Does Weed Have Calories? The Complete Answer for Every Method
Smoking weed: zero calories. Edibles: 10-200 calories. Get exact numbers for every cannabis format, plus why your fitness tracker lies after THC.
Written by Sipho Sam
September 24th, 2025
Here's the immediate answer you need: smoking and vaping cannabis add zero dietary calories to your day, while edibles contain calories from their food ingredients (sugar, butter, flour), not from the THC itself.
If you're tracking calories, maintaining a fast, or managing your macros, you can keep using cannabis without mysterious numbers ruining your progress.
Calories only count when something enters your digestive system and gets processed as food energy.
When you smoke or vape, the plant material combusts or vaporizes before it ever reaches your stomach.
Whether you choose from Mood's precisely labeled gummies, which are 10 calories each, or their zero-calorie smokable options, you'll finally have real numbers to work with.

Why Smoking and Vaping Add Zero Calories to Your Diet
When you smoke or vape cannabis, combustion destroys the plant matter before it can become dietary energy.
Raw cannabis flower contains about 3-4 calories per gram from plant fiber, but those calories literally go up in smoke and never make it to your digestive system.
The cannabinoids like THC that create effects are molecules small enough to pass through your lungs into your bloodstream, but they're not food energy your body can use as calories.
Mood's extensive line of over 100 smokable products — from THCa flowers to disposable vapes — can be enjoyed without impacting your calorie counting.

The Simple Rule That Governs All Cannabis Calories
Here's the master principle that clears up every cannabis calorie question: if it doesn't reach your stomach, it doesn't count as dietary calories.
This single rule explains why smoking is zero calories while brownies are 200 – it's not about the cannabis, it's about the route it takes into your body.
Anything you inhale (smoke, vapor) bypasses your digestive system entirely, resulting in zero dietary calories, while anything you swallow (edibles, drinks, oils) gets processed like food and contains whatever calories are in the carrier ingredients.
Once you understand this foundation, you can confidently log your cannabis consumption just like any other part of your diet.
What You're Actually Counting in Edibles
THC contains no meaningful calories – the butter, sugar, flour, and chocolate in edibles show up on your tracker.
When Mood's 15mg Delta-9 gummies are listed at 10 calories, those calories come entirely from the corn syrup and sugar used to make the gummies, not from the 15mg of THC.
A 5mg gummy and a 25mg gummy made with the same recipe will have identical calories because the psychoactive strength changes, but the food energy doesn't.
Mood makes this transparent by posting complete nutrition information and third-party lab results for every product, so you know exactly what you're consuming.

Real Cannabis Calorie Counts You Can Log Today
Here are the actual calorie ranges for everyday cannabis products you can enter into MyFitnessPal.
THC gummies typically contain 10-30 calories per piece, with Mood's 15mg Delta-9 gummies containing just 10 calories each. Simply check the label for the per-piece count.
Cannabis brownies pack 150-200 calories per serving, the same as a regular brownie, since the THC adds no extra calories.
THC chocolates range from 50-100 calories per piece, similar to regular chocolate bars of the same size.
THC seltzers can be completely calorie-free, like Mood's Strawberry Lemonade seltzer with zero calories, perfect for strict calorie tracking.
THC sodas contain 25-30 calories per can, such as Mood's Cherry Lime soda, so check the nutrition label for exact counts.
All flowers and pre-rolls contain zero dietary calories because you're smoking them, not eating them — don't log them.
Vape cartridges also deliver zero calories regardless of strain or strength – skip logging these entirely.
If you eat half a gummy, you get half the calories and half the THC, making portion control predictable for both tolerance and calorie goals.
The Hidden Calories in Tinctures and Oils
Oil-based tinctures contain approximately 8-10 calories per dropper from the carrier oil (usually MCT or olive oil), which most guides overlook entirely.
These liquid calories are easy to miss because tinctures feel medicinal rather than food-like, but your body processes that oil like any other fat.
The cannabinoids dissolved in the oil don't add calories – it's purely the carrier oil contributing those 8-10 calories per dropper.
Mood's capsules, which use MCT oil, provide precise amounts with predictable calorie content that is easy to account for.
Will Cannabis Break Your Fast?
Smoking and vaping cannabis will not break your fast because no calories enter your digestive system.
The cannabinoids absorbed through your lungs don't trigger the metabolic processes that end a fasted state so that you can take that evening hit without worrying about tomorrow's fasting window.
Edibles and oil-based tinctures will break your fast since they contain actual food energy that your digestive system processes.
Even Mood's low-calorie 10-calorie gummies technically end your fast, though some intermittent fasting protocols allow up to 50 calories.
For those who want effects during fasting hours, Mood's zero-calorie seltzers offer a perfect solution – you get the THC without any calories, keeping your fast intact.
Why Your Fitness Tracker Shows Extra Calories After Cannabis
That jump in "calories burned" on your Garmin or Apple Watch after using cannabis isn't real metabolic burn – it's your device misinterpreting an elevated heart rate.
THC can temporarily increase your heart rate, making your tracker think you're exercising when you're actually on the couch.
These phantom calories don't offset what you eat in edibles — if you consume a 150-calorie brownie and your watch says you "burned" an extra 100 calories, you still consume 150 real calories.
The elevated heart rate from THC doesn't create the same metabolic demands as actual exercise.
Track what goes in your mouth, not what your wrist says after cannabis use.
Managing Appetite Changes Without Derailing Your Diet
Increased appetite after cannabis is real – THC stimulates ghrelin production and enhances food's sensory appeal.
The key is planning rather than finding yourself in the kitchen at midnight without a strategy.
Pre-portion healthy snacks before your session and brush your teeth immediately to reduce snacking urges.
Consider fast-acting formats like Mood's nano gummies, which hit in 5-15 minutes. This shorter onset time lets you gauge effects before appetite kicks in.
Choose your timing strategically by using appetite-enhancing products when a meal is planned, turning enhanced food enjoyment into a feature rather than a diet challenge.
Choosing Cannabis Products Based on Your Calorie Goals
Your dietary priorities should guide your cannabis choices – strict calorie counters and keto dieters thrive with Mood's extensive zero-calorie options, including all flower, pre-rolls, and vapes.
These formats deliver full effects without any dietary impact, perfect for maintaining strict macro targets.
For moderate trackers who can spare 10-30 calories, Mood's precisely portioned gummies offer convenience with transparent labeling and clear nutrition facts.
The beauty of Mood's range is the flexibility to switch between formats based on your daily goals – grab a vape on tight calorie days, enjoy a gummy when you have room in your macros.
Their 100-day satisfaction guarantee lets you experiment with different formats until you find what works for your lifestyle.
