The only time vaping causes more harm than smoking is when people use dangerous solvents (eg: not propylene glycol) or when batteries explode.
~34 million people smoke cigarettes in the US. US deaths from smoking is ~500k/yr.
Meanwhile, over 10 million vape in the US. US deaths from vaping is... only 5 people since vaping existed? And those deaths are likely from vaping juice that contains oils, rather than standard vape juice.
If you want, we can find a neutral arbiter to determine the outcome of our predictions, though they may want a percentage of the stakes.
A very small number of people are getting sick and dying because they're vaping black market THC cartridges. Most vapers are doing nicotine, and they're buying Juuls and other brand name products that are much safer than smoking.
I ask again: Are you willing to bet money that the CDC will attribute more deaths to vaping than smoking (or some similar statement that would be true if vaping was deadlier than smoking)? If you're so sure you're right, why don't you take my money?
