Facts

Heroin is addictive — its repeated abuse can lead to craving and compulsive Heroin-seeking behavior, despite severe adverse consequences.
Heroin abuse is associated with serious health conditions including HIV/AIDS and hepatitis, particularly in users who inject the drug.
The alternately awake and drowsy state that heroin users experience while taking the drug is referred to as "on the nod". Mental functioning becomes clouded.
Heroin withdrawal may occur within a few hours after the last time the drug is taken. Symptoms of withdrawal include restlessness, muscle and bone pain, insomnia, diarrhea, vomiting, cold flashes with goose bumps ("cold turkey"), and involuntary leg movements.
