THC capsules are available in both full-spectrum and broad-spectrum varieties. Full-spectrum weed pills are going to contain a type of extract that has the legal amount of delta-9 THC, along with other cannabinoids and terpenes.
Broad-spectrum cannabis pills, on the other hand, are going to contain cannabinoids (both major and minor) and terpenes, but absolutely no THC. You can easily find both of these types of THC tablets on the market, you just have to pay attention to which type of extract is utilized. In this way, you can be sure that you're buying the right products.
