[quote=“Murphy, post:8, topic:7303”]Slowdown can happen if your carried volume is overmax (backpack got torn up or something). Also, pain, thirst, hunger etc all decrease your speed.
taking a few perks or drinking caffeine/smoking also helps
It'd be ironic if smoking made you run faster. I don't recall it doing so, maybe indirectly as it ups your morale. It's not a stimulant.[/quote]
Smoking is a stimulant, and it does speed you up in-game (as do cigars).
Nicotine is both a stimulant and a depressant of the central nervous system and chemically is not much different than many of the other -ine chemicals (morphine, caffeine). They’re all hydrocarbon rings.
