Methedrines are a class of synthetic stimulants that have gained popularity among drug users because of their potent effects on the central nervous system. They are often referred to as "party drugs" because they induce a feeling of euphoria and heightened energy that can last for several hours. Synonyms for methedrines include methamphetamine, crystal meth, ice, speed, and crank. These terms are often used interchangeably, but they may have slightly different effects on the body and could be associated with different levels of purity or quality. Regardless of the name, methedrines have serious side effects and can be highly addictive, leading to long-term health complications and even death.
