Delta 8 and hhc carts both offer you a buzz but differ structurally. HHC is THC without any double bonds. In plain English, what that means for you is that hhc still gives users a pretty valuable psychotropic high, but one that's much milder than anything found in delta-8 thc products. So when thinking about hhc carts vs. delta 8, your hhc cartridge will have a much more mild, low-key buzz compared to anything infused with delta 8. However, each compound still has its own benefits and which one you use depends on your own personal preference.
