Cook bacon until crisp. Drain and then coarsely crumble. Plug in an electric waffle iron to preheat. Meanwhile, combine flour, sugar, baking powder and salt in a large bowl and whisk together to blend. Pour cannabis milk in a glass measuring cup and microwave for 30 seconds at full power to heat slightly. Pour into medium bowl and whisk in melted butter and eggs. Add liquid ingredients to flour mixture, whisking just until blended. Grease waffle iron with cooking spray. Spread about 1/3 cup batter over each iron (or appropriate amount according to manufacturer's directions) and sprinkle 1/8 of bacon on top. Close waffle iron and cook until done. Repeat with remaining batter and bacon. Serve with warm syrup if desired.
