Still, opium is by no means as strong as the drug created by a English chemist who used opium as its raw material: heroin.
Heroin was first produced in 1874, and was given the name because it was meant to win the battle against terrible diseases – such as morphine addiction.
It affects dopamine and pain transmission in the brain, so the user feels peaceful and relaxed and feels no pain.
Alas, it quickly became clear that heroin was very, very addictive. It has been banned as a hard drug in most countries, and not for nothing.
