Best Infused Soda Variations

Not a grapefruit fan? Easily swap it for an orange. Keep the lemon the same — it balances the sweetness and gives the drink a bright, sour edge. The orange version is slightly sweeter and just as delicious. You can also skip the THC syrup entirely and use agave for a non-infused version, or blend both for a lighter THC drink recipe that suits a low-tolerance sesh. Either way, you end up with a flavourful homemade beverage that beats store-bought sodas every time.
