I don't know if that's feasible given that adults are adults after all. But maybe just restrict the sale of cigarettes and make it so burdensome to sell them in shops so most don't even bother. And do the same for vapes. Vapes are ridiculously easy to buy so stick them in the same locked cabinet that other nicotine products go in and ban all advertising and signage.

I think that might help. Increasing friction for an activity makes it less likely to happen (like when your TV remote is in another room).

That needs a bit more differentiation, no? After all, there are vapes without nicotine. I would also differentiate between single-use vapes (just ban these, wtf) and refillables. They're also (most probably) much less unhealthy compared to smoking tobacco.
In my country (Germany), vapes are only available in shops, and most sadly only offer single-use vapes. Cigarettes were (are?) also sold in vending machines, on streets or in bars. So from my point of view, vapes are already harder to buy than cigarettes. What situation did you have in mind?
All in all, I think it would make sense to make access to these things harder / price higher based on how harmful they are, and how addictive they are.
