Disposable vapes are a waste of materials, especially the Lithium.
They are difficult to recycle, not impossible, just difficult.
The presence as litter in the environment is extremely problematical.
And that gets worse every day that they continue to be available.
The other problematical aspect is their use to start rather than stop smoking, especially by "youngsters"
I'm not convinced banning them would work {compare prohibition in the States, or weed in the UK}
What might significantly improve the situation would be to ...
a) strictly regulate {license} their sale [and proper enforcement]
b) put a decent deposit on each one, to encourage returns. [that worked on pop bottles]
c) encourage recycling in other ways
