Methamphetamines
Methamphetamines are a type of highly addictive and illegal drug that can produce feelings of intense happiness, energy, and alertness. They are also known as "speed" or "crystal meth" and are usually taken orally, snorted, or injected. Methamphetamines work by releasing high levels of dopamine, a neurotransmitter that regulates feelings of pleasure and reward, in the brain, leading to a rapid increase in heart rate, blood pressure, and body temperature. Long-term use of methamphetamines can cause significant physical and psychological damage, including cardiovascular problems, malnutrition, and psychosis.

Methapyrilene
Methapyrilene is a drug that was previously used as an antihistamine and an antiallergy medication. It works by blocking the action of histamine, a substance released by the body in response to allergies, infections, or other inflammatory conditions. This helps to reduce symptoms such as itching, sneezing, runny nose, and redness of the skin, which are often associated with allergic reactions.
Methaqualone
Methaqualone is a medication that was previously used as a sedative and hypnotic, typically prescribed for insomnia and anxiety. However, it has a high potential for abuse and addiction, and its use is currently restricted in many countries due to its potential for dependence and negative effects on brain function. It is also known for its recreational use as a hallucinogen and anxiolytic, often combined with other substances like marijuana or psychedelics. The effects of methaqualone include feelings of relaxation, euphoria, and distortion of perception, but it can also lead to adverse effects such as amnesia, dizziness, and nausea. Due to its harmful misuse, the production and distribution of methaqualone have been banned in many countries, and its use is considered illegal.
Methcathinone
Methcathinone is a stimulant, a type of drug that is classified as a controlled substance. It primarily affects the central nervous system, producing a sense of euphoria, increased energy, and a feeling of being "high". It is often used illegally as a recreational drug, and its use can lead to addiction, health problems, and legal issues.
Methedrine
Methedrine is a brand name for an amphetamine-based medication, specifically a central nervous system stimulant. It was historically used to treat conditions such as narcolepsy, attention deficit hyperactivity disorder (ADHD), and obesity. The medication works by increasing the activity of certain neurotransmitters in the brain, resulting in increased alertness, energy, and concentration. However, due to its potential for abuse and addiction, the use of amphetamines like Methedrine is now heavily regulated in many countries.
Metheglin
Metheglin is a type of sweet mead that originated in Wales. It is a fermented beverage made from honey and spices, and is characterized by its sweet and slightly effervescent flavor. The term "metheglin" is derived from the Welsh words "met" meaning "honey" and "glin" meaning "spice", reflecting the drink's main ingredients.
Methemoglobin
Methemoglobin is a form of hemoglobin that has had its iron atoms oxidized from the ferrous (Fe2+) to the ferric (Fe3+) state. This can occur when hemoglobin is exposed to certain substances, such as nitrite-containing compounds like food or water, or certain medications. Methemoglobin can bind to oxygen, but it cannot release it to the body's tissues as efficiently as normal hemoglobin, which can lead to a decrease in oxygen delivery and potentially serious health problems, such as anemia, cyanosis, and shortness of breath.
Methemoglobinaemia
Methemoglobinaemia is a clinical condition characterized by an abnormally high level of methemoglobin in the blood. Methemoglobin is a form of hemoglobin that has lost its ability to carry oxygen due to a reduction of its iron from its normal ferrous (Fe2+) form to its ferric (Fe3+) form. This can occur due to various factors such as exposure to certain drugs, chemicals, or infections, and can lead to cyanosis (a blue-gray discoloration of the skin and mucous membranes), shortness of breath, and other complications.
Methemoglobinemia
Methemoglobinemia is a medical condition characterized by an abnormal increase in the amount of methemoglobin in the blood. Methemoglobin is a form of hemoglobin, a protein in red blood cells that carries oxygen to the body's tissues. In healthy individuals, methemoglobin makes up a small percentage of total hemoglobin. In methemoglobinemia, the presence of excessive methemoglobin can lead to a decrease in the amount of available oxygen being carried to the body's tissues, causing symptoms such as shortness of breath, fatigue, and bluish discoloration of the skin and mucous membranes.
Methenamine
Methenamine is a type of organic compound that is commonly used as a building block in the synthesis of other compounds, particularly in the production of pharmaceuticals and dyes.
Methene
Methane is a naturally occurring gas that is the main component of natural gas. It is a colorless, odorless, and highly flammable hydrocarbon gas that is lighter than air.
Methenolone
Methenolone is a synthetic anabolic-androgenic steroid (AAS) and a derivative of dihydrotestosterone (DHT). It is commonly known by its brand name Primobolan and is typically used in the treatment of muscle wasting diseases, such as HIV/AIDS, and as a performance-enhancing drug in bodybuilding and athletics.
