Item Properties

Items in the game have Properties that determine their effects in Custom Crafting, on consumption, as well as their effects when used to treat Injuries by Doctors.
Players have a value between -1000 and 1000 for each Property, with 0 being the neutral baseline. All properties will naturally drift towards 0 over time (with the exceptions of Hunger, Thirst, and Nutrition, which dift towards -1000) unless an Injury, Adaptation, or Addiction prevents them from doing so. A Positive value in a property generally does Good things, whereas a Negative value generally only does BAD things.
Properties do not have their exact values displayed, and sometimes may not be visible at all. Positive values will have a plus (+) indicator, and negative values will have a minus (-) indicator. The degree of a value may only be visible to a player with related skills. For example, all players may be able to see that Cocaine is a Stimulant, but a skilled Chemist may be able to tell at a glance the overall strength of the effects, as well as any secondary effects. Further still, a Doctor may be able to determine the negative (or positive!) health effects of consuming the drug.
Properties can be viewed by hovering your mouse pointer over the item.
