NRT is a scam and your addiction is the scammer. You're trying to stop poisoning yourself and you think you need a substitute for the poison! This isn't benzos we're talking about here, Nicotine has a half life of max two hours. The withdrawal is not that bad at all, it's over within four days! I just reached 87 hrs nicotine free and it was a breeze, no titration or NRT or antidepressants or anything.
JUST DO IT!!
Great question. I used both concurrently. The reason for the disposable: accessibility.
The old school vapes are just getting harder and harder to find. I had to order parts online. The juice companies were getting shut down. I didn't want to give up my addiction, and I felt so much better on vapes than i had on cigarettes, so I figured it was fine. (Nicotine alone is a bitch to your heart, though...)
I started trying out the disposables because they were readily available. I could pick one up anywhere, I didn't have to bring juice around with me, no giant batteries or kits to maintain on the go... and in exchange a much harsher hit.
this also led to me doubling my nicotine strength. I had been using 3mg juice for ovet a year by then, but all the disposables measure out to 6mg. Nothing weaker was available. had to switch to stronger stuff on the box mod.
it pisses me off how much they enshittified vaping. it was a really cool and helpful tool that got me off of tobacco. but they started targeting it at minors. instead of rich savory flavors you get all this fruity menthol crap that middle schoolers like. you get tiny vapes with flashy blinking light and fixed high potency. you get bans on it, and regulations/fees so strict that indie vape companies that started this shit for people like me now have to shut down.
oh well. it was all a facade anyway. nicotine itself is the problem. it pushes your systems into overdrive and then wears you out on seconds, until you cant even be at homeostasis without nicotine in your system. the joy of smoking is just the temporary relief of withdrawal. it's like wearing a pair of tight shoes just so you can enjoy taking them off for 5 minutes. I'm done living my life in withdrawals. so happy to be free! (and it was honestly fucking easy, you all can do it too)
