  • Withdrawal, which is defined as either physical or psychological signs or symptoms consistent with withdrawal from a specific drug, or taking that drug or one chemically close to that drug in order to avoid developing symptoms of withdrawal
  • Larger amounts of the drug are taken or for longer than intended.
  • The person has a persistent urge to take the drug or has unsuccessfully tried to decrease or control the drug use
  • Excessive amounts of time are spent either getting, using, or recovering from the effects of the drug
