Joint

J is an abbreviation of "joint," which is a rolled marijuana cigarette. Drug users or dealers looking to get high or sell some of their "product" commonly use the abbreviation.

You might hear j in real-life conversations or see j in messages online or in texts. For example, a teenager may text his friend, "You got a j for me after school?"

While j is often used to disguise drug activity from parents or authorities, it's not very effective nowadays since it's so well known. Some other slang for marijuana includes tree, dank, mary jane, and GSW.

Example

Roll me a j, man, I'll be over in 5!
U got it, dude
