A person who gets stoned with a certain amount of
bud but however, he or she is still at their full capacity to do certain tasks without an issue. A functional
stoner can go to work or a public place and act completely
normal as if they're not stoned.
John: You seen the video where Bob

David: Yea

John: Dude, he is a functional
stoner that's why
