Pharmaceuticals aren't really my thing. But seconding Atreus down there. The weed you get in the forest will be way stronger than anything you can find in the city, don't even bother with the city shit. Hallucinogens are big too, but again not really my thing, just hear the stories. There's a woman, Faye, who hangs around the Quills a lot. Talk to her and she'll get you set up.
