In general, most Doritos products have a Scoville scale rating of between 0 and 100,000. However, the Doritos Roulette product has a rating of 1.5 million. This means that it has 5 times the Scoville heat of a regular Doritos product.
Consequently, eating a single Doritos Roulette chip could result in extreme heat sensations in the mouth and stomach. As such, even small amounts of this product should be avoided by those with severe heat sensitivity issues.
