The purple haze drink is primarily known as a cocktail, but you can perfectly make it a shooter instead. For that, just use the same ingredients of the above variants and use obviously less juice/soda as a filler. You can replace the vodka with Jack Daniels, and make it 1 measure Vodka, 1 measure blue Curacao & a splash of cranberry juice. Please note that the Whisky will make the shot have a strong flavor, stronger than if you're using Vodka.
