I saw a lot of questions about the curing jars, so hopefully this video helped with that. The video comments are actually really helpful. They not only give me ideas of other how-to videos to make, but they let me know what you need help with so I can make the videos to help you. Help me help you, lol.
Video is "How To Use The Curing Jar in Sims 4 // Basemental Drug Mod" on Coffee Lover Gaming YouTube channel.
I love this mod and have been using it for a long time. The mod creator is really good at keeping the mod up to date with the game updates, so make sure you're checking that your mod is up to date. You should get a little message in the game notifications that there's a new version of the mod or that your mod is out of date.
