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 Marley smokes a lot of
bud and then get back in the studio?
David: Yea damn how was he able to pull that off?
John:
Dude, he is a functional
stoner that's why
