Drug mod was something I made when I was like, 15. It let you grow pot and opium and then harvest it, then sell it on street corners for profit. If any cops found the stash, they could baton them to set the bricks on fire and give the owner massive demerits.
Now Jasa made it so you can buy weed from TV monitors randomly placed on the map, and when used, makes your screen blink different colors.
