Table 2 Mean (standard error) daily opioid consumption and daily pain numeric rating scale (NRS) scores, by marijuana status and other drug use

From: The grass is not always greener: a multi-institutional pilot study of marijuana use and acute pain management following traumatic injury

Outcome, stratified Marijuana user (n = 54) No marijuana use (n = 207) p value
No other drug usea (n = 40) (n = 198)  
 Mean opioid consumption 8.53 (0.33) 5.86 (0.18) <  0.001
 LSMb opioid consumption 7.57 (0.36) 5.65 (0.18) <  0.001
 Mean pain NRS score 5.17 (0.15) 4.17 (0.07) <  0.001
 LSMb mean pain NRS score 4.92 (0.16) 4.19 (0.11) <  0.001
Other drug usea (n = 14) (n = 9)  
 Mean opioid consumption 8.81 (0.82) 10.58 (0.97) 0.29
 LSMb opioid consumption 5.59 (0.81) 6.10 (1.17) 0.71
 Mean pain NRS score 5.02 (0.24) 5.54 (0.25) 0.15
 LSMb mean pain NRS score 5.28 (0.34) 6.00 (0.48) 0.07
