The 20 Most Dangerous DrugsA team of leading scientists have spent two years analysing the effects of 20 of Britain's most widely used drugs, and have devised a scientifically rigorous - and controversial - new ranking for them.

The BBC's Horizon programme has followed their research and looks at the science behind the headlines.

How do the brain and body react to each stimulant as it passes into the bloodstream, and what are the long-term effects of drugs relative to their classification?

If the current classification should be changed in view of the latest findings, what exactly is Britain's most dangerous drug?

I saw this documentary when first aired. It reported on a properly independent scientific study commissioned by the BBC.

(As I recall, it too listed Heroin as #1 — alcohol as #4 — and cannibas as #11. (Note: Also as recalled: everything after 8 or 9 didn’t really seem to matter much.)

It should be shown again and regularly.

Hemp can be used for making clothes. Do not discount the advantages of such natural gifts.
If we focused more on natural remedies the earth would not be in such a state of depletion and extinction.

I'm used to read, watch and listen lots of technical science stuff and this if this was "NAME OF SCIENCE" I quit. There was so much lag of results, given information and facts. They didn't even know how many users of some drugs have.

I have never hear about straight cannabis dead. If we get that line, we need to criminalize boring movies, becouse if you fell sleep becouse of the movie and you were cooking. Oh no.

I loved that Men Who Stare at Goats moment with the army dudes.

Read other comments below and make yourself happy that you never saw this. And remember that poisons are bad. For real xD

%100 of canabis users realize that social perceptions of it's harm are GREATLY exagerated.

This documentary undermines any semblence of credibility and is irrelevent.

I wished someone at some point during this documentary had stated the obvious...." Ironically, even after 50 years, we still really don''t know the long term effects of most of these drugs."

This 'science' has been, and continues to be co-opted by politics. There was not a single mention of percieved positive effect. These researchers should be ashamed of themselves. Pure and simple.

What a pile of horse shite.

I think that is a very good point to make that all drugs have some degree of inherent risk associated with them, some more than others. But there are also inherent dangers associated with many of our daily activities, its just that they have not been branded 'illegal' so you give it no thought; as an example every time you get behind the wheel of a car (or just in a car/bus/taxi/etc.) you run a risk (more people die in car accidents than are killed by 'illegal' drugs each year), but the risk is accepted and you use the car to get places, just like people who use drugs use them to get 'places' and people who drink use that to get 'places'.

Now if drugs were legal and regulated much of the inherent risk associated with them would be greatly reduced (i.e. impure/cut with dangerous chemicals/not the expected 'product'), its would also deal a blow to criminals who used drugs as a revenue stream and people could be properly educated regarding drugs, their usage, dangers and so on; rather than be left to find out for themselves and possibly make a life threatening decision rather than an informed one.

There is more, I could go on, but I think you can see where I stand, I just don't see how its anybody in governments business what substances I or anyone else decide to put in their body.

lies, half truths, missunformation and lies, you believe 'em all, you swallow 'em all, lies, half truths missunformation and lies, you can control heroine, the problem is culture that convinced people with this kind of sh?t that something like so isn't possible break this cycle getting informed not stoned. Pot is not at all that bad, and depending on the kind can be healthy besides vaporizators are the best and healthier way to do weed.
A date: a fruit have at least more than 200 hundred chemicals in and on it,
-How can someone be so blind? we are exposed to chemicals every minute of our lives, when driving or waiting for the bus, when out at rushhours............

How are the Drugs dangerous if they have never caused a death? Also where did they get there information because there are alot and i mean ALOT of actual published scientific documents that disprove alot of their statemants.

I actually agree on placing cannabis that high up. I myself have smoked since i was a bit over 15, and i am now 19, and have not become "a stupid stoner" yet; I do well at school, i play in a pretty groovy band, have a really cute girlfriend, and a whole lot of good friends (and no; They don't all smoke). Now, I have not f--ked up, but; They guy who introduced me and my friends to weed have f--ked up, and all of his friends with him, and at least 4 of the people that I have introduced to smoking, have really f--ked up as well. I have witnessed myself how a handful of smart and clever people, have become a bunch of idiots smoking the day away. One of them now does GHB almost every weekend, and Valium on a daily basis.

But hey, by all means, pot is great, but you gotta be careful. It's not harmless.

most of these drugs on here are listed high simply because of the effects on the body they give, getting heart attacks or similar does not count towards overdose of heroine for example, which is why all these death rates are rated low on this documentary.

also sice this documentary has been out, users and street prices have raised by a significant amount, some almost doubled.

ecstasy isn't cut with rat poison are you r*tarded? MDMA is harmless in pure form... the only reason anyone has any negative side effects from E is because of the **** people cut the MDMA with.. usually amphetamines... which in that case its the amphetamines causing harm not mdma... and marijuana is super addictive almost every swinging d*ck who tries it because a r*tarded stoner... the majority of the people responding to this video don't understand the 3 basis of the arguments for the danger of the drug...

for example, tobacco kills millions yes.. and the most... yet smoking a single cigarette is nearly harmless... you usually smoke millions of them before you actually die from them... if you did millions of lines of cocaine... you'd have died millions of lines ago... heroin is so easily overdosed on... compared to alcohol... plus you must remind yourself percentages of mortality of users vs how many use... alcohol and tobacco have way more users... if you had the same amount of users of alcohol and tobacco as you have heroin... well heroin would be number 1...

Leave it to a bunch of druggies to over analyze scientific data and get all up in arms because they show proof of negatives of their drug of choice.. or lead their misguided mind astray.

Ive never heard so much crap about drugs in my life. If anyone thinks through this information objectively, these professionals know nothing about addiction. But I am not a valid source either as I was a drug addict for many many years, yet I beleive a drug addict is a pure knowledge base of the dangers of all drugs. Heroin number 1? pfffttt... if that's true, may my tracks dissapear. Looks at Portugal, the Netherlands and see how many die in comparrison to legal drugs.

btw, because I am not from England I am amazed at the prices I was seeing. Is that right? If they are, my god you people have it cheap. Even at the exchange rate now, you pay $10 to $20 pounds for a bag of Heroin? We pay $50 for point one of a gram. Some people pay upto $1600 for 3.5 grams.

Everyone know this propaganda crap
40 thousand people die a year from alcohol more people die from alcohol than suicide all the illegal drugs put together, even the goverment actively encourage people to drink it, nice.

Tobbaco kills more than alcohol, all drugs,car crashes homicide and sucide put togther. 50% of thoes who smoke will die from its effects.

How can ectasy be safe if its been cut with rat poison ? it doesnt mention this in the documentary.

And Coulten Hansen not all Brits are stupid, So stupid we know you work at Bread Garden Market & Bakery went to Iowa City High School and it says here you like football ? Dude this is the BBC, its not the British opinion dont insult people when you have all your personal information avaiable for all to see you donut!

Having marijuana and any psychedelic on a list of dangerous drugs is laughable. One can argue that excessive recreational use is not ideal, but dangerous? Sounds like more of the idiotic propaganda that fuels the "war on drugs" in America. Don't take my word for it. Look into studies on marijuana health benefits or studies related to psychedelics.

No one here gets the point of the documentary. Marijuana might not effect everyone but it does have negative side effects. These researchers didn't look at the eye level perspective, they dug deeper to find out what can happen. Thinking of all the possibilities is how they came to their conclusions. Just because you haven't had problems with marijuana doesnt mean it can't happen. The video may not make sense to everyone but that's because we aren't scientistics who spent two years studying it. Just because it doesn't effect you, doesn't mean you can talk negatively about it.

Now newly discovered drug methodrone also called as Meow Meow has replaced XTC, Khat, Speed, Cocaine due to its high strength at dirt low price. After around 100 teenagers committed suicide due to post depression, its just got illegal in UK...yet its legal all over the world since its 2011 discovery...

When the film discusses Cannabis and its possible relation to forms of psychosis, it should have addressed the issue of whether prolonged, chronic use has any bearing on a tendency to believe in conspiracy theories or just fluffy strange things in general. This is only anecdotal of course, but just about everyone I know who is a long-term user also is a believer in the silliest conspiracy theories. It would be interesting to know if any actual studies have been done on this one aspect. To become paranoid right after getting high is well enough known. You can become privately paranoid and think that your life is disastrous; you can become socially paranoid around your friends; you can become paranoid about getting busted by the police; or you can become paranoid on a grand scale and concoct an ontological scheme about all of existence that carries over after the high is gone. How many times getting high does it take before it just sticks and you never become reasonable again? I think something like this happens when people start buying into the silliness of the David Ickes in the world or start labeling their water with good intentions.

I'm not making an argument, it's a different perspective. As far as health risks everything humans do carries health risks. It is always a trade-off. To say that weed has more health risks than let us say driving is preposterous.
Yet we don't ban driving. It's all a matter of perspective.

Considering that the psychoactive effects from solvents are most likely inseparable from nerve and organ damage and it is rated safer than cannabis makes this whole documentary a joke. I'd do heroin any day of the week before huffing.

By putting marijuana where they did and GHB as far safer just makes the whole experiment a joke. I think maybe they just want to make a point that pot isn't risk free and I agree with that but having been exposed to pot users all my life with most of the people I have known being pot smokers and having only met a few people in my life who have ever had a psychotic episode and most of them were not pot users at that time I think they have made way to much of that connection. Not to mention they forgot that the worst social problems that can be found with pot use are created by its illegality especially here in the USA.

The whole list is ridiculous. its based on biased opinion, and on the fear that media managed to create. There is a simple solution to the questions this documentary asks, and indeed many of the documentaries on this website. The solution is probably well known as "stop being stupid", and we can all do it.

Sigh...so your saying that i would be better off sniffing solvents then smoking weed and drinking? Open your god damn eyes. Also, how is ecstasy so far down the list? What about methamphetamine or caffeine? Your list is incredibly invalid because of the huge lack of scientific evidence. The only thing you guys did was complain that no research had been done on the drugs. A high school kid would have more knowledge about these drugs then you appear to have. I could rant on all day about the inaccuracies that infest this horrible documentary. "3 cigarettes and your addicted for life", i dont even need to explain that one.

If a substance could be developed that was totally non-addictive and completely harmless physiologically(or even healthful) but which allowed for expanded consciousness and subjective exploration bypassing any conceivable need for religion, such a substance would be banned immediately and cited as a Schedule A class drug, with sharp penalties for is prohibited use.

~ The above is a VERY loose paraphrasing of a statement(from memory) made a short while back by Sam Harris

This is such bullshit, for lack of a better word. How can they class the dangers of drugs especially a drug like ecstasy, without considering the psychological effects? The reason I use ecstasy as an example is because people consider to be so harmful so they're more likely to take more and more, and end up depressed, which isn't something the scientific world should overlook. Also I am someone who considers psychology and state of mind to be a huge part of addiction, therefore I find their criteria to be rather useless.

This BBC documentary is a very flawed and disappointing work. To rank cannabis above solvents and ecstasy is irresponsible claptrap. Cannabis used alone has no recorded deaths EVER! Solvents kill and brain damage thousands of children throughout Latin America and the rest of the world!
