Pot. Grass. Weed. Wikipedia lists 1,200 slang names for cannabis alone, with many more expressions to describe marijuana quality, its effects and the people who smoke it.
The long history of prohibition gave rise to the many slang terms, letting cannabis users talk amongst themselves and avoid alerting the law. Slang changes and evolves. As authorities become wise to what one word means, that’s a signal to change the language. And of course coming up with slang names is just fun.
Wikipedia notes that many slang words for cannabis date to the jazz era of the 1920s, when it was called weed, reefer, gauge and jive. New slang names, like trees, came into use in the early 2000s. When Canada legalized cannabis, the Canadian government tried to help consumers by publishing a list of weed slang, since removed from the government website but immortalized by Buzzfeed. Included are obscure words like errl and purp, which must be popular with the stoners in the federal bureaucracy.
