In shortRegular nicotine use builds tolerance, and in smokers the extra receptors were still raised at four weeks and back to normal between six and twelve weeks. So part of your tolerance has probably gone, and a puff of a strong device now may hit harder than you remember.

What's happening in your body

Regular nicotine use builds tolerance. The receptors become less responsive, so the same dose does less, which is how someone ends up on strong salts without feeling much. In smokers, the extra receptors that come with that tolerance were still raised at four weeks and back to normal somewhere between six and twelve. So part of your tolerance has probably gone already, and more of it is going.

What to expect

This matters for one reason. A puff of a strong device now is likely to hit harder than the last one you remember. For some people that means dizziness and nausea. For others it is a stronger rush than they expected, and that is the more dangerous version, because it makes the device feel special again at exactly the wrong moment.

Try this

Open Settings, read the reasons you wrote at the start, and edit them so that they say what holds today.

What else you could do

They were written before you had been through any of this. These are the words SOS will show you on the day you need them, so it is worth having them in today's voice. If a new reason has appeared, a clearer throat, a sum of money, a person who noticed, add it while it is fresh. There is room for three, so keep the three that hit hardest.
