Except vape products these days aren't tobacco products. Even the ones that contain nicotine generally use a synthesized nicotine rather than nicotine extracted from tobacco.

Not saying any of this is good, but just a point of clarification. Also, for this data set I feel like it's important to distinguish between "middle schoolers" and "high schoolers." Perhaps the color keys should be used to distinguish between these categories rather than "combustible/non-combustible", because that fact is derived from the type of product which is described on the X-axis, rather than describing the data being displayed.
