A drug is any substance that causes a change in an organism's physiology or psychology when consumed. Drugs are typically distinguished from food and substances that provide nutritional support. Consumption of drugs can be via inhalation, injection, smoking, ingestion, absorption via a patch on the skin, suppository, or dissolution under the tongue.
In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to treat, cure, prevent, or diagnose a disease or to promote well-being. Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis. Pharmaceutical drugs may be used for a limited duration, or on a regular basis for chronic disorders.Pharmaceutical drugs are often classified into drug classes—groups of related drugs that have similar chemical structures, the same mechanism of action (binding to the same biological target), a related mode of action, and that are used to treat the same disease. The Anatomical Therapeutic Chemical Classification System (ATC), the most widely used drug classification system, assigns drugs a unique ATC code, which is an alphanumeric code that assigns it to specific drug classes within the ATC system. Another major classification system is the Biopharmaceutics Classification System. This classifies drugs according to their solubility and permeability or absorption properties.Psychoactive drugs are chemical substances that affect the function of the central nervous system, altering perception, mood or consciousness. These drugs are divided into different groups like: stimulants, depressants, antidepressants, anxiolytics, antipsychotics, and hallucinogens. These psychoactive drugs have been proven useful in treating wide range of medical conditions including mental disorders around the world. The most widely used drugs in the world include caffeine, nicotine and alcohol, which are also considered recreational drugs, since they are used for pleasure rather than medicinal purposes. All drugs can have potential side effects. Abuse of several psychoactive drugs can cause addiction and/or physical dependence. Excessive use of stimulants can promote stimulant psychosis. Many recreational drugs are illicit and international treaties such as the Single Convention on Narcotic Drugs exist for the purpose of their prohibition.

Are there any damaging side effects to these types of drugs, such as LSD, mushrooms etc? For example with LSD assuming you get a good batch, don't mix it with anything else, and go on your trip in safe place, is there any damaging side effects long and short term.
According to the FDA, this is technically illegal, but millions of Americans do it, and some state governments, and a Senator, subsidizes this practice. The FDA and George W. Bush falsely scare us by saying the drugs may be unsafe, but Canada is a First World country and everything is safe...
I actually join an evening class to study about drugs, and today a classmate asked me to explain how our immune system reacted when we took some medicines to cure fever, for example.
You know, I am not young any more, and it is really shameful if I told that young pretty lady that I knew...
I'm not sure if this is the right forum for this but it's the closest.
I've heard about these 'smart drugs' for a while and I'm about to order a few samples of Piracetam and Lucidril and I don't think either of those (or any 'smart drugs' :smile:) are approved by the FDA.
I just quit...

How does one go about arguing against things of this nature?
For me, alcohol is a way to reach a state of euphoria and to rid myself of my psychological barriers (such as shyness). Of course, i see the problem with excessive drinking, since that could result in some sort of addiction to the...
This plain shocked me! -->This, I think, has got more to do with Politics than it does with Medicine, Bio etc<---

I accidentally posted this in the engineering thread as well (sorry mods).
I'm studying mechanical engineering (BEng) at City University, in London. I'm currently using methadone, GHB, IV cocaine, IV methamphetamine and cannabis on a regular basis (this isn't some sort of sick joke!).

Drugs are bad... M'kay?

Now, let us begin.
