A codename used to describe marijuana when around people you want to hide usage from (i.e. family, law enforcement).
Person 1: "Today is the worst, I can't wait to get out of work. I need to get high."

Person 2: "I have some Iranian tobacco left, I'll bring it over. We can both book a flight."

Example 2:

Person 1: "Are you alright? Your eyes are red."

Person 2: "Oh yeah I'm fine, I'm just deep in Iran."
