Addiction cure Your message explores a mix of substances, addiction mechanisms, and the question of whether addiction can be cured. Let’s address each point clearly and scientifically: --- 🧪 1. "Smoking cure is hexane, ethylene alcohol, rehabilitation, every sour thing" — Is this true? Not exactly. Here's a breakdown: Item Comment Hexane ❌ Toxic solvent, not a cure — used in industrial processes, not for human treatment. It can damage the nervous system if inhaled or consumed. Ethylene Alcohol ⚠️ Likely a confusion: You may mean ethanol (found in alcohol) or ethylene glycol (found in antifreeze). Neither is a treatment for addiction — both are dangerous if misused. Rehabilitation ✅ Yes. Rehab programs, therapy, and medical support are the primary treatment paths for smoking and drug addiction. Sour things ⚠️ Not a cure. Some sour foods (like citrus) may help reduce cravings by altering taste receptors, but they don’t cure addiction. --- 💊 2. How Do Opioids Work? ✅ Corre...

Economic paradoxes

Sure! Here's a list of 100 economic paradoxes, each in one concise line: 💰 1–20: Classic & Popular Economic Paradoxes Paradox of Thrift – More saving reduces overall savings in a recession. Jevons Paradox – More efficiency in energy leads to more total consumption. Gibson’s Paradox – Interest rates rise with prices, not inflation. Lucas Paradox – Capital doesn’t flow to poorer nations as expected. Productivity Paradox – Tech improves, but measured productivity lags. Easterlin Paradox – More income doesn’t always mean more happiness. Voting Paradox – Rational people vote despite it not being individually beneficial. Leontief Paradox – The U.S. exports labor-intensive goods despite being capital-rich. Paradox of Value – Water is vital but cheap; diamonds are useless but expensive. Backfire Effect – People may double down on beliefs when given facts. Paradox of Plenty (Resource Curse) – Natural riches often lead to slower growth. Tragedy of the Commons – Shared resources get over...
