2 oz premium gin
4 oz quality tonic water (Fever Tree or similar)
5 drops cannabis tincture (5mg THC)
3 juniper berries
2 lime wheels
1 sprig rosemary

Fill a large Spanish copa or balloon glass with large ice cubes. Add the gin and tincture. Top with tonic water poured down a bar spoon to preserve bubbles. Drop in juniper berries, lime wheels, and a rosemary sprig. Do not stir — let the aromatics release naturally as you drink.
