A drug, broadly speaking, is any substance that, when absorbed into the body of a living organism, alters normal bodily function. There is no single, precise definition, as there are different meanings in drug control law, government regulations, medicine, and colloquial usage. In pharmacology, a drug is "a chemical substance used in the treatment, cure, prevention, or diagnosis of disease or used to otherwise enhance physical or mental well-being." Drugs may be prescribed for a limited duration, or on a regular basis for chronic disorders. Recreational drugs are chemical substances that affect the central nervous system, such as opioids or hallucinogens. They may be used for perceived beneficial effects on perception, consciousness, personality, and behavior. Some drugs can cause addiction and habituation. Drugs are usually distinguished from endogenous biochemicals by being introduced from outside the organism. For example, insulin is a hormone that is synthesized in the body; it is called a hormone when it is synthesized by the pancreas inside the body, but if it is introduced into the body from outside, it is called a drug. Many natural substances such as beers, wines, and some mushrooms, blur the line between food and drugs, as when ingested they affect the functioning of both mind and body. From Wikipedia under the
GNU Free Documentation License What is the blood brain barrier and what drugs are capable of crossing it? Q. If anybody can help me out with this subject matter, that would be great! I know the blood brain barrier is a tight seal of endothelial cells that prevents many chemical substances and bacteria from entering the brain. (is there anything else I shoould know about it?) Also, what kind of drugs are able to penetrate the blood brain barrier? I know highly lipid soluble drugs can, but are there any others? In addition, what is the reason for these drugs to be able to cross it? What are the implications for this? Thank you to anyone who can help. It's GREATLY appreciated.

General Properties of the BBB: -Large molecules do not pass through the BBB easily. -Low lipid (fat) soluble molecules do not penetrate into the brain. -Molecules that have a high electrical charge are slowed. There are plenty of medications that cross the BBB, and all recreational drugs do as well. The reason these drugs can cross it is because the brain has to let SOME things pass into it (glucose, oxygen, etc) but also has to keep things out (bacteria), so these are the rules it sets up to let everything the brain needs pass through, while minimizing the amount of other chemicals that can pass. The drugs that we have are just loopholes that still meet the chemical requirements.

Mesopotamians (meaning Israelites) invented beer. The Native Americans had peyote and other drugs. The Far East had the poppy seed and opium and heroine and other drugs. Are all religions the result of drug induced visions? Are there any books are anything I can read about this? Asked by slackjaw79 - Thu Dec 18 01:14:48 2008 - - 9 Answers - 0 Comments A. Entheogens are an amazingly powerful part of religion and spirituality, whether we acknowledge it much in modern times or not. "Supernatural" by Graham Hancock is an excellent book on the subject. There are plenty more. Answered by Auntie Christ stuporstar - Thu Dec 18 01:23:49 2008 why is it okay to use drugs for religious reasons? How can religion make it okay?
Q. lets say that a group uses hallucinogenic drugs for a "spiritual quest"but anyone that uses a hallucinogenic drug experiences the same thing.. Doesn't something about that just seem inherently wrong? Asked by babysnoopyfan - Sun Jan 17 22:14:54 2010 - - 8 Answers - 0 Comments A. Drugs are a problem when they fuel terrible things, and when people become so addicted that they put their lives and the people around them at risk. It's not such a big deal if it's used once or twice at a ceremony once every year and it is not abused. The problem with the illegal drugs is that they undermine the U.S. economy, fund groups with known terrorist ties, and the people who use them become so addicted that they put themselves and the people around them at risk. When you have a very carefully planned thing, with guards and such, and the people are monitored and unable to do more than take a small amount once a year or so, it's not wrong. Remember it's not the object itself that is inherently wrong, but they way the object is used… [cont.] Answered by REVA M - Wed Jan 20 04:56:20 2010 From Yahoo Answer Search: "Drugs" See also:
