In a large mixing bowl, combine the bread flour and water. Mix until a shaggy dough forms. Cover with plastic wrap and let rest for 1 hour (autolyse).
Add the sourdough starter, salt, and cannabis-infused olive oil to the dough. Mix until fully incorporated. The dough will be sticky.
Turn the dough out onto a lightly floured surface. Knead for about 10 minutes, or until the dough becomes smooth and elastic.
Place the dough in a clean bowl, cover with a damp towel or plastic wrap, and let it rise at room temperature for about 4-6 hours, or until doubled in size.
Turn the dough out onto a lightly floured surface. Gently shape it into a round or oval loaf. Place the shaped dough onto a piece of parchment paper.
Cover the dough with a damp towel or plastic wrap and let it rise for another 2-4 hours, or until it has puffed up.
Preheat your oven to 475°F (245°C) with a Dutch oven or baking stone inside.
Use a razor blade or sharp knife to make a few slashes on the top of the dough. This allows steam to escape and helps the bread expand in the oven.
Carefully transfer the dough (with the parchment paper) into the preheated Dutch oven or onto the baking stone. Cover with the lid (if using a Dutch oven) and bake for 20 minutes. Remove the lid and bake for another 20 minutes, or until the crust is golden brown and the loaf sounds hollow when tapped.
Transfer the bread to a cooling rack and let it cool completely before slicing.
