There is *no way* to use the stink bomb anywhere but the Detention Room.
If it is no longer in your item bag, there is no way to make another one. So your only recourse would be to restart the island. (Click the small map at upper right and then the blue button.) But actually, the game on Big Nate island is specifically written to not let you use the stink bomb in the wrong place. (Your character says "I don't want to waste it here.") It would have to be a glitch that deleted it.

If your talking about the stink bomb on big Nate island on poptropica then it goes in the detention room .To get in there you need to chew gum.
You use the stink bomb in the detention room after you deliberately go there by chewing gum. The stink bomb will scare off the teacher, and you can enter the secret room shown on the Blueprint from Nate's locker. (see related question)
The game will not let you waste the stink bomb, as the only place you can use it is in detention. Once you "use" the stink bomb, it stays right there in detention. You don't need another one. You can leave, get the blueprints, and come back. (Without the blueprint from Nate's locker, you cannot enter the secret room.) (see related questions)
