According to the chart,
Hershey’s Special Dark Chocolate Bar 1 bar, 1.4 oz. 25mg of caffeine
According to this source, a Hershey’s kiss ways approximately 0.2 ounces. So, it’s equivalent to 1/7 of the weight of a Special Dark chocolate bar, meaning approximately 3.6mg of caffeine for each dark chocolate Hershey’s kiss. I’m not so sure I should have done the math on dark chocolate…
I would assume so, but I didn’t want to be make an 
of myself.
