If you have suspicion due to symptoms that someone may be showing, then it is very likely that they are using. This may be true especially if your loved one is showing signs of depression, bizarre behavior, mood swings, lack of sleep, extended sleeping patterns, bags under the eyes, poor appearance and personal hygiene, paranoia, red dots around veins, empty bottles or containers, and loss of money.
An intervention is an attempt to stop the progressive disease of addiction when every other attempt to help has failed in getting your loved one into treatment or out of denial. In addition, an intervention is designed to free families from the grips of addiction such that they may live their own life.
