dependence

uncomfortable or life-threatening effects that may be experienced during withdrawal.
c. Larger amounts of substance taken over more time than intended.
d. Unsuccessful efforts or a persistent desire to decrease or control the substance use.
e. Much time is spent in obtaining the substance, using it, or recovering from its
effects.
f. Important work, social, or recreational activities are given up as a result of the
substance.
g. Despite knowledge of recurrent or ongoing physical or psychological problems
caused or exacerbated by the substance, substance use continues.
