The Ultimate Guide to Cannabis Drinks
Discover the best cannabis drinks from top brands, learn about THC levels, and find out where to buy online.
Most cannabis sodas land between 20 and 90 calories per 12 fluid ounce can, and zero-sugar versions sit at 0 to 10. The number tracks the sweetener and the pour size, not the THC. A 5 mg or 10 mg dose of THC weighs a few hundredths of a gram, so it adds well under 1 calorie. If you are comparing a full-sugar cola, a diet-style soda, and a sparkling THC seltzer, the gap between them is almost entirely sugar.
What actually drives the calorie count
Sweetener type
Cane sugar, agave, and high-fructose corn syrup carry roughly 4 calories per gram. A 12 oz can sweetened with 30 grams of sugar reads about 120 calories on the panel. Stevia, monk fruit, erythritol, and sucralose drop that to near zero, though some sugar alcohols add a gram or two of carbohydrate per can.
Where to Buy Cannabis Drinks: Dispensary and Hemp Channels
Can size
A 7.5 oz mini can holds about 60 percent of the liquid of a 12 oz can, so the calorie figure scales down with it. A 16 oz can scales up. Always check whether the label lists calories per can or per serving, since a single can sometimes counts as two servings.
THC dose
THC, CBD, and other cannabinoids are dosed in milligrams. At those amounts the calorie contribution is negligible, which is why a 10 mg can and a 2 mg can of the same flavor often match on calories.
Full-sugar THC soda
- Pros: closest match to mainstream soda flavor and mouthfeel, widely available in 10 mg and 100 mg formats.
- Cons: 90 to 150 calories per 12 oz can, high added sugar, easy to over-consume sugar while chasing a buzz.
Use case: a single can as a dessert-style treat or a social drink when you are not watching sugar intake.
Zero-sugar or diet THC soda
- Pros: 0 to 10 calories per can, works for low-carb and diabetic-friendly routines, no sugar crash.
- Cons: artificial or sugar-alcohol aftertaste, some people report digestive discomfort from erythritol or maltitol.
Use case: daily sipping or anyone tracking calories who still wants a flavored THC drink.
Low-dose seltzer and sparkling THC water
- Pros: usually 0 to 20 calories, light carbonation, 2 mg to 5 mg doses that suit beginners.
- Cons: minimal sweetness, higher cost per milligram of THC, limited flavor range.
Use case: first-timers, daytime use, or replacing an alcoholic seltzer at a gathering.
How to read the label before you buy
- Find the Nutrition Facts panel and note the serving size and servings per container.
- Check total carbohydrates and added sugars, which signal the calorie load.
- Confirm the THC milligrams per can, not per serving, so dose and calories are compared on the same basis.
- Scan the ingredient list for sugar alcohols if you are sensitive to them.
Bottom line
Sweetener and can size decide cannabis soda calories. A regular THC cola can run 90 to 150 calories, a diet version near zero, and a seltzer under 20. The THC dose itself does not move the calorie number in any meaningful way.
