Does the mod work on Mac?

Yes! The mod works seamlessly on both Windows and macOS versions of The Sims 4. The installation process is identical across both platforms.

No. The mod works with just The Sims 4 base game. However, some features are enhanced by expansion packs—

City Living adds extra location-based gameplay,
Get Together improves social interactions,
Get Famous deepens reputation and fame systems related to dealing.

Can I use the mod with my existing saves?

Yes, you can safely add the mod to existing saves. Keep in mind that certain features may take a bit of time to initialize in already established neighborhoods.

Can teen Sims use drugs in the mod?

By default, only Young Adult, Adult, and Elder Sims can use drugs. However, there are optional settings that allow teen Sims to participate, which can be customized in the mod’s configuration.

Your Sim must first build relationships with existing drug users. From there, they’ll gradually gain access to supply and dealing options. Usually, starting as a casual user helps unlock social connections needed to become a dealer.

Yes, the mod provides detailed customization options. You can enable or disable specific substances, tweak gameplay intensity, or turn off features that don’t align with your preferences.

Why isn’t the mod showing up in my game?

This usually means Script Mods are disabled or the files are placed incorrectly.
✅ Make sure “Script Mods Allowed” is enabled in Game Options.
✅ Ensure the mod files are no more than one folder deep inside your Mods folder.

Will the mod cause my game to lag?

Generally, no—the mod is optimized for performance. However, spawning too many NPC dealers or events may slightly impact FPS. You can tweak population and feature settings to maintain smooth gameplay.
