Effects of Heroin

Heroin is a very dangerous drug. It is harmful for our human health. It is killing us day by day. Once heroin enters the brain, it is converted to morphine and binds rapidly to opioid receptors. Abusers typically report feeling a surge of pleasurable sensation a rush. The intensity of the rush is a function of how much drug is taken and how rapidly the drug enters the brain and binds to the opioid receptors.
