Table 2.

The genotypic distribution of cannabinoid receptor type 1 and 2 genes (CNR1 and CNR2) between cannabis non-users (CNU) and cannabis users (CU). The genotypes are presented as a two-level variable according to the dominant model used for the analyses. No genotype distribution differences were observed between CNU and CU groups.

Gene (Polymorphism)	Genotypes	Cannabis Non-Users (CNU)	Cannabis Users (CU)	CNU vs. CU Comparison χ2 Test, p-Value
CNR1 (rs1049353)	CC	14 (70%)	12 (60%)	0.440, 0.741
	Tcar	6 (30%)	8 (40%)
CNR2 (rs2501431)	AA	6 (30%)	9 (45%)	0.960, 0.257
	Gcar	14 (70%)	11 (55%)
