I'm the opposite, I can't have stimulants around or I take them really frequently, I can't seem to help myself. But I can hang onto dissos are rarely use them. I got severa; grams of 4-FA the other day, I had ordered it quite some time ago. Did it the day I got it, it's not nearly as fiendy as some others but I'm gonna have to do something about that once I do my detox... maybe have a friend hang onto it.
For some reason, I have never developed a physical addiction to nicotine no matter how much I use... currently I have a high potency liquid (24mg/mL, I have also done 50mg/mL for extended periods), but all that happens if I stop is I crave it all the time, there is literally zero physical withdrawal, and in 19 years of using it on and off, I have never felt any withdrawal. No idea why that is, most people I know feel like shit when they don't have it. In my cigarette periods, I actually have felt immediately better physically when I stop. With vaping I don't feel better or worse since it doesn't have as negative an effect.
I don't experience withdrawals either, at least that I can notice, but craving something nonstop is not an experience I am ok with. Experiencing that is a huge red flag for me :/
