In NESARC-III, past-year DSM-IV cannabis use disorder (abuse and dependence) prevalence was 2.9%, almost twice the prevalence in NESARC-I of 1.5%41. However, these rates represented 31% of past-year users in NESARC-III and 36% of past-year users in NESARC-I. Additionally, past-year and lifetime DSM-IV cannabis dependence in NESARC-I were 0.3% and 1.3%, respectively, and lifetime cannabis use disorder was 8.5%29. These NESARC-I rates are higher than those reported in the 1991–1992 NLAES that found past-year DSM-IV cannabis use disorders was 1.2%42.
