Before anyone starts, hear me out -

My mum has given up smoking after 50 years, but cannot cope without nicotine. Nothing works. Except vapes. She can't be doing with all the fucking about with liquids and coils, and recharging, so the disposable ones are great, perfect.

But, I want to buy a load in one go online. They should be totally automatic (not even needing to press a button) and have a high nicotine level. We're talking a 60 a day smoker here.

To address the obvious points -

1. I know vaping "might be bad" but there's no evidence yet. Yes, I know "but we said that about cigs!" - we didn't . It was known smoking killed people for centuries. It just so happened that marketing came along about the same time as modern medicine so big tobacco suppressed studies for decades. That doesn't happen nowadays - yes we don't know for certain vapes are safe, but largely because they haven't been around for 50 years yet. We do know they're much better than smoking 60 a day.
2. Yes, disposable ones are bad for the environment because fuckwits chuck them on the floor. All used ones will go in a box and I'll take them to the recycling centre where there is a dedicated li-ion battery bin. I'm quite a staunch environmentalist.
3. For what it's worth, I think they should be banned for sale and prescribed solely on the NHS for long term smokers as a quitting tool. For many people, like my mum, they're the only thing that works.
