World’s Top 10 Most Dangerous Drugs


According to a study published in The Lancet, alcohol and tobacco rank among the ten most dangerous substances used by humans. Both alcohol and tobacco have been assessed to be more dangerous than illegal drugs like marijuana or ecstasy.

The following three factors were considered in ranking the harmfulness of each drug that was evaluated:

  • Physical harm to the user
  • Addictive potential of the drug
  • The drug’s overall impact on society


Psychiatrists who specialize in treating addictive behavior and legal or police officials with scientific or medical expertise were asked to assign a score to each of the three factors listed above for each drug that was evaluated in this study. All told, 20 different drugs were evaluated, including cocaine, heroin, ecstasy, amphetamines, and LSD.

Ranked from most to least dangerous, the ten most dangerous substances were deemed to be:

(1) Heroin – popular street names include smack, skag, and junk. Street price is between £10-20/bag, 300,000 UK users and kills 700 people a year in the UK.

(3) Barbiturates – Popular slang names include yellow jackets, reds, blues, Amy’s, and rainbows. Street price is £1-2/tablet and they kill 20 a year in the UK.


(4) Street Methadone – Street price is about £10/100ml, there are about 33,000 illegal UK users and 295 a year die.

The remaining drugs that were assessed in this study ranked as follows:

  1. Cannabis – includes marijuana.
  2. Solvents – volatile substances that can be inhaled, such as glue, nail polish remover, paints, hair spray, and lighter fuel (gas).
  3. 4-MTA – is a derivative of amphetamine and has similar effects to ecstasy.

  10. Khat – an amphetamine-like stimulant.


It is estimated that tobacco causes 40 percent of all hospital illnesses, while alcohol is involved in more than 50 percent of all visits to hospital emergency rooms. In light of these statistics, the authors of this study question why alcohol and tobacco are legal to use within current drug policies for Britain and the United States, while less harmful drugs like ecstasy and LSD are deemed illegal to use.

The bottom line: alcohol and tobacco are two of the most dangerous substances that you can expose yourself to on a regular basis. In terms of overall potential to cause harm, if used regularly, alcohol and tobacco belong in the same category as other recreational drugs like cocaine and heroin.
