"By changing the chemical structure of certain drugs, underground chemists have been able to create "designer drugs." They do this by slightly altering the chemical makeup of existing drugs with unpredictable and dangerous effects. Often the change in chemical formulation makes that drug technically not illegal, but similar in function to illegal drugs such as heroin, cocaine, opium, and hallucinogenic mushrooms. Often, designer drugs are more potent than the original substances. Some can produce more toxic effects. One example is "ecstasy," a drug in the amphetamine family. This drug produces a state of confusion, followed by a rush, then a mellow, sociable feeling. But for some, it produces hallucinations and unpredictable behavior. Designer drugs are extremely dangerous. They are variations of drugs first made in real medical labs for research purposes. Illegal drug dealers make these drugs in a makeshift lab and sell them on the streets and in schools, too. There are many types of designer drugs available. They can be stimulants, opiates, or hallucinogenics. They have nicknames such as 'china white,' 'ecstasy,' or 'rush.' They may also be identified by their chemical or trade name, such as Fentanyl or Dilaudid. There is no promise of purity with these or any street drugs. They are dangerous because harmful chemicals may be added to, or used in place of, the drug they are said to contain. The person on the street buying the drug has no way of knowing what he or she is really buying." (Retrieved online from http://www.uihealthcare.com/topics/drugabuse/drug4433.html)

Drugs that are mainly synthesized...not like a mushroom growing...you can eat the mushroom, you don't have to extract anything or change any chemical makeup of the mushroom. 2cI(supposed to be like mescaline), 2Cb is another designer. Designer drugs are potentially dangerous, as they are created by chemists with varied experience and have not been around for very long to know any long term effects of many of them. They are usually dirty with all sorts of chemicals that are potentially harmful to the body.
