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 How can you drink alcohol and be against drugs without being a hypocrite? Q. Seriously? The same people that support drug prohibition usually have no problem picking up an alcoholic beverage. A drug is a drug, alcohol is a drug. To me, you can not use any substance and then have the nerve and turn around and tell people that they can not use another substance because you don't agree with it. Alcohol has one of the, if not the worse withdrawal for people who are addicted. It's sad really, because the intoxication level for alcohol is higher than most illegal drugs. If you don't believe me, you can look it up yourself.

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. Asked by helpplease - Wed Oct 29 14:36:06 2008 - - 6 Answers - 1 Comments A. 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. Answered by david - Thu Oct 30 21:30:40 2008 What kind of over the counter drugs could turn deadly if overdosed?

Asked by Humanitarian of the year - Sat Dec 19 18:48:37 2009 - - 2 Answers - 0 Comments A. Most otc drugs can do real harm if overdosed. Things like motrin or tylenol, I think. That's why there are warnings on the labels.
