What Makes Heroin So Addictive and Dangerous?

There are two main ways that heroin is metabolised; one of the ways is through the Hepatic First Pass. This is done via the removal of an acetyl group when taken orally. The other way is through injections. Heroin that is administered via this route will evade the Hepatic First Pass and will quickly cross the blood-brain barrier. This is because of the presence of an acetyl group that makes it more soluble to fat. Once, in the brain, the acetyl group is removed, and heroin is reduced to 3-monoacetylmorphine and 6-monoacetylmorphine.
