If you suspect any bad effects, call an ambulance immediately. The ambulance officers are there to help you. Be sure to describe what the person has taken. If the user is unconscious and you know first aid, place them in the come position and ensure the airway is clear. It is safer not to inject drugs.
Many users quickly become dependent on heroin.
They have a strong desire to continue to use because heroin has become important in their daily lives. If the heroin is unavailable they may panic or become anxious. Withdrawal occurs when a dependent person stops using heroin or severely cuts down the amount used. Restlessness increases, followed by yawning, a runny nose, stomach cramps, diarrhoea and a craving for the drug. The chance of death increases if the person is withdrawing from other drugs or is in poor health.
