In recent years, methamphetamine use has dramatically increased in Iran while there is a crucial misunderstanding about the colloquial words related to methamphetamine among health providers, policy makers, clinicians, scholars and people in the community. The word Crystal refers to methamphetamine in some parts of Iran while in some other parts of the country, Crystal refers to a high purity street-level heroin which is called Kerack and its abuse is epidemic. Methamphetamine and heroin Kerack are different drugs in Iran. Methamphetamine is a stimulant drug while heroin Kerack is an opioid. Health providers especially clinicians and emergency medicine specialists should consider colloquial words that Iranian drug users apply. Special training courses should be designed and implemented for clinicians in Iran to inform them about methamphetamine and its frequently used colloquial words in the community. This issue has important clinical and health implications.
