abuse, changes have been made to laws and prescription drug tracking systems. Because it’s getting harder to get painkillers, people may turn to heroin." It's quite interesting that the Taliban had almost completely eradicated the poppy fields in Afghanistan until the U.S. invaded - they are now back up to almost 100%. The government has begun a smear campaign and is cracking down hard on legitamate doctors and on patients who need pain medication. The TV is full of commercials about the "dangers of prescription opiods". Facebook is flooded with ignorant memes about the pharmaceutical companies that make legal pain meds and the pharmacies that sell them. Is it a coincidence that you can go online and see pics of U.S. soldiers gaurding the poppy fields at a time that the streets are flooded with heroin? Is this why it's hard to legally get pain meds? he streets are flooded with heroin.
Don't take them!!!!!!!!!!!!! Heal Naturally!!!!!!!! They are fake,and they make you a fake person!!!
