will firecrackers with skippy PB work?

hey I have a couple grams of bud and I'd like to make firecrackers with about 1.5 but I'm out of nutella and I only have skippy peanut butter left. I've heard that it doesn't work but I kind of believe it would...

Total fat 16g

saturated fat 3g

trans fat 0g

so will it work? thanks

Skippy from the US I would be careful. Salmonella ?
