Question: What is the most dangerous drug in the world

I think heroin is probably the most dangerous one. It is highly addictive, which means that one time is enough for a person to get addicted to it. As soon as it enters the brain, it is converted to morphine and binds to certain receptors we have in our brain. This causes many bad things to the body, it slows down the heart function and breathing, which can lead to a comma and permanent brain damage! People who take this drug have a lot of seizures, they get disorientated, they have abnormal behaviour, they often pass out and sometimes their whole brain stops functioning, which leads to sudden death!
