When combining THC and CBD you are getting the "Entourage effect" or as we like to call it "More bang for your buck" as THC encourages your body's endocababinoid system to uptake the potent effects of CBD allowing the user to get the most from it.
 
Marijuana Bath Bombs vs. CBD Bath Bombs 
A frequently asked question about it is “do CBD bath bombs contain marijuana?” The answer to this question is that it depends. CBD is present in all cannabis plants, including both hemp plants and marijuana plants. So, some of them could contain CBD from hemp plants. While others could contain CBD from marijuana plants. Whether or not a specific CBD product (such as a bath bomb, a CBD oil, a CBD tincture, or a CBD edible) contains marijuana depends on the source of its CBD.
When people ask whether or not there’s marijuana in it. They’re usually also wondering whether or not there’s any THC. Hemp-derived CBD bath bombs will contain little to no THC. Hemp plants contain a maximum THC percentage of 0.3%, which is a tiny, trace amount that won’t cause any psychoactive effects. Marijuana-derived CBD bath bombs, on the other hand, could potentially contain quite a bit of THC. Depending on the blend within a specific marijuana bath bomb, it could contain absolutely no THC or it could contain a substantial amount.
It’s important to note that while a marijuana-derived CBD bath bomb could contain THC, that THC is unlikely to cause psychoactive effects. It’s more likely to just provide other benefits, like pain relief. That’s because when you use topical cannabis products, like cannabis bath bombs, your body absorbs the cannabinoids in that product into your skin, where they work locally. In general, the cannabinoid THC can’t breach the bloodstream when applied topically. There are some exceptions to this rule, such as transdermal patches, which are designed to get into your bloodstream. Additionally, some THC bath bombs may come with warnings saying that they could possibly cause mild psychoactive effects in women. But, typically, topical cannabis products that contain THC won’t cause psychoactive effects in the same way other cannabis products that contain THC would.
