Use it right now.
if squid is innocent she will use it. Simple as that, if she doesn’t she is clearly the blackened
If only one person wants me to use it, then I don’t know if it would be best to do it now, I might need to use it for later 
But hey, I’m always ready to use it
Fine, I’ll use my majestic weed powers to show you my innocence. Get ready for it, bucko

As fingers pointed to Yasuhiro about him being the blackened, Yasuhiro fell into a panic. He didn’t know what to do at all. He looked around, spotting a few people who might help him. Especially Makoto. Immediately Yasuhiro said “It wasn’t me, I swear dude!” With so much confidence and plead in his voice.
The confidence in believing Yasuhiro of being the blackened dropped to 0 along with the chances of him being the blackened. If he was such a blackened, his confidence would be non-existant. Besides, you know he’s at least 30% right in his choices to say such a thing.
Junko, the main one accusing Yasuhiro, looked angry as he saved his own life. While Yasuhiro looked on with the biggest smile.
Yasuhiro Hagakure has been revealed as not the blackened of this case! All current votes on him have been negated.
