I realize that this is hard to fathom but there are people out there masquerading as cancer patients in order to acquire prescription pain killers.
They attend support groups, ingratiate themselves with patients and/or survivors and turn on the grift.
A familiar sob story is their insurance won't pay for their prescription meds and can they buy some from you? Most people just give them the meds--free of charge.
Be careful! Some of these people are slick. One woman in my support group has even shaved her head to make her story more credible.
Another woman got taken for about $3,000 when a phony patient snatched her debit card.
