The term "dope" can refer to different things depending on the context. In the past, it was used almost exclusively to refer to marijuana. However, over the past few decades, the slang word "dope" has evolved, and today it is mostly used in reference to heroin rather than weed, although it can also mean crystal meth. According to Merriam-Webster, "dope" can be an illicit drug used for its intoxicating or euphoric effects, especially marijuana, heroin, cocaine, or crystal meth. It can also refer to a preparation given to a racehorse to help or hinder its performance. In addition, "dope" can be used to describe something excellent or cool. Therefore, the meaning of "dope" depends on the context in which it is used.
