>For the past 3 years I have replaced my ADHD stimulant medication with nicotine patches
My first thought was "That's a no brainer why didn't I think of that".
Then I remembered that I grew up during peak anti-smoking and so they made nicotine out to be some sort of borderline meth boogeyman rather than just extra addictive extra effective caffeine that comes in bad for your health form factors and that all that propaganda got sent straight to long term memory and I was indoctrinated by it at such a young age it didn't even occur to me to think outside the box like that.
Nicotine patches are expensive for what they are but they're basically free compared to meds.
> rather than just extra addictive extra effective caffeine
That is a severe understatement. Nicotine is consistently ranked as one of the most addictive drugs, near cocaine and heroin.
Only about 6% nicotine users manage to quit every year.

It's two very touchy subjects: nicotine and ADHD. I'm not fond to talk about it because misinformation and ignorance is just rampant. Nicotine has indeed been turned into the boogeyman.
Anyway, I told my psych about my plan, and he agreed there is research indicating nicotine works as a third-line stimulant medication for ADHD. In many modern, Western countries adult ADHD is not even recognized, let alone medicated, so one has to make do with what's available.
In my experience it is almost as effective as amphetamines, with fewer side effects, much longer lasting (a patch lasts 16+ hours), and very cheap - if you get them on ebay from China. Addiction potential is null: addiction is a function of how quickly the effect peaks, and it takes 3 hours. Not even lisdexamfetamine can compare with how unaddictive patches are.
That said, if I had access to prescription amphetamines, I'd go back to them, but I sure don't miss the days all it did was making me incredibly horny and focused scrolling social media all day long. It was a little too effective at keeping me engaged for my own good, so using a subpar medication means learning to live with ADHD, adjusting your life around your own quirk, rather than only relying on the medication to fix everything for you.
Nicotine isn't just 'extra effective caffeine.'
The research seems to indicate it's a cancer accelerant -- it doesn't cause cancer directly, but it promotes the growth and spread of existing tumors.
Studies suggest it does this through several pathways including:
(a) preventing cancer cells from self-destructing (b) making tumor cells divide more quickly (c) stimulating the growth of new blood vessels in and around tumors, helping them grow; and (d) helping cancer cells metastasize more easily by increasing mobility via epithelial-mesenchymal transition.
It also lowers the effectiveness of chemo and radiotherapy.
Admittedly, most of these are animal/lab studies, in part because it's hard to design a good study in humans since so many patients also use/used cigarettes and vapes, which confounds the results. Still, there's enough evidence out there to be cautious.
