Near the end of the Story Mission Price on Your Head, you'll see this decision branches that will give you a massive Boost to Trust points earned, depending on which leader you’ll hand the stash to. You'll have a chance to give the drug stash you recovered to either Tucker or Copeland.
Bring it to Tucker to gain more Trust points and get access to better Weapons earlier. A good Weapon is very essential to your Survival. Having access to better weapons early in the game allows you to deal with enemies more efficiently, and makes completing missions considerably easier.
Bring it to Copeland to gain more trust points and get earlier access to Bike Upgrades. If you’re using your bike often, this is for you.
The choice will entirely depend on your playstyle and priority. I personally handed the stash to Tucker so I can get access to Alkai’s wide arsenal of Weapons earlier. Besides, I’m using the Bike primarily to explore new places but after that, I’ll be primarily using the Fast-Travel option a lot.
