"How is this legal?" you ask.
"So glad you asked,
here's the answer:"
The 2018 Federal Farm Bill legalized hemp cultivation in the U.S. by
removing it from the Controlled Substances Act, establishing a
regulatory framework for its production, and allowing farmers to
participate in federal agricultural programs.
Key Provisions of the 2018 Farm Bill
Regarding Hemp
Impact on the Hemp
Industry
In summary, the 2018 Federal Farm Bill marked a pivotal moment for hemp in the U.S., establishing a legal and regulatory framework that has enabled the growth of the hemp industry while ensuring compliance with federal standards.
So yes, we can legally sell cannabis ("hemp") products.

3.1.1 (−)-Delta-9-trans-tetrahydrocannabinol (Δ9-THC) type
Gaoni and Mechoulam (1971) discovered the structure of Δ9-THC and explained its psychoactive properties. Rhee et al. (1997) used X-ray and proton magnetic resonance (1H NMR) studies to determine the precise conformation of Δ9-THC (Rhee et al., 1997). Dewey (1986) identified Δ9-THCA-A from Cannabis extract, which is photosensitive and cannot form crystals (structure as compound 2 shown in Table 1) (Dewey, 1986). Devane et al. (1988) discovered Δ9-THCA-B (compound 3 in Table 1) from Cannabis. Cannabis sole, a flat form of illicit Cannabis, was eluted from the silicic acid matrix using a 1:1 diethyl ether/petroleum ether solution. Δ9-THCA-B was shown to be more polar than Δ9-THCA-A in thin-layer chromatography (TLC). The determination of the crystalline structure of Δ9-THCA-B was due to the differences in biochemical properties between Δ9-THCA-B and Δ9-THCA-A (Galal et al., 2009).
Romano and Hazekamp (2019) isolated Δ9-tetrahydrocannabivarin (Δ9-THCV) using a mixture of 5 g of Cannabis and 200 mL of petroleum ether and dissolved it in 100 mL of absolute ethyl alcohol (EtOH) (Romano and Hazekamp, 2019). Spectroscopic evidence for Δ9-trans-tetrahydrocannabidiolic acid (Δ9-THCVA) was reported by Matsuda et al. (1990), followed by mass spectrometric evidence data (Pate, 1994). The analysis of 51 samples sourced from various geographic regions led to research on the C3 homologs of Cannabis (Turner et al., 1973). Balcke et al. (2014) discovered a new homologue of Δ9-THC with a methyl side chain, 9-tetrahydrocannabiorcol (Δ9-THC-C1), in an extract of Brazilian Cannabis (Balcke et al., 2014). The concentration of Δ9-THC-C1 was low, so it was not expected to have a significant impact on the drug’s biological action. Dewey (1986) identified Δ9-trans-THCA-C4 and Δ9-trans-THC-C4 using GC-MS, as well as Δ9-trans-tetrahydrocannabiorcolic acid (Δ9-THCA-C1) (Balcke et al., 2014). Several techniques, including NMR spectroscopy and Gas Chromatography-Mass Spectrometry (GC-MS), were used to identify monoterpene or sesquiterpene esters of 9-tetrahydrocannabinolic acid A in Cannabis sativa L. These esters were found to be precursors to Δ9-THC and were broken down into their constituents when subjected to high temperatures during GC-MS analysis (Caspi et al., 2005). Chromatographic methods, such as vacuum liquid chromatography (VLC), High-performance liquid chromatography (HPLC), and Supercritical fluid chromatography (SPC) were used to isolate these cannabinoid esters from high-potency C. sativa varieties. Cannabisol, a dimeric cannabinoid, was also isolated using flash silica gel column chromatography from Cannabis samples that contained a significant amount of CBG (Costa et al., 2007).
