We have received complaints about a growing number of fraudulent websites masquerading as Addiction Therapy-2020 or Scientificfederation and offering registration, hotel bookings and other arrangements for the upcoming Addiction Therapy-2020 or Scientificfederation. Many of these sites charge significant commissions. We are also aware of some companies cold calling Congress delegates, using data which has not been provided by Addiction Therapy-2020 or Scientificfederation.
