Psychoactive Weeds is an Item that can be found within common locations, including choice enemy Camps, given by Spouses, and rarely as a reward from Seasonal Festivals. Upon being picked up, all future cut Weeds will drop Psychoactive Weeds Pickups. Any and all sources of cutting Weeds will create these pickups when they cut Weeds. Picking them up adds time to the duration of the Psychoactive Weeds' effect. While this is active, all Enemy bullet speeds will be decreased by a set amount and the player's movement speed will be increased by a set amount. As soon as the duration of the effect runs out both speeds will return to their normal state.
Compared to other Items, Psychoactive Weeds is one of the only ones that directly decreases Enemy bullet speeds, with the only other current option being Lard. However, unlike Psychoactive Weeds, Lard does not rely on a timer nor the collection of pickups in order to function. Instead, it will work constantly and will never be hindered by any other variables. Despite this, Lard will not provide the speed boost Psychoactive Weeds grants, perhaps making the latter superior to the former in that regard.
