Sweet and Smoke are arguing about the gang members pushing drugs, as Sweet feels that it has never made a gang close-knit. He feels they are acting more like businessmen and only care about the money, so he asks you to go and teach them what real business is. While walking out of the house, Ryder and CJ talk about getting B Dup and Big Bear back on their side, so they head there first. Outside, you will see a short tutorial about calling Ryder back to your side, should he get too involved in a fight. This is done with the up button on the directional pad and will be useful in the long run, once you start having gang members following you.
Put that in the back of your mind for now and get in the vehicle, then drive on over to the blip on your radar. When you reach the marker, a cutscene will play out and you will have to track down a drug dealer once you regain control. He will be marked on your map with a red blip and is just a few streets over from your current location, so go ahead and drive there with Ryder. When you get there, walk up to the drug dealer, target him, then proceed to melee him until you’re finished by following the on-screen instructions. If you picked up a melee weapon earlier while exploring, then he will die a little quicker, and you are also allowed to use a gun if you have one.
Ryder recognizes the drug dealer and says his place is nearby, so it’s time to pay a little visit. He says to pick up the bat that the dealer had, but you don’t really need to do that if you have a melee weapon already. Grab your vehicle and drive to the place marked on your radar. Head inside the building to confront some Ballas, leading to a confrontation with them. Your first target should be the one with the bat, so target him and continue swinging with your weapon until he’s dead, then you can clean up the other two, if Ryder didn’t already take one of them out. You’re done here, so exit and return to your vehicle, where you simply need to go back to Sweet’s house to finish the mission.
