What is Moonshine Blindness? – Moonshine blindness has two ugly sides. First of all, there is the propaganda that was spread around the 1920s when governments attempted to stop people from producing their own moonshine. A lot of effort went into prohibiting the production of moonshine.
Many cases of poisoning and blindness were spread to discourage moonshine brewers despite that many of these cases were not related or were false. And then there is the real cause of moonshine blindness. Moonshine blindness can occur when someone consumes too much methanol. When methanol is consumed, it is changed into formaldehyde and is known as methanol poisoning.
Methanol poisoning can cause damage to your eyes and can even result in blindness in severe cases.

What alcohol causes blindness?
Alcohol Addiction Increases the Risk of Blindness The type of alcohol that has the potential to cause blindness is methanol. These substances can immediately damage the nervous system, including the eye nerves. Initially, it causes inflammation, followed by the death of nervous system tissue, which can cause blindness and lead to death.
- The alcohol content of alcoholic beverages varies.
- Most types of alcoholic beverages that are drunk are types of ethanol compounds with the molecular formula C2H5OH.
- This type of alcohol can affect the central nervous system, so when it is drunk, it will certainly cause the person consuming it to lose consciousness, and in severe conditions, it can cause death.
In the manufacture of adulterated alcohol (self-mixed), it is often mixed with methanol (CH3OH) or benzene (C6H6). These materials can also cause poisoning and cause permanent nerve damage (blindness or death). The mixed material has been fused with alcohol and cannot be separated or decomposed.
- Methanol is a type of chemical substance that can cause blindness and paralysis when it enters the body.
- In mild cases, benzene causes a deficiency of erythrocytes (a condition when the level of red blood cells in the body falls below the normal range) and leukocytes (a condition when the number of white blood cells in the body falls below normal).
Meanwhile, in severe cases, benzene will cause nausea and even death due to heart and respiratory system failure. For cases of sudden blurry vision, an ophthalmologist will provide maximum therapy in the form of high-dose drug injections. The therapy given aims to reduce swelling of the optic nerve due to methanol or alcohol intoxication.
Individual responses vary from therapy given; if it is not too late, sometimes visual acuity can improve, but if there has been total tissue damage, it will be difficult to return to normal so that blindness occurs. We cannot predict the occurrence of death. However, alcohol that has been mixed with methanol is very dangerous when consumed.
Consumption of 70% alcohol that has been mixed with methanol can cause blindness and paralysis. In severe cases, it can cause cardiac arrest and death, and the cases are quite common in our society. Of course, many types of cancer are also triggered by alcohol consumption.
- Alcohol consumption can trigger cancer in several areas of the body, including the mouth, esophagus, throat, larynx (part of the respiratory system), and liver.
- In the human body, alcohol will activate several types of enzymes that trigger the development of cancer cells.
- Alcohol will also damage the DNA in the body so that some parts of the cells will grow and multiply uncontrollably.
Given the dangers that can cause everything from blindness to death, it is appropriate for all of us to stay away from alcohol and start living a healthy life without it. : Alcohol Addiction Increases the Risk of Blindness
Can ethanol make you go blind?
Will Drinking Moonshine Make You Go Blind? In 1919, in anticipation of Prohibition’s impending doom, the pioneering New York toxicologist Alexander Gettler warned officials of an observed uptick in homemade stills across America. This was worrisome. “One of the things that he deeply feared was an epidemic of blindness,” says Deborah Blum, author of The Poisoner’s Handbook: Murder and the Birth of Forensic Medicine in Jazz Age New York, a book about Gettler.
- In the 1920s, that in fact happened.” Indeed, between 1920 and 1933 tens of thousands suffered paralysis or blindness through the consumption of homemade hooch.
- Hundreds, it is estimated, perished.
- So yes it’s true: moonshine can put your lights out.
- But why? Look no further than CH 3 OH, or methanol.
The chemical is considered the simplest form of alcohol, merely a methyl group linked to a hydroxyl one. But that simplicity doesn’t equate to weakness. Quite the opposite. “Only ten milliliters of methanol consumption can cause permanent blindness,” asserts Dr.
- Bruce Goldberger, chief of forensic medicine and director of toxicology at the University of Florida’s College of Medicine.
- In color and odor, methanol closely resembles ethanol, the kind of alcohol that’s human-safe.
- The only catch is: “If you drink as much methanol as ethanol, you’ll die,” Goldberger says.
So it pays to be scrupulous here. The reason for methanol’s toxicity lies in our metabolism. Ethanol, when consumed, is broken down by the body into two harmless compounds, carbon dioxide and H 2 0. Methanol, on the other hand, becomes formaldehyde, which is nasty stuff.
One of the first parts of our nervous system that this poison attacks is the optic nerve. A natural byproduct of the distillation process, methanol is normally removed from liquor. But mistakes happen—a shoddy ‘shiner might leave it in by mistake. A still also could be constructed of poor materials, allowing dangerous chemicals like lead, which has also been linked to, to leach in.
Paramount when consuming moonshine safely is being aware of where it came from. Thus, Blum, who grew up in Georgia and Louisiana, recalls a rule that her father lived by: “Know your ‘shiner.” You also want to know what is actually being distilled. Moonshine’s origins harken back to the late eighteenth century, when Scots-Irish flocked into the hills of Appalachia and brought their liquor recipes with them.
- Corn mash was typically used, but you can put any organic matter into a still—one infamous case from the Prohibition era involved shiners in Tennessee caught distilling poison ivy.
- Again, know your ‘shiner,
- Today, with a special license and fee, moonshine is to produce in America; incidents of the kind experienced in yesteryear are few and far between.
But elsewhere in the world, in places like Pakistan and India that have liquor bans, drinking disasters are commonplace. One tragic accident in involved more than 100 fatalities from a bad batch of hooch. So remember: “Unless the source is reputable,” stresses Goldberger, “be cautious about drinking moonshine.” : Will Drinking Moonshine Make You Go Blind?
Why do moonshiners throw away the head?
Heads – When distilling, you should separate, or cut, the heads, hearts, and tails. The head of the distillate is the first portion of the run. You can recognise it by its smell. It has an unpleasant smell like nail polish or methylated spirits. You throw away the heads or you can keep it to use as a fire starter for your BBQ.
Is moonshine a methanol?
Methanol: The Toxic Side Of Moonshine – You may have heard stories about the dangers of moonshine, or any illegally distilled liquor. The real culprit of these true stories, however, is methanol. Methanol, or methyl alcohol, is a byproduct of the distilling process.
Why does methanol damage eyes?
Pathophysiology of Me-ION – Toxic exposure to methanol can result in damage to the optic nerve and to both the outer and inner retinal layers, while damage to the latter being generally more pronounced. Additionally, further parts of the visual system such as chiasm and optic tracts may also be affected (Grzybowski et al.2015 ).
In humans, even slight chronic exposure to low levels of methanol (0.87–1.0%) associated with severe malnutrition, especially in conjunction with a deficiency of cobalamin (vitamin B12) and folic acid—vitamins involved in the metabolism of methanol and its metabolites, can have dramatic consequences and result in the development of optic neuropathy.
That was postulated in the leading hypothesis explaining the causes of the outbreak of the Cuban epidemic optical neuropathy (CEON) in 1992–1994, which affected 50,000 individuals, nearly 0.5% of the entire Cuban population (González-Quevedo et al.2018 ; Hedges et al.1997 ; Sadun 1998 ).
- Previous human and animal studies have shown that systemic exposure to blood formic acid levels above 7 mM persist for more than 1 day may lead to long-term adverse visual effects (Eells et al.1996 ).
- Importantly, animal studies have also shown that the distribution of toxic metabolites of methanol is characterized by varying intensity within the tissues.
In rats, after 60 h after intoxication lasting 48 h with both low (4–6 mM) and high concentrations of methanol (8–15 mM), the highest concentration of formic acid was detected in the vitreous, retina, and blood, respectively. It is worth emphasizing that the concentration of formate in the optic nerve was five times lower than in the retina (Eells et al.1996 ).

Last Updated: February 17, 2022 Last Reviewed: February 17, 2022 Chapter Information Unit conversion table: see Table 19.3-1, Methanol (wood alcohol, wood spirits) is used in industry, in window cleaning products (particularly as a windshield-washing fluid), as fuel, and in paint thinners. It cannot always be discerned by taste and smell from ethanol, which results in poisonings of persons consuming counterfeit alcohol products (containing methanol instead of ethanol). Methanol is rapidly absorbed from the gastrointestinal tract, distributed to the body water, and is not protein bound. Maximum blood levels are observed within 30 to 60 minutes from ingestion. Toxic methanol levels have also been reported after significant dermal exposure and concentrated inhalation. Methanol is metabolized by alcohol dehydrogenase about 10 times slower than ethanol. About 2% to 5% is excreted unchanged by the kidneys and 10% to 15% through breath. Mechanism of toxicity : Methanol is a central nervous system ( CNS ) depressant that produces an inebriation like that of ethanol. Methanol is metabolized by alcohol dehydrogenase to formaldehyde, which is then converted to formic acid by aldehyde dehydrogenase. Severe metabolic acidosis develops secondary to formic acid accumulation as well as from lactate production due to inhibition of mitochondrial cytochrome c oxidase by formic acid. Formic acid accumulation can cause irreversible blindness from damage to the retina and optic nerve. Toxic dose : The consumption of as little as 10 mL of pure methanol may result in permanent loss of vision and as little as 30 mL may be lethal. Typically the lethal oral dose of pure methanol is in the range of 30 to 240 mL (20-150 g), with the median lethal dose being 100 mL (~1-2 mL/kg). At the bedside, a toxic volume of methanol can be calculated (in mL) as 15 × the patient’s weight in kg divided by the % of methanol in the ingested fluid. For example, a toxic amount for a 100 kg patient who ingested a 50% methanol solution would be (15 × 100)/50 = 30 mL. Clinical Features Top 1. Symptoms of early poisoning : Initially, before methanol is metabolized, it causes CNS depression and intoxication symptoms similar to those of ethanol. It may also cause gastritis.2. Symptoms of late poisoning : After a latent period of 18 to 24 hours the metabolites of methanol accumulate and cause an anion gap metabolic acidosis. Visual disturbances, blindness, coma, and acute kidney injury with myoglobinuria may result. Patients describe visual disturbances as blurred vision, haze, or a “snowfield.” Fundoscopic examination of these patients may reveal hyperemia of the optic disc or retinal edema. An afferent pupillary defect is a bad sign. Patients may have tachycardia, tachypnea, and altered mental status from advanced acidosis. With massive methanol overdoses, pulmonary edema and cardiovascular collapse may occur. Acute hemorrhagic pancreatitis is not uncommon in patients with methanol overdose. Some long-term survivors of methanol poisoning report parkinsonism-like extrapyramidal symptoms. Diagnosis Top The clinical diagnosis of methanol intoxication is suggested by the history, symptoms (particularly visual changes), ocular physical examination, and an anion gap metabolic acidosis in the presence of an osmolar gap. Diagnostic Tests 1. Specific testing for serum methanol, although not always readily available, is helpful as methanol levels >6.25 mmol/L (about 20 mg/dL) are considered toxic; levels >12.5 mmol/L (40 mg/dL) are very serious. Optic nerve damage correlates with levels >20 mmol/L and usually occurs at levels >30 mmol/L (100 mg/dL). Levels >150 mg/dL are potentially lethal. If available, serum formate concentrations better reflect the degree of toxicity, since a low or normal methanol level may reflect nearly complete conversion to formic acid.2. Other suggested investigations include measurement of levels of electrolytes (with anion gap calculation), blood glucose, blood urea nitrogen, creatinine, serum osmolarity (and osmolar gap calculation ), arterial blood gas, lactate level, ethanol level, and lipase (if pancreatitis is suspected). A large anion gap not accounted for by lactate may be a clue to a potential toxic alcohol ingestion. High beta-hydroxybutyrate levels may suggest alcoholic ketoacidosis as the cause or contributor to the anion gap. Treatment Top 1. Decontamination : There are no known methods of decontamination. Activated charcoal does not adsorb methanol but may be worthwhile if coingestion of other drugs or toxins is suspected. If ingestion of a large volume occurred within 20 to 30 minutes of presentation, aspiration of gastric contents may be performed.2. Antidotes and specific therapies : By competitively inhibiting alcohol dehydrogenase and methanol metabolism, the amount of formaldehyde and formic acid produced can be limited. Therapy is indicated for patients with a methanol blood concentration >20 mg/dL (~6 mmol/L), and, when methanol levels are unavailable or delayed, should be used in patients with an anion gap metabolic acidosis and osmolar gap not accounted for by ethanol or a history of methanol ingestion with an osmolar gap >10 mOsm/L. Note that both ethanol and fomepizole are reasonable first-line agents for toxic alcohol poisoning. Despite the higher direct cost of fomepizole, we suggest its use due to ease of administration and reduced need for monitoring. Weak recommendation (benefits likely outweigh downsides, but the balance is close or uncertain; an alternative course of action may be better for some patients). Low Quality of Evidence (low confidence that we know true effects of the intervention). Quality of Evidence lowered due to lack of experimental head-to-head comparisons and only indirect data from observational studies. For discussion on ethanol vs fomepizole in toxic methanol poisoning, see Appendix 1 at the end of the chapter. Beatty L, Green R, Magee K, Zed P. A systematic review of ethanol and fomepizole use in toxic alcohol ingestions. Emerg Med Int.2013;2013:638057. doi: 10.1155/2013/638057. Epub 2013 Jan 31. PubMed PMID: 23431453; PubMed Central PMCID: PMC3574646.1) Ethanol : Administer as early as possible, orally in a conscious patient or IV in an unconscious patient, to a target blood ethanol level of ≥20 mmol/L (>100 mg/dL, ie, 1%) but <40 mmol/L (~200 mg/dL). When given orally, start with a loading dose of 1 mL of 95% ethanol/kg followed by a maintenance dose of 0.1 to 0.2 mL of 95% ethanol/kg/h. If pharmaceutical-grade ethanol is unavailable, commercial alcohol (typically 40% alcohol, 80 proof) can be given as a loading dose of 2 mL/kg and a maintenance dose of 0.2 to 0.4 mL/kg/h. The loading dose will need to be adjusted if the patient has coingested ethanol and the maintenance dose doubled during dialysis. Parenterally ethanol is typically given as either a 5% or 10% solution of ethanol in 5% glucose (dextrose). The less concentrated solution is administered in a bolus at 15 mL/kg over 30 minutes followed by a maintenance dose of 2 to 4 mL/kg/h, and the higher concentration is given at half the bolus amount and half the maintenance rates. The maintenance rates will need to be doubled if the patient is on dialysis. Sometimes ethanol is added to the dialysate.2) Fomepizole (4-methylpyrazole, 4-MP) is a competitive inhibitor of alcohol dehydrogenase and an easier-to-use antidote than ethanol, associated with greater convenience but also a higher cost. It is loaded at a dose of 15 mg/kg (up to 1.5 g for patients >100 kg) diluted in at least 100 mL of normal saline or 5% glucose and administered IV over 30 minutes. This is followed by 10 mg/kg every 12 hours for 4 doses and then increased to 15 mg/kg every 12 hours until methanol levels are <6 mmol/L (20 mg/dL). Since fomepizole is dialyzed, the dosing frequency is increased to every 4 hours during dialysis.3) Folic or folinic acid (the latter preferred, especially in liver disease) can hasten the conversion of formate into carbon dioxide and water. A commonly suggested dose for either is 1 mg/kg (up to 50 mg) given IV every 4 hours.4) If toxic alcohol levels are unavailable and the contents of the product ingested are unknown, we recommend treating for ethylene glycol toxicity as well (see Ethylene Glycol ).3. Accelerated elimination : Hemodialysis is very efficient at removing methanol and formate. Indications for dialysis include: 1) A methanol level >15 mmol/L (50 mg/dL) and/or an osmolar gap >10.2) Visual symptoms, coma, or seizures.3) Acute kidney injury or concomitant renal failure.4) Suspected methanol ingestion with metabolic acidosis (pH ≤7.15) or an anion gap >24 mmol/L.5) Ongoing metabolic acidosis not responding to bicarbonate therapy. Typical dialysis endpoints are a methanol level <6 mmol/L (20 mg/dL) and normalization of anion and osmolar gaps.4. Supportive care aims to maintain vital parameters and correct any disturbances.1) Ensure airway patency. Intubate and assist ventilation if necessary.2) Treat coma (glucose, thiamine) and seizures (benzodiazepines) if they occur.3) In the presence of acidosis, toxic organic acids are protonated into uncharged molecules, making them easier to penetrate tissues (like the retina) and less likely to be excreted in urine. Formate can be converted to formic acid (thus reducing retinal exposure) by treating metabolic acidosis (pH <7.3) with IV sodium bicarbonate dosed depending on results from ongoing blood gas measurement. Note that local poison control centers do not universally endorse bicarbonate use. AppendiX Top No head-to-head trials have been reported on the subject of whether ethanol or fomepizole is better for toxic methanol poisoning. In one systematic review both ethanol and fomepizole have been safely used for methanol and ethylene glycol intoxication. Fomepizole is higher priced but ethanol is more difficult to administer and requires greater staffing costs, frequent monitoring, and the need for a critical-care bed. Administration of fomepizole may negate the need for dialysis in patients without renal failure or profound acidosis but further research is needed. Both ethanol and fomepizole are reasonable first-line agents for toxic alcohol poisoning but fomepizole is easier to use.
Does methanol get you drunk?
What are the signs of methanol poisoning? – The earliest signs of methanol poisoning can be hard to distinguish from the normal effects of alcohol. You can develop mild symptoms similar to alcohol intoxication within an hour, along with nausea, vomiting and abdominal pain.
After 12 to 24 hours, the more significant symptoms can develop, such as headache, dizziness, vertigo and blurred vision. “The bad thing is that it takes 12 to 24 hours, and often people have been solidly drunk and sleeping,” says Gordian Fulde. Ignorance of the issue can also lead to misdiagnosis or critical delays in diagnosis.
If eye symptoms such as blurred vision or difficulty looking a bright light develop, then “they really are in trouble,” says Fulde. “That’s when they really need to do something.”
Does methanol burn in eye?
Eye Contact Methanol is a mild to moderate eye irritant. High vapour concentration or liquid contact with eyes causes irritation, tearing and burning.
Do blind people dream?
People Who Went Blind After Ages Five to Seven – People who went blind after ages five to seven tend to have visual dreams. That said, they might not experience as much visual dream content as fully sighted individuals. Like people who went blind at a younger age, those who went blind later often have other sensory elements become more prominent in dreams to make up for the reduced visual content.
- For example, they tend to experience more tactile or physical sensations while they dream than sighted people do.
- The visual dream experiences blind people have aren’t only of people and places they saw prior to going blind,
- While dreaming, they see things that have entered their life since they’ve become blind.
This suggests that while we dream, our minds construct a world rather than replicating one we are familiar with, since someone with complete sight loss doesn’t truly know what something they’ve never seen visually looks like. What happens during sleep is similar for both blind and sighted people, although many blind people experience fewer visual images while dreaming. Both groups experience dreams that involve lifelike stories in which they are an actor, having sensory experiences, and interacting with others.
- Although their visual dream content is reduced, other senses are enhanced in dreams of the blind.
- A dreaming blind person experiences more sensations of sound, touch, taste, and smell than sighted people do.
- Blind people are also more likely to have certain types of dreams than sighted people.
- For example, blind people seem to experience more dreams about movement or travel and more nightmares.
Like sighted people, blind people experience nightmares, Research has found that blind people have more dreams about travel that involve unfortunate circumstances. Some of these dreams could potentially be considered nightmares. One hypothesis is that the nightmare content may mirror the difficulties blind people face while getting around in their waking life.

Does blind man see a dream?
Sighted people often experience vivid, colorful dreams, so it is natural for them to wonder, “Do blind people dream?” The answer is yes — blind people do dream — though their dreams are different from sighted individuals. In the absence of sight, the dreams of blind people tend to be full of touch, sound, smell, and taste, sensations which generally occur less often in the dreams of sighted people.
Can a blind guy cry?
Yes! And even if they lost or severely damaged part of their eye/eyes, as long as the tear duct remained safe or intact then they can still produce tears.
Can alcohol ruin my vision?
Long-term effects of alcohol on your vision – Long-term effects of alcohol abuse can have detrimental consequences on your vision and eye health. In extreme cases, toxic amblyopia, the result of a toxic reaction in the optic nerve which causes permanent vision loss.
- Excessive alcohol may increase your risk of age-related macular degeneration ; WHO’s report revealed that the average person’s daily consumption is 33g of pure alcohol, which is the equivalent of 2 glasses of wine.
- A study in Australia revealed that drinking more than 20g of alcohol a day results in a 20% increased chance of developing early AMD compared to those who consume no alcohol.
Poor diet and over-consumption of alcohol may also be related to developing cataracts, Prolonged alcohol abuse will eventually affect your vision through vitamin deficiency. The liver can only process so much alcohol at a time and heavy drinking can affect the absorption of vitamins in the liver which are needed to maintain healthy eyes and good vision.
How much alcohol Love is Blind?
From wine to vodka, there aren’t restrictions on what the cast members are allowed to drink. Hey, have you ever been on a sober blind date?
Is night blindness caused by alcohol?
How Alcohol Affects the Eye – One reason alcohol impedes night vision with prolonged use is that it decreases your ability to absorb vitamin A, Vitamin A is one of the most important nutrients for preserving your vision. This means that if you already have night vision issues, those issues are exacerbated by the alcohol in your system.
- The higher your blood alcohol level is, the more your night vision is affected.
- Alcohol can also impede your night vision in the short term.
- The agent in alcohol that affects the human brain is called ethanol.
- Ethanol impairs your vision by flowing into the tear-film of your eye.
- This distorts the quality of the images you see.
The alcohol disturbs the covering of the eye called the tear-film, which destroys the quality of the images you see. When the tear-film deteriorates, the quality of all the images you see deteriorates as well. Add that mess to the normal glare from traffic on the highway and you can understand just how difficult it is to drive at night after you’ve had a few drinks.
What alcohol has methanol?
Methanol is an alcohol that is found in all distilled beverages (such as tequila, whiskey, mezcal, etc.) in different proportions. This alcohol is considered an unavoidable compound in distilled beverages, since it is formed from the fermentation of pectins originating from the raw material with which the distillate is produced.
