Meth Mouth and Crank Bugs: Meth-a-morphosis

Sara Bellum

The SBB has already told you about some of the nasty effects that methamphetamine can have on the body—remember that post about how scavengers won’t even eat the dead bodies of meth users?

Not only can meth mess up your body’s chemical structure and even cause problems with your heart and lungs, it also changes your appearance and behavior. Soon, meth users might not even look or act like themselves.

Bad news for teeth and skin

Ever heard of “meth mouth?” It isn’t pretty. Meth reduces the amount of protective saliva around the teeth. People who use the drug also tend to drink a lot of sugary soda, neglect personal hygiene, grind their teeth, and clench their jaws. The teeth of meth users can eventually fall out-even when doing something as normal as eating a sandwich. As if that’s not bad enough, meth can also cause skin problems-and we’re not just talking about regular zits.

Take a look at these pictures from the Department of Justice—but beware, they are disturbing!

Meth users’ skin can start to look like this because they frequently hallucinate—or strongly imagine—that they’ve got insects creeping on top of or underneath their skin. The person will pick or scratch, trying to get rid of the imaginary “crank bugs.” Soon, the face and arms are covered with open sores that could get infected.

No peace of mind

In addition to the “crank bug” hallucinations, long-term meth use leads to problems such as irritability, fatigue, headaches, anxiety, sleeplessness, confusion, aggressive feelings, violent rages, and depression.

Users may become psychotic and experience paranoia, mood disturbances, and delusions. The paranoia may even make the person think about killing themselves or someone else.

A lot of people dont research the negative effects of drugs until they go through with it. Just to clarify, it feels worse than it sounds!
If you do use meth and you end up with real bed bugs in your hair they are sucking your blood which means they too are effected by the meth, which makes almost impossible to kill them
I have been one of the common users of meth,but vow to the live of God that I will never ever in the rest of my life time use drugs again.
My sister takes meth everyday and heres and sees things. that only exists in her own mind..She starts trouble with family and smokes it around her kids and stashes the drugs in her kids room!!!!!
I heard that there's a "parasite"that methamphetamine drug use causes... Does anybody know about this so called parasite, if this is true, and what it's called?

We don’t know about any parasite caused by meth.

This is Really Gross, If People Are Smart And Know About meth And How The "Crank Bugs" Then Why Dont they just not let it get to them because they should know better

crystal meth controls the brain and how they think. they cant just "not let it get to them"
I am surprised that everyone still says that the "Crank Bugs" that meth users experience are hallucinations. There is a very real physical thing happening to them which is causing the intense itching. To say they are imagining it is just naïve. Many things can happen to the physical body that may be only determined by a microscopic analysis. When micro capillaries near the surface of the skin dilate unexpectedly or burst, it is very itchy and feels like being bitten by a bug. If you look at where it itches, you can see nothing to cause it. Another very possible cause (in my opinion) is that the meth is causing a die-off of parasites in the user's body that is causing intense, unrelenting itch. Doctors who specialize in this field say that most first world humans have numerous undiagnosed intestinal and blood borne parasites that are rarely uncovered unless blood and stool exams are done. When known anti-parasitic medicines or herbs are taken, the human host will experience a number of symptoms when the parasites are being killed. Google "Herxheimer Reaction". If scavenging animals want nothing to do with a dead meth-poisoned body, it may be that any dormant or active human body parasites are being poisoned, too. If the meth is causing a blood-borne parasite die-off, the microscopic debris can exit through the skin causing intense itching. If intestinal parasites are being attacked by the meth, they give off distress chemicals that flood the system of the host. One of these symptoms is extreme skin itching that is intense and cannot be relieved by normal means. Asking the miserable addicts to just "not let it get to them" is not even reasonable. Could you say this to someone covered in poison ivy or 100 large mosquito bites? I think not. Another possible cause for the itching is scabies, which can be found in less than hygienic conditions. Just because you can't see it with your naked eye, doesn't mean there isn't an actual cause for this.
I've experienced the nightmare of bird mite infestations more than once. I once lived by a duckpond and got them on my legs every time I walked outside, and later on, I picked up a baby bird that fell out of a tree and got them on me again. I also had some kind of scabies-like or mange-like mite on my cats many times. They get into the laundry too, and that was a problem for me because in the past, I didn't do the laundry very often, but I absolutely had to wash the laundry all the time after I got the mites. There are other people on the internet writing about bird mite infestations. They are an unimaginable nightmare to anyone who hasn't experienced it. Some kind of itch mite also lives on public seats, usually seats covered in fabric which cannot be washed, wiped, or removed - I get them badly every time I go to the movie theater, and I get them from sitting on toilet seats. As long as you can keep your laundry clean, and wash your bed blankets a lot, and cover your mattress with a plastic mattress cover, AND cover your car seats, and on and on and on... all of which is hugely expensive and takes a lot of time and effort... then the infestation will be reduced and become tolerable. I imagine a person surviving the chronic poisoning of meth use would not be able to do all those things. Plus, when you scratch these mites, it leaves permanent scars, and I am not a meth user - although I came to this page while looking to see if anyone else on the internet had ever written about "ephedra contamination," which I also experienced - I had to throw away all my belongings after merely touching the SEEDS of the ephedra plant, which I had intended to grow inside my apartment years ago, and the toxic oils of the plant go through your skin, causing all the horrible side effects of ephedra, such as permanent insomnia, absolute insomnia which will never, ever stop unless you wash all the ephedra contamination off of your body. I could not buy anything expensive, and still to this day I keep all my belongings in cardboard boxes and plastic bags, and have very few belongings. The ephedra ruined my life. So I imagine that someone living with meth use, meth contamination, and bird mites WOULD indeed have huge, unhealed wounds all over their skin, and it's NOT a hallucination.
Bed bugs and scabies are REAL.....and can be in a bad batch.....nice tactics......dont do drugs
It is the same as itch scratch syndrome. Your high you scratch it gets dry and itchy again you scratch more it becomes dryer and raw or scratched open... healing skin itches more so you scratch and start over.
It's not bugs it's the poison they are putting in their body getting out the only way it can the pores of the skin it leaves sores because it's burning them hints the itching. I myself have been on the receiving end of users abuse and neglect watched users go through withdrawal claim they aren't using and call me the liar and every other name under the sun why people would choose to do this to themselves is beyond me I don't feel sorry for them they chose it and they are the ones who lose everything my mom chose to support her husband's habit for it and her own rather than raise her three children my husband claims he's not using but I have been on the receiving end of users before I have no interest in using and I wish that all users could see it from this side the ones . Who love or loved them and feel what we do when you come down from your high and abuse us because you aren't high on it anymore. Using these drugs makes your child(ren) your spouse your family feel like they aren't enough for you and even though it hurts the user they hurt their loved more than the drug hurts the user. If you use it you tell your children and spouse you don't love them and they aren't enough for you simply by using the user don't have to say . It to us we feel that way because of how we are treated by the user
It's mold some one has either intentionally or unintentionally let the meth go to long and it molded when heated it causes the fungus to activate so to say. When smoked using a water bong look for the Tobacco looking things and there You'll find yourself a moldspore
its rare to think your seeing anything without 5days up & typically hearing things comes first . the drug makes u sweat & able to sweat without feeling or seein ur own sweat, this witha cold temp an bad hygiene creates a film on the skin made of chemicals, pops and sugar products not eatin anything but small foods now drys the mouth an digestive system , dry teeth rub an spread bacteria that thrive when not consuming water & food (due to lack of saliva produced for lack)
If you were ever addicted to something, you would not question addiction so lightly. Once addicted, your addicted brain thinks for you and all the brain knows (once addicted) is it needs more drugs/alcohol/prescription meds as well. So do your homework on addiction of all kinds before you ask that question again
There has to be something to this method mite thing. Too many people that have used are saying the same thing and drugs aren't going to make that many people react in the same manor and see the same things. Cone on people use your brain. And what right does anyone have to judge another person when first off no one is perfect and we all mistakes, number two you don't have a clue what a person has endured to get to the point of using numbing their self, and three isn't only God that has the right to judge us. You should always try to help one another instead of tearing someone down to where they are ashamed and won't seek help. A person may end up dying because of what you careless people say. Think before you act we all bleed the same and were supposed to all be brother and sisters so help one another. That's whats wrong with this world today!!!

Say if i knew about crank bugs and then later on i used Meth... would i still have the effect of seeing the crank bugs..????
Thanks:) !

@Abs123--hmmm, interesting question. I really don't know what causes the hallucinations or if you can psyche them out...but, the scary part is with these hallucinations, people really think they're real! So, my point would be since we know about crank bugs and all of the other things that could happen with meth, who would anyone even want to try it?

I've had them for quite a while even before I ever touched meth or heard of them. I work in the medical field so I have access to very strong microscopes. /They are real and what's a little scary are those black dots are SOMETHING LIKE NANO ROOTS BUT They are actually 2 "dots"- ACTUALLY 2 CONNECTED Y A STRING OR PART IF THEIR BDY and a large one and a smaller one.. They appear TO BE NANO ROBOTS OR FROM AN Alien planewt < I am nor joking. They are alsointelligent. I AM NO LONGER SCARED OF THEM. In fact I try to protect they CANNOT stand sunlight. There is so much more. IF anyone knows what I i'm talking ABOUT PLEASE REPLY.! IF i DO METH IT'S SNORTED 3-4 TIMES week. 1 or 2 swam all snorts.
Ey you're right man..I've seen them too. I was thinking the same thing about them having an alien origin..they are intelligent and aggressive. I've videod some before. I believe the doctors know they're real but are puzzled by it and are keeping the public blind and calling them hallucinations.
No, I know from experience..unfortunately, n my is a picker..it's frikin gross..lol but I don't pick, I just rub my eyes till their raw..
yep it is the same
I'm a mother who never knew what meth was I'm only on here trying to see why I never knew the sign of my son being addicted to this drug its to late now I lost him 3 weeks ago nothing in this world could ever hurt me the this has my heart is broken
Iam sorry for your lost !! Will keep you in prayer !!
Sorry to hear of your loss but dont take on the guilt of not knowing. Addicts can often be the best con artists and not necessarily saying your son was. What i am saying is many addicts are extremely good at hiding their addiction. I will prey that you have more peace in your life.
Hi there- I am also a mother to a child who is no longer with me in this physical life...not from the same cause but I can relate to your pain and know how alone it can be to loose our babies. I am not being inaccurate in assuming that your son lost his life not just his spirit/self/mind right? Either loss is devastating, which can go unsaid , no doubt. I just want to clarify as I am trying to learn more about this disease so I may save a loved one from peril....however I can be of service...
So sorry!
well but of course
I'm glad someone is brave enough today the truth .yes there are meth Biggs fr the poison ,but there are a lot of mites on birds ,mice and others .aost 70%of Americans are infected with one kind or another .our gov and cdc know it and are lying .knowing the truth would cause mass hysteria!
I saw them but I told myself that they're not real and that I needed to keep cleaning.
Yes, you absolutely could have the effect of "seeing" the crank bug. I knew of the crank bugs before I ever used meth, and yet I ended up experiencing and becoming convinced that there were parasites in my skin. I could see them actually see them moving. Don't use meth
