Equally, weed and dope are words that are applied to refer to the drug marijuana. When looked up in the dictionary, the name weed means any unwanted plant that is considered annoying to people, especially gardeners. The word is also employed to refer to plant cannabis. Marijuana is probably the most common drug that is used worldwide, next to prescription medications.
Dope, on the other hand, is a vernacular word that is frequently used to refer to other, more illicit drugs like heroin. There may be differences in how these words are used, but they are strongly associated. Dope, which is sometimes mentioned as heroin, is considered a pain reliever and an anti-anxiety drug.
Unfortunately, heroin is highly addictive, as most use it shoot up with a needle, and it is not safe under any circumstances. Weed, on the other hand, can either be for recreational or medicinal purposes. It is given to many cancer patients who lose their appetite. It is considered a psychoactive drug. Weed is, of course, more socially acceptable compared to heroin.
