Heroin — Fast Facts (Europe/UK)
  • Derived from morphine (opium poppy), first synthesized 1874, now strictly banned across Europe, UK, and Germany.
  • Street names: smack, H, brown, white, horse, dragon, junk.
  • Sold as white/brown powder, sometimes as "black tar", or rarely as pressed tablets.
  • Main routes: injection, snorting, smoking ("chasing the dragon"). Effects: rapid, intense, short-lived.
  • Extreme overdose risk, especially from batches adulterated with fentanyl or other potent opioids (very common in UK/EU).
  • Heroin causes some of the strongest physical and psychological dependence of any drug.
  • Withdrawal is harsh, prolonged, and medically dangerous.
  • Severe criminal penalties: up to life in prison for trafficking in the UK, 15+ years in Germany, strict prosecution in all EU countries.
Heroin on Darknet Markets (Europe/UK/Germany)
  • Distribution: Most sales move to darknet markets, Telegram/Matrix vendors, and a shrinking number of street dealers.
  • Dead drops: In UK/Germany/London/Europe, heroin is usually delivered via "dead drop": payment in cryptocurrency (BTC, XMR), product hidden in a public location, buyer receives GPS/photo. No personal contact.
  • Risks: Dangerous adulterants (fentanyl/carfentanil), overdose, fake products, police stings, loss of funds.
  • Payment: Cryptocurrency (BTC, XMR) dominates. Cash drops rare in UK/EU due to surveillance.
