2.5 oz vodka
0.5 oz dry vermouth
5 drops cannabis tincture (2.5–5mg THC)
Lemon twist or olive for garnish

Chill a martini glass in the freezer. Combine vodka, vermouth, and tincture in a mixing glass with plenty of ice. Stir for 30 seconds until very cold. Strain into the chilled glass. Express a lemon peel over the top and drop it in, or skewer an olive.
