Final answer:
Crystal, crank, and ice are all street names for methamphetamines, a highly addictive drug that can have severe long-term health effects.
Step-by-step explanation:
Crystal, crank, and ice are all street names for methamphetamines.
Methamphetamine, often referred to in its smoked form as "crystal meth," is known for its highly addictive nature and its ability to produce a rapid, euphoric high.
Unlike MDMA or cocaine, methamphetamine is made from readily available ingredients and poses severe long-term health risks such as 'meth mouth,' memory loss, and increased risk of violent behavior.
