So, as the title says, I'm trying to gather some insight on specif situations of your daily life, that feel very similar to a specif drug. Ik drugs will always be much stronger but just a specif thing that reminds you of the felling that drug gives you. Here's mine:

Codeine: that warm cozy felling that you get on a raining winter night right before you fall asleep, when you stop feeling your bed.

Nitrous: when you do a set of squats till failure, get really dizzy, vision is a little blured and sound is very distorted(honestly feels incredibly similar to a low dose of nitrous).

Caffeine: when you get 8h of sleep and take a cold shower.

Weed(low dose): that moments after sunset or at 3am that dont feel real.
