Top 10 Least Harmful Illegal Drugs

There's lists about the worst drugs in existence. But how about a list of measuring which illegal drugs are actually not that unsafe. Criteria of safe would include: low addiction potential, low toxicity, low lethality and lack of judgment impairment.
The Top Ten
1 Marijuana

People on this thread are really ignorant and are going with their personal prejudices over science and logic. Basically, according to them, marijuana is safe, alcohol is safe-ish and literally everything else is horrible. That's not how it works. Marijuana has zero lethality, but it has addiction potential which tryptamines like LSD and Shrooms have been proven not to. While alcohol is safe to most individual users, it causes societal harm on a level that no other other drug does. None of these drugs come close to causing the amount of violent aggression that an alcoholic is capable of.

As a user of cannabis, I've had virtually no negative experiences from either a mental standpoint or a health standpoint. What a lot of people don't get about cannabis is that it doesn't fit into any other drug classification. Cannabis is it's own entity because it affects the user based on the user's own personality, as it interacts with naturally occurring cannabanoids inside your own brain. All of the lies spreading around from the prohibitionist crowd are not believed anymore because more people have had experience with this drug than any other drug besides alcohol. Legalize it!

I've done weed before and as a guy who has experience. It is actually safer than it looks. It's safer than tobacco and alcohol which means it cigarettes will damage your lungs more than weed does. My dad and grandparents smoke and offered me weed before. I tried them and thought "damn smooth".

It's even safer than medicine and it won't give you lung cancer until you smoke 654324 times a day. I wouldn't mind trying another joint of weed but it's best to not be addicted.

Easily the least harmfull drug out there. There are no reported overdoses of marijuana. We are not quite sure how much weed it takes to kill someone but it is said to take between 20,000 - 40,000 joints and you have to smoke them in under an hour. This fact is not 100% different sources have different answers but it's not an easy task to overdose on marijuana. You pretty much have to try to overdose and even if you try it's still quite hard. You don't get violent like some people get with alcohol wich means that weed assualts usally does'nt happen, LEGALIZE IT ALREADY!


Even weed has the aspect of psychological addiction, and inhaling any kind of smoke isn't good. Still would be one of the safest drugs ever, if it weren't for psychedelics. LSD is definitely the safest drug you can get a hold of, because not only is the dosage low, but the substance itself doesn't 0 damage to your body physically and mentally. Additionally there have been studies that show LSD improves peoples' mindsets and positively changes their perception in the way that they find different ways to solve problems, have more objective unbiased views of the world, and appreciate the little things in life a little more.

I have taken many LSD trips in the sixties ( pure medical LSD of the Sandoz factory. This was a legal drug till 1967 ). Never had a problem but I've seen with the same pure LSD substance many LSD casualties on other people. Also, just think about the famous acid casualties of the sixties ; Syd Barrett of " Pink Floyd ", Rocky Erickson of the " 13th floor elevators " etc... Maybe not so " not harmful " as many people think. A drug should be called " safe " if everybody has the same benefit and the same adverse effects of the drug. The effects of LSD are different for every individual person. Can you call this really " safe " if every person reacts and responses differently with the same substance? Safe for many but also unsafe for many others.

LSD is actually a bit more extreme than most hallucinogens, but it's still safer than alcohol and even cannabis. If you use it too often however, you'll go the way of Syd Barrett from Pink Floyd.

Almost impossible to overdose on and can provide extremely meaningful experiences. It's not physically bad for you and not addictive at all. This truly is one of the best and safest drugs on the planet.

3 Psilocybin (Mushrooms) & DMT

Shrooms are the only thing on this list that will, with a 99% chance, not make you feel worse the next day. Actually since its quite effective against depression, you'll most likely feel a lot better for quite some time.
No overdose, no addiction, no toxicity, no cancer, no lowered testosterone etc etc
Easily better than weed, which causes long term learning deficits, is bad for your immune system, lowers physical performance...

Dmt is already apart of our biochemistry, it's completely safe and evidence has even shown that use can help empathy, creativity and intelligence. Studies will be done on its long term benefits since to my knowledge we are only at the hypothetical stages of dmt. It's unfortunate it's illegal since it's a chemical found in our brain that can't be studied unless you are FDA approve due to its short but powerful visions.

Psilocybin has been ranked less dangerous than pretty much every other drug (including weed) by actual researchers on more than one list. They've also been shown to have lasting positive effects on creativity and aesthetic appreciation. They're physically less dangerous than caffeine, which is legal for children to buy.

100% non addictive, non toxic, and have zero long term health risks. Only time Psilocybin Mushrooms will ever harm you is when they're not Psilocybin Mushrooms

4 Amphetamine

It made me feel happy, excited, wakeful, sharp, alert and lasted for about 4 hours And started about 4 min after I snorted a fatass line...I was using it daily for 2 months And then I stopped..I was a bit dizzy And more hungry (which was a pro) And maybe a bit tired And moody...but after a week id say that dopamine and norepinephrine levels went to normal naturally And that was it...And o expirience with a lot of narcotics and drugs and speed (amphetamine sulphate) almost had no bad effects.

Using in excess can cause heart problems, but overall, it's one of the very few drugs that doesn't impair mental abilities (and in fact strengthens them). It's the only drug on this list you can drive on.


Honestly, it doesn't harm you physically. But if it goes wrong, it could change your life and ruin you mentally. When you get that much of a kick and you get off it, it really hits you and in some cases it can cause depression

This popular club stimulant is actually safe, though can be unsafe if you don't bring anything into the club to cool you down, as the drug increases your heart rate to potentially unsafe levels.

As long as you test it and make sure that it is 100% mdma or at least close to it, you should be fine if you take it in the right circumstances: small dosage, uncrowded/hot area and not to drown yourself in water. the buzz lasts for about 6 to 8 hours and leaves you feeling very euphoric. if taken in high doses you can begin to "gurn" which can result in a sore jaw the next day as well as you looking like completely munted, as well as create anxiousness and increase in panic which can go wrong very fast. the only way u can die on this drug is if you take extremely high doses and or have other dangerous drugs combined within the drug. nowadyas the "half a pill" rule should be frequent across all users as you never know whats in these pills anymore and it can be hard to find a completely pure MDMA pill.

Once you test your pills and powder and do common doses, once every 3 months I don't see any problems. I've been doing it once every 2/3 months since I was 15 and I'm happy to say its matured me a lot, I don't know if it's me but I always feel much older and mature after a night out.

6 Mescaline

Mescaline, along with most psychs, is incredibly safe even with overdoses.

I think this should be first... Even less harmful than marihuana

By far this hallucinogen is very spiritual.

7 Ketamine

Ketamine is a hallucinogenic dissociative rave drug that needs to handled with care. While overdoses are statistically trace, Ketamine users are strongly cautioned to measure to how much they take. Long term use can lead to addiction and bladder problems.

I see ketamine as safer than alcohol in the societal sense because ketamine does not (a) result in a complete loss of self-control and inhibition, (b) does not provoke violent behavior across the country.

Ketamine is a hallucinogenic drug that is actually legal to use in therapeutic settings and can be helpful for many people seeking treatment.

K is insidiously addictive, but fairly easy to withdraw.

Just don't overdo It and watch out for bladder problems.

The ketamine at high dosages is used as an anesthetic. the ricreational dosages are very low

8 Khat

Khat is the keton-equivalent of methamphetamine ( the beta position on the amine chain has a oxigen atom with a double bond C=O. The beta position on the amine chain of methamphetamine has a hydrogen atom with a simple bond CH-H ). It can be prepared the synthetic route or it can be found in its natural state in the Khat-plants. It's less powerful than methamphetamine but has the same effects. It also have all the adverse effects of methamphetamine. Not one of the least harmfull illegal drugs at all because its as harmful as methamphetamine. It is a stimulant of the Phenylethylamine category, so you can't compare the effects of Khat with caffeine or cocaïne ( like one of the comments say ) which are totally different molecules.

Most people don't know about this drug due to the fact that it's only used in a few locations around the world such as East Africa and the Southern Arabian Peninsula. It's basically their version of Nicotine.

It's a stimulant that's stronger than caffeine, but not exactly cocaine.

It's relatively safe

9 Cocaine
10 Heroin

People seem to not understand that in addictive drugs like heroin, methamphetamine, cocaïne etc... there's also tolerance of the drug that plays a role. When you take small doses (not dangerous), it will stop to have the desired effect at a given moment because your body can tolerate the dose without any effects, so you have to take a higher dose to feel the desired effect that you once had with a smaller dose. This tolerance will increase more and more till you have to take dangerous amounts of the substance just to feel an effect of the drug. And when you come close to lethal doses, it's obvious that all those drugs aren't that harmful anymore.

Shoot up everyday for 3 years nothing happened yet besides happiness.

I might have lost my job and murdered my family but I'm happy right? *Cries*

Nothing like some after work heroin to stop the shaking

The Contenders
11 Magic Mushroom

Mario is a drug addict then.

This is not that bad

12 PCP

PCP can be used date-rape, causes poor judgment, impairs coordination, can be overdosed when binged on, kills brain cells, causes possible organ damage with long term use and a small portion of it's users become violent.

Actually, I described alcohol too.

13 Fentanyl
14 Methamphetamine

Methamphetamine (sold on the street) is the world's deadliest drug next to heroin due to it's very high addictiveness, neurotoxicity at high doses and a long depression-filled withdrawal.

It is, however, a prescription under the name of Desoxyn. It's rarely prescribed. 99.9% of people should not take this prescription, but it is used as ADHD medication for people who have tried everything and failed. The reviews on it from patients are surprisingly positive. Horror stories are minimal, and less than that of many other prescriptions on the market.

If you're taking Desoxyn at low doses and have a legitimate prescription for it, you are responsible, and you follow the laws regulating this drug, it's not going to be anywhere close as street meth.

15 Steroids

If you don't overdo it its actually safe

Give you muscles but make your pp small so no because I wanna keep my 12 inch pp

16 Flakka

I've been on this drug for 5 years now, lost a few limbs, but I mean, who really cares?

17 DMT

Most people don't know this, but DMT is safer to use than either LSD or Cannabis.

Never tried myself but I know for a fact it is much safer than fentanyl

Safest drug you can use.

Trip out kids

18 Nitrous Oxide

NOS is very safe as long as you break to breathe oxygen

No negative side effects just breathe oxygen too

Nitrogen oxide has oxygen therefore is safe

19 Desomorphine

Cheap and safe and you get a cool zombie look which is really cool.

Most dangerous drug ever 15times stronger than heroin

20 Jenkum

Just don't mix it with other substances and enjoy your jenk, you'll have a wonderful and insightful experience.

It can't really hurt you... I mean... its coming from YOUR body...

21 Scopolamine

It's a date-rape drug. The story on this drug is that all someone needs to do is blow it in your face and you instantly submit into all of their demands. It does sound a bit far fetched, but me personally, I'm staying away from this one in any event.

22 Codeine/Promethazine Syrup
23 Jenkem
24 Salvia

3 minutes of trippy weed

25 Captagon
