Think twice before you take over-the-counter cold/flu medicine, warns pharmacist
Highly addictive, amphetamines such as speed and ice can cause by illicit manufacturers to make and distribute a range of amphetamine as pseudoephedrine (found in cold and flu tablets) and household chemicals.and full how to clean horse hooves what to do with leftover sweet and sour meatballs
Skip to: Main Navigation Main Content. Highly addictive, amphetamines such as speed and ice can cause long-term physical and mental health problems. Amphetamine-type stimulants ATS are produced both in Australia and imported from overseas. In recent years, consumers have rated ATS as relatively easy to access. But like many illegal drugs, where there is no quality control, the content and potency, and therefore risks, can vary from one batch to the next. ATS are among the most commonly used illicit drugs in Australia.
Pseudoephedrine PSE is a sympathomimetic drug of the phenethylamine and amphetamine chemical classes. Pseudoephedrine is a stimulant , but it is well known for shrinking swollen nasal mucous membranes, so it is often used as a decongestant. It reduces tissue hyperemia , edema , and nasal congestion commonly associated with colds or allergies. Other beneficial effects may include increasing the drainage of sinus secretions, and opening of obstructed Eustachian tubes. The same vasoconstriction action can also result in hypertension , which is a noted side effect of pseudoephedrine. Pseudoephedrine can be used either as oral or as topical decongestant.
Amphetamines are stimulant drugs, which means they speed up the messages travelling between the brain and the body. Some types of amphetamines are legally prescribed by doctors to treat conditions such as attention deficit hyperactivity disorder ADHD and narcolepsy where a person has an uncontrollable urge to sleep. Other types of amphetamines such as speed are produced and sold illegally. The more potent form is crystal methamphetamine ice. The appearance of amphetamines varies. Amphetamine powder can range in colour from white through to brown, sometimes it may have traces of grey or pink. It has a strong smell and bitter taste.
By Tegan Taylor. It's hard enough to tell your pseudoephedrine from your p henylephrine even when you're not sick. Your head feels like it's been stuffed with cotton wool and your throat like you've swallowed a thousand razors. Achy-jointed and bleary-eyed, you stare at the pharmacy shelf, wondering what combination of potions and pills might help you feel human again. How do you know which medicines will work, and which ones will make you feel wired, drowsy, or do nothing at all? Colds are caused by one of hundreds of strains of virus, usually rhinovirus or respiratory syncytial virus.
Certain cold and flu medicine ingredients can have harmful side effects, if you are taking prescription medications. It can actually be much worse as well, if they are combining those remedies with alcohol or other medications that are hard on the liver such as cholesterol-lowering drugs.
How Meth Works
The production of methamphetamine — and the desire to consume it — is seemingly unstoppable. When precursor chemicals are brought under tight control in one country, like the United States, production simply moves to another country, such as Mexico. When Mexican authorities clamp down, it moves farther south, or into Europe or Asia. Then, the finished product is shipped right back into the very countries that have waged such a battle to eradicate it in the first place. Most meth smuggled into the United States is made in large labs — "superlabs" — in Mexico. There are many small meth labs in operation in the United States, but these mostly serve to feed the habits of the amateur cooks themselves. The production of methamphetamine has been made more difficult by federal regulations, like the Combat Methamphetamine Act of , aimed at controlling the flow of precursor chemicals such as ephedrine and pseudoephedrine found in some cold remedies , as well as other necessary components.

The process of buying over-the-counter cold-and-flu medicines, and the types of products available, has changed in recent years. The partnership resulted from concerns about the raft of problems associated with significant increases in the use and abuse of psycho-stimulant drugs, commonly known as amphetamine-type substances or stimulants. It was thought that increases in drug overdoses, hospital admissions, illegal laboratory seizures, and related crime problems such as armed robberies and ram-raids on pharmacies stemmed from pseudoephedrine being used to make illicit stimulants, such as methamphetamine and ecstasy. These substances stimulate the central nervous system by increasing synaptic concentrations of three major neurotransmitters in the brain — dopamine, serotonin 5-HT and noradrenaline.
