Text

Among those who had ever used cannabis, 96.7% ever smoked cigarettes and 90.6% reported smoking initiation (r=0.67). Of those who reported current cannabis use, 85% were also current tobacco users (r=0.56). CPD scores (r=0.47) and FTND (r=0.54) were also correlated with DSM-IV cannabis abuse/dependence.
