User blog comment:Sanji The Cook/Closest to killing Luffy?/@comment-112.201.192.33-20120715081247/@comment-4899461-20120716142844

Yeah, but anyone could have had the antidote to Crocodile's run-of-the-mill poison. Magellan's poison that he used on Luffy is a cocktail of many different poisons, and no antidote can cure it. The BB pirates are very lucky Magellan didn't use his more powerful poisons on them. So even though they both used poisons to try and kill Luffy, the odds that Luffy survived Magellan's are significantly lower.
