What are THC Bath Bombs?
A THC bath bomb is the same thing as a normal bath bomb, but it has THC in it. THC bath bombs are spheres of compacted ingredients, including essential oils, extracts, and of course, cannabinoids, that dissolve when they are dropped into your bathwater. As they dissolve, they release their scent and cannabinoids, and sometimes turn your bathwater a particular color. Bath bombs are designed to create a spa-like, luxurious bath and when cannabinoids are added to that mixture, it only enhances the experience.
How Do THC Bath Bombs Work?
THC bath bombs use the same science as a cannabis topical.1 Your endocannabinoid system consists of an intricate network of receptors that are activated both by our body’s own endocannabinoids and by the marijuana plant’s phytocannabinoids.
When you submerge your body into water enhanced by a THC bath bomb, you’re coating the receptors in your skin with the cannabinoids inside the bath bomb.1 While this will likely not cause any psychoactive effect, it may cause a feeling of intense relaxation.2 This “body high,” as it is sometimes called, can be different for everyone, but what’s not relaxing about a hot bath?2
Remember, depending on the potency of your cannabis bath bomb, it’s possible that some THC can make it through the thinner skin on your body and into the bloodstream. However, it will never be with the same potency as vaping or smoking marijuana.3
How Do I Make My Own DIY THC Bath Bomb?
So you’re ready to soothe your senses, but you want to make it your own personal experience—not just buy a bath bomb off the shelf. We get it. Fortunately, it’s pretty easy to DIY THC bath bombs at home, provided you have the right ingredients and tools to make it.
A note: You don’t have to buy your own cannabinoid oil. You can make it yourself using our cannabis coconut oil recipe. Of course, if you’re more interested in creating your bath bomb than you are in the process of making cannabis oil, just head to the dispensary and pick some up.
THC Bath Bomb Ingredients
- Bath bomb mold
- 1 tbsp THC-infused coconut oil or canna-oil
- 1 cup baking soda
- ½ cup Epsom salts
- ½ cup cornstarch
- 1 tsp water
- Favorite essential oils
DIY THC Bath Bomb Directions [3 Steps]
Step 1: Combine Bath Bomb Ingredients
In a bowl, combine all the dry ingredients in the list together. Once mixed, add the THC or CBD oil (or full spectrum cannabinoid oil), your coconut or olive oil, any essential oils, and a splash of water as needed. Your goal is to get the mixture wet enough that it sticks together in a ball. It shouldn’t be mushy, and it shouldn’t crumble when you touch it.
Step 2: Mix Until Firm
Once you have the right consistency, keep mixing. All the ingredients should start to stick together and form a very loose ball (or blob). Now, grab your bath bomb mold or even a cookie cutter will do the trick.
Step 3: Use Bath Bomb Mold
Pack your bath bomb ingredients into the mold and close it up. Now, press the two halves together firmly. When you open the mold, you should have a fully formed sphere. If your bath bomb crumbles, or if it refuses to hold its shape, your mixture needs to be moistened or dried, respectively.
It’s really that easy. Just remember, if you make a bunch of THC bath bombs ahead of time, you need to store them in an airtight container away from heat and light. This will help preserve the cannabinoids in your bath bomb.
Answering THC Bath Bomb FAQs
We love getting crafty with cannabis, and we want you to feel the same way. Here’s a few answers to questions that may help you better understand THC bath bombs:
Do THC bath bombs get you “high”?
Unlikely. It’s very hard for THC to pass through the skin and into the bloodstream. Because of this, you are unlikely to experience any psychoactive effects from your THC bath bomb. While potency, the thickness of your skin, and other factors can be contributors in this, you will never experience the same effects from a cannabis bath bomb that you would from consuming cannabinoids.3
How do I use a THC bath bomb?
Using a THC bath bomb is easy. Fill your tub with your preferred temperature of hot water. Once the tub is full, drop your THC bath bomb into the water. It should immediately start to dissolve.
Do THC bath bombs work?
There is evidence to support that cannabis topicals have an effect on the skin,3 so it stands to reason that THC bath bombs can provide similar benefits. Plus, there are a lot of great ingredients, outside of cannabinoids, that go into THC bath bombs, including Epsom salt, essential oils, and more.
All About THC Bath Bombs
The best part about THC bath bombs is that you have options. You can purchase them off the shelf from your local dispensary, buy the ingredients and make them at home from scratch, or buy a combination of pre-made ingredients and your preferred additions to make your own custom bath bomb. You’re only limited by your creativity and no matter what, you’re rewarded with a relaxing bath—what’s not to love about that?
