Synthetic drugs are increasing in popularity in the United States. Because many people make the mistake of assuming they are safe or naturally grown, they overlook the real facts of these designer drugs. Many new versions of these drugs are manufactured in China and brought into the United States each year, and they often contain substances that have never been tested on people.
People also make the argument that synthetic drugs are safe because they are legal. In reality, states are taking action to ban certain substances found in the drugs. However, once these laws are passed, the drug designers begin to use different and equally dangerous chemicals, making it difficult for legislation to keep up.
