Weed affects people differently, but in game I think it should reduce nausea as well. I think it would be fun if you could get paranoid and hear noises where you don’t have line of sight.
On subject though it would be nice if there was a few options for nausea instead of just waiting it out. Bee balm and herbal teas should definitely help with nausea a bit. Bee balm already says it helps with the flu, but I’m not sure if that’s just for the aches and pains. I would like it if there were real anti-nausea meds as well, maybe make them stronger than “herbal” substitutes, similar to cough syrup in rareity.
Another idea would be something to flush you system. Kinda like how mugwort oil will get rid of parasites, but you would temporarily get sick(er) but it would rid you body quicker. Could be used for detoxing quicker or something, just a thought.
