I have Psychedelicraft 1.8.0 Beta 4 for 1.21.1 on a Minecraft server, but whenever someone uses something that has visual effects, it is applied to everyone. If I do /drug username set all 0, it also removes everyone's effects. It seems like the effects are applied to everyone on the server rather than one person.

For example, if someone else on the server eats red magic mushrooms, the drug effects of red magic mushrooms are given to everyone. Even though someone else ate them, if I do /drug @s get, it shows red magic mushrooms.
