Also, John Cho’s Harold had actually given up smoking weed in A Very Harold & Kumar 3D Christmas and grown apart from Kal Penn’s Kumar before rekindling their friendship and returning to marijuana at the end of the film.
It wasn’t always so obvious that it would turn out this way for Harold and Kumar.
Whether Harold is still married to Maria and if Kumar married Vanessa is unclear, but happy endings being what they are, I’d like to think so.
John Cho didn’t speculate on their careers, but if the whole businessman thing didn’t work out for Harold and being a doctor wasn’t for Kumar, there’s a growing legal marijuana industry that they seem well suited for.
