  • dealer

    common informal term for someone who sells illegal drugs

  • source

    vague term that does not specify illegal activity

用法筆記

Strongly informal and associated with criminal slang. Not used in formal or academic writing. The term often implies a regular, ongoing supplier–customer relationship rather than a one-time sale.

常見錯誤

💡'connection' sounds like criminal slang; avoid using it casually about legal medication.
