depends on ones tolerance to nicotine. But nicotine metabolizes pretty quickly so more likely the last thing smoked would be having the most effect. Maybe try a weaker blend before bed time.
That’s just my “understanding.” It is still a kind of stimulant, just not one where more means more stimulation. It definitely puts me to sleep, when I get enough.
nicotine is a stimulant and depressant. It's more of an equalizer then either or. That's why it's great at helping you wake up and great at helping you fall to sleep. It's a pretty unique substance.
