This mod re-adds drug trafficking mini-missions that were scrapped during GTA5 development. I’ve inspired myself on GTA:Chinatown Wars drug dealing mechanics. There are multiple drug dealers found around Los Santos and Blaine County. They restock every night and their prices change. You can make a good profit by buying low and selling high.
Just approach a drug dealer and a menu should pop up. Navigate the menu using the Numpad, and select with NumPad5.
To sell drugs you have to press Right until the Sell menu pops up.
Make sure you have both the Microsoft .NET Framework 4.5 and the Microsoft Visual C++ Redistributable Package (x64) installed.
Download and install Script Hook V (including the ASI loader).
Download the latest Script Hook V .NET and copy the ASI into your game folder.
Extract the provided DrugTraffic.dll to /Grand Theft Auto V/scripts/
If that folder does not exists, make one.
