Dumpweed

Dumpweed is a slang term, primarily used online, to refer to marijuana of perceived low quality. The implication is that the cannabis is so poor that it is akin to "dumping" it – discarding it as undesirable. The term carries connotations of weakness, unpleasant taste, and/or ineffective psychoactive effects. The origin of the word likely stems from a combination of "dump," signifying discarded waste, and "weed," a common slang term for marijuana. The term is often used disparagingly.
