Audrey Hope, an addictions specialist at Seasons in Malibu World Class Addiction Treatment, said if there is difficulty in stopping a drug, this should be a cause for concern. “The main sign that you are a prescription drug addict is that you use the drugs every day. You can’t function without them. You rely on them. You need them. You lie to yourself that it is for the ‘pain’ and because ‘the doctor prescribed it.’ You say it is OK to use them,” said Hope.
