Fig.2. tiff: Difference ATR-FTIR spectra of cannabis oil exposed 48 h under HPK (a), UV-C (b), and LED (c). Offset applied; values on the ordinate axis refer to the c spectrum (str. and def. Mean stretching and deformation vibration, respectively).

Fig.3.tiff: Enlargement of hydroxyl (left side) and carbonyl (right side) range of difference ATR-FTIR spectra of cannabis oil exposed 48 h under HPK (a), UV-C (b), and LED (c).

Fig.4.tiff: Comparison of the FTIR spectra of chitosan (a), chitosan with 10% cannabis oil (b), and cannabis oil alone (c) with the main absorption bands marked.

Fig.5a.tiff: FTIR changes induced in chitosan-based film enriched with cannabis oil by exposure to HPK lamp: full spectral range. The green arrows indicate the trend of changes during exposure time up to 48 h.

Fig.7a.tab: Changes in the content of methyl/methylene groups in film based on chitosan and enriched with cannabis oil sample after UV-irradiation from three different sources (calculated as relative percent changes in absorbance at 2930 cm−1). Legend: LED- LED lamp HPK - high-pressure lamp UV-C - UV lamp delta A- absorption difference

Fig.7b.tab: Changes in the content of carbonyl groups in film based on chitosan and enriched with cannabis oil sample after UV-irradiation from three different sources (calculated as relative percent changes in absorbance at 1744 cm−1. Legend: LED- LED lamp HPK - high-pressure lamp UV-C - UV lamp delta A- absorption difference

Fig.8.tiff: FTIR spectra of cross-linked (a) and uncross-linked (b) chitosan (the green arrow shows a new band resulting from cross-linking).

Fig.9.tiff: FTIR spectra of cross-linked (a) and uncross-linked (b) chitosan with 10% cannabis oil (the green arrow shows a new band resulting from crosslinking).

Fig.10.tiff: Examples of changes in FTIR spectra in cross-linked film based on chitosan enriched with cannabis oil irradiated with UV-C up to 48 h.

Fig.11.tiff: FTIR changes in the 400–1000 cm−1 range in crosslinked films based on chitosan and enriched with cannabis oil UV-irradiated under a) HPK, b) UV-C, c) LED.

Fig.12.tiff: The difference FTIR spectra of cross-linked CS + CBD oil after 48 h UV-irradiation under HPK (a), UV-C (b), and LED (c) lamp.

Fig.13a.tiff: Changes in the content of methyl/methylene groups in cross-linked the film based on chitosan and enriched with cannabis oil sample after UV-irradiation from three different sources (calculated as relative percent changes in absorbance at 2930 cm−1). Legend: LED- LED lamp HPK - high-pressure lamp UV-C - UV lamp delta A- absorption difference

Fig.13b.tiff: Changes in the content of carbonyl groups in cross-linked the film based on chitosan and enriched with cannabis oil sample after UV-irradiation from three different sources (calculated as relative percent changes in absorbance at 1744 cm−1). Legend: LED- LED lamp HPK - high-pressure lamp UV-C - UV lamp delta A- absorption difference

Fig.14.tiff: AFM images of uncross-linked chitosan containing cannabis oil before irradiation and after 48 h exposure under different lamps. Legend: Rq- root mean square roughness Ra-The average roughness
