Cannabis Drink Calories and Sugar: What's in the Can

The short answer

A 12-ounce cannabis seltzer usually lands between 0 and 25 calories with 0 to 6 grams of sugar. Infused lemonades, iced teas, and mocktail-style cans run higher, often 50 to 130 calories and 12 to 30 grams of sugar. The THC itself adds almost nothing to the calorie count, even at 10 mg. What you drink around the THC is the whole story.

Why the THC isn't the calorie problem

Cannabinoids are dosed in milligrams. A 5 mg or 10 mg dose of THC is a speck of material, and your body doesn't burn it the way it burns fat or carbohydrate. Even a 100 mg package contributes a rounding error next to the liquid holding it.

So when a cannabis drink shows 90 calories, that number comes from the base recipe. The usual sources:

• Sugar and juice concentrates. Cane sugar, glucose, agave, honey, and fruit juice concentrate drive most of the count.
• Dairy. Cream, whole milk, or oat milk in coffee-style infusions adds fat and carbs.
• MCT or coconut oil. Some emulsified formulas use a gram or two of fat per serving, roughly 10 to 20 calories, and you taste it more than you count it.
• Flavor syrups. Mocktail-inspired cans lean on syrups the same way a bar does.

Typical ranges by drink type

• Sparkling water with 2 to 10 mg THC: 0 to 25 cal, 0 to 6 g sugar.
• Fruit-flavored infused seltzer: 10 to 40 cal, 2 to 10 g sugar.
• Infused lemonade or iced tea: 60 to 130 cal, 15 to 30 g sugar.
• THC coffee or latte: 100 to 250 cal, 10 to 30 g sugar depending on milk and syrup.
• Nano-emulsified shot (2 oz): usually under 15 cal, often 0 g sugar.
• Tincture added to your own mixer: effectively 0 cal from the tincture. The mixer sets the total.

What to check on the can

Not every state requires a Nutrition Facts panel on a cannabis beverage, so labels vary. When there is one, read four things.

1. Serving size. Plenty of cans hold two servings. A drink that looks like 40 calories is 80 if you finish it.
2. Total THC per container. A 10 mg can is a different product from a 100 mg can, and the calorie line stays exactly the same.
3. Added sugars versus total sugars. Juice-based drinks can show 0 g added sugar and still carry 20 g of natural sugar.
4. Sugar alcohols and allulose. Erythritol, allulose, and monk fruit keep the number low. Erythritol runs about 0.2 calories per gram, and larger amounts can upset a sensitive stomach.

Context for the sugar number

The American Heart Association suggests keeping added sugars under about 25 grams a day for women and 36 grams for men. One infused lemonade at 28 grams eats most of that. For scale, a 12-ounce regular cola sits near 39 grams of sugar and 140 calories, so a lightly sweetened cannabis seltzer is often the lighter pick of the two.

Practical picks

• Want the lowest number? Go sparkling and unflavored, or use a 2-ounce shot.
• Want flavor without the sugar? Look for stevia, monk fruit, or allulose on the ingredient list.
• Want a coffee drink? Find out whether milk and syrup are added at the counter, then you control both.
• Balancing dose and calories? A 5 mg can at 15 calories beats a 10 mg can at 120 if you plan to have two.

One timing note that affects how much you drink

Beverages hit faster than edibles, often within 15 to 30 minutes with nano-emulsified formulas and 30 to 60 minutes for standard ones, with effects lasting several hours. The calorie math connects here: people who feel nothing at 20 minutes tend to crack a second can. Give it an hour and you'll usually drink less of everything, sugar included.
