First Dose 4 - Uncontrolled Substance

Shane Williams

This page is a walkthrough for the Los Santos Drug Wars DLC mission, Uncontrolled Substance. It’ll navigate you through the necessary steps to getting through the trip.

You seem to have consumed too much acid.

Newsflash, FYI. You’re one of us now. It’s time you became a certified, bona fide Foligan. Get down here for your initiation.

How To Start and Complete Uncontrolled Substance

In order to start the Uncontrolled Substance Mission which is the fourth mission in the First Dose portion of the Los Santos Drug Wars DLC you’ll need to complete: First Dose 1 - Welcome to the Troupe, First Dose 2 - Designated Driver and First Dose 3 - Fatal Incursion. Once you’ve completed them, drive over to the Abandoned Warehouse (The Freakshop) and you’ll see a yellow circle. Enter it and press up on the D-Pad to begin!

Follow Dax

How To Survive The Trip

Once you regain control of your character you’ll find yourself on a peddle bike. Follow Dax down into the Storm Drain, then eventually you’ll notice trucks falling from the sky and heading in your direction. Here you’ll want to look for where the trucks are positioned and move into the area where there’s a space. However, the positions will constantly be changing, so you need to pay close attention.

After you’ve gone through the Gateway you’ll now find yourself on a Motorcycle in the sky. There’s no obstacles here, so just drive straight until you pass the next gateway. Next up, you’ll be placed on the path to Kifflom, so continue driving straight ahead whilst adjusting your speed to allow you get through the gates before they close. In the next area you’ll notice that large blocks are coming towards you, so just move to the left or right depending on where they are to avoid them.

(1 of 5) Move into a space to avoid the Trucks.

Upon passing the Gateway you’ll be warped into a Go Kart. Simply race down the Rabbit Hole, then eventually the controls will become reversed, so you’ll need to press LT or L2 to go forwards and left on the analog stick to right and right to go left… confusing i know.. Following this you’ll be back on land chasing a rabbit, but don’t worry about shooting it and just run for the gateway. Finally, you’ll find yourself free falling, so just position yourself so you fall through the circles and land in the water to complete the mission.
