Why does science not give people a cure for cancer?Is marijuana/cannabis a cure for cancer?If cannabis can cure cancer then why did Bob Marley die of this disease?

Most people believe that cancer is like a flu; a cold, something we can shake off. But it is not.

I’m a computer scientist in a genetics world, and I came to realize that “cancer” is a normal process of life.

All throughout history, humanity has been seeking eternal life and longevity. It’s not a new quest. Nearly everyone in the medical field is working to prolong life and allow us all to be closer and available for our loved ones.

Cancer, to put it plainly, is a label for “failure to keep consistent DNA”.

Our DNA and protein structures replicate at an alarming rate. Faster than most of us would imagine. It’s mentioned that some parts of the human body replace themselves every few years. New skin cells, new hairs, muscles, and livers healing from alcohol. Billions of cells are replicated to heal damaged tissue. Billions of cells replicate to grow us into adulthood and beyond.

When replication occurs, there is a very-very-very small chance that the replication will have an error.


In most cases, this is fine. A skin cell with an error in it will be created, it will live, it will duplicate, and then the skin cell will die. A human cell has 3.4 billion nucleotides, where only 2% are critical for protein expression. This allows small benign errors to not have an impact.

However, some specific genes in that 2% are critical for cell growth and cell death. When the instructions for “grow every 5 days; die after 5 days” becomes “grow every 5 days; die every 15 days”, we call that “cancer”. Likewise it can also end up as “grow every 2 days; die every 5 days”, thus the equation for replication becomes unbalanced.

With more cells growing than they are dying, there is a greater and greater need for resources; cancer ends up stealing vital nutrients from other critical organs.


It is not that science is holding back, but moreover science is still trying to understand it. It’s important to know how it works, how to control it, and how to make sure we don’t cause additional imbalance.

When technology is created without rigorous testing, it’s working on assumptions. And assumptions can possibly hurt a loved one rather than help them. Worse, it may actually kill them.

Today, at the cutting edge of cancer research, research is dealing with the billions of permutations that might occur. Some cancers are “grow every 2 seconds; die never”. Some are “grow every 5 days; die never”. Some are “grow 16 times every 1 second; die every 5 days”. Each one requires a different approach, therapy, or method of management.

Today, science has already given us a few methods:

  • Cut it out
  • Burn it with radiation
  • Freeze it to death
  • Target it with chemicals
  • Ask the immune system to help
  • Replace it with someone else’s

Science is working on more methods:

  • Identify it earlier
  • Cut it out more safely
  • Burn only it with radiation
  • Better targeted chemicals
  • Hack and hijack the immune system to do our bidding
  • Grow replacements on a mouse!

This poor mouse is helping humanity! Cow cartilage cells were implanted into the mouse and grown so we can better understand how we might grow and regenerate organs for humans. (Vacanti mouse – Wikipedia)

It looks sad, but science is not blind. There are monuments that pay homage to these heroes. Like this one: (Monument to the laboratory mouse – Wikipedia)

Altering the “force of nature” is what scientists all around the world are working to control. Unfortunately, Mother Nature is very mean when we don’t play by her rules. This is a great meme that’s been floating around:

“Nature wants 5 of your 7 children dead. It wants you dead by 50. Everything better than that is brought to you by science and technology”.

At my lab, we are developing greater detection tools to identify mutations that cause cancer. We’re working on new methods to detect cancer in tissue, in blood, in <name your favorite body part here>.

Fulgent Genetics – Leader in Next Generation Sequencing

It’s a massive undertaking to combat the forces of nature. It takes time. It takes sacrifice. It takes generations of scientists to take the universe we are given and push it to allow just a few more years with our loved ones.

I understand the anger, the worry, the wish to point fingers at science, at companies, at faceless entities for not preventing our losses.

In June 2018 cancer has taken yet another one of my friends. Kind hearted. Friendly. Always willing to help. He went out of his way to get to know you, to understand your needs, to be impactful with the people he knew.

I wish science already had the answers. That technology already existed. That nature wouldn’t take wonderful people away. This is my friend Hao Hoang’s family spreading his ashes over Malibu. They found Lung Cancer in November 2017. They tried therapies in early 2018. Science couldn’t keep him. Nature took him in June. RIP.

It’s moments like these that reinforce why I love science. Why I make technology. How we can all play our role innovating ways to keep our loved ones longer. Build things to make this life better. Solve problems to reduce suffering in the world.

Can cannabis cure cancer?

The overuse and misuse of opiates is out of control in this country. Legalization of cannabis is the answer. I doubt the Pharmaceutical monopolies will agree with this!!

There is NO definitive answer. Existing evidence suggests that it can harm, as well as help. And the effects have only been studied in labs, not clinically cleared. In some cases, it might help – for example with mitigating pain, or combating the loss of appetite and wasting away which patients often face during cancer treatment. But an actual effect on cancer cells, as such, is NOT well-established.

Point to be noted : There is also evidence suggesting that it could have negative effects which may enable the cancer to become more resistant and progress over time. Additionally, certain side-effects it can cause in the long run can add-on to the misery of the cancer itself. Plus, you have plenty of hoaxes and frauds being run in this name. So well, it’s basically your call. The evidence is on the table.

I’ll advise you to take 5 mins and read on though.

THE Answer:

The basic concept of quoting marijuana as a medicinal product is originating from the activity of the cannabinoid chemicals. Cannabinoid receptors are protein molecules present on cell surfaces. When you ingest substances containing cannabinoids, its picked up by these receptors (as the name obviously suggests). Note though, “cannabinoid” is the name of a large family of chemicals – both synthetic and natural.

These receptors are present mostly on the brain and neural networks and govern a variety of functions ranging from pain, energy metabolism, immunity, memory etc. (explains why you get a high from it …. it just activates certain neural networks). It’s these properties that make it interesting for therapeutic purposes – notably, as has often been claimed, for cancer as well.

Lab experiments over the years have presented varying results.

Some indicate that cannabinoids help interfere in 4 crucial processes of cancer cells –

  1. The enhance cell death (apoptosis) rates
  2. They interfere with growth signals of cancer cells
  3. They curtail angiogenesis (blood vessel growth)

However, the flip side is that discouraging observations like the following exists as well :

  1. They interfere with the immune system’s ability to recognize and act against cancer cells
  2. Certain cancer cells develop resistance to it over time and grow/spread more aggressively – pretty bad news
  3. Most of the positive results above were achieved only by using highly purified compounds in lab, sometimes in association with other drugs. NOT as marijuana per se.

Another significant let-down is that a huge proportion of these studies are very unprofessionally conducted and hence have low credibility – which makes accepting these comforting sounding results dangerous to accept blindly.

So what about the other effects of marijuana ? The famed “pain-reliving” effect?

Let’s look at a very similar compound : cannabis oil.

Well, here’s the bright news. It is generally considered acceptable to use cannabis for palliative care i.e. not exactly as therapeutics, but for pain-relief etc. However, the issue with orally ingesting it as cannabis oil / smoking marijuana is that the dosage cannot be monitored – and hence the negative effects can start to kick in pretty soon. Not to mention the potential for abusing it for recreational purposes also arises.

Consider going in for the mouth sprays type cannabinoids. Dosages are usually well-calibrated and safe. However, it is usually advised to go for far more effective, and much safer alternative drugs ( anti-nausea, anti-sickness etc.) that have been developed over the years. These are actually pretty much available, and are any day a better option. At least you don’t have a big risk component attached.

Personally speaking, I believe the entire scenario of marijuana’s benefits is highly over-hyped. You have far better alternatives available. Medically approved, safe drugs. It’s just that “marijuana” sounds better to the public ear. The added attraction of something primarily viewed as a source of addiction and fun being potentially beneficial is what endears it so much to people. I would strongly advocate against you, or anyone else resorting to this as long as options are available. Which is most of the time.

If cannabis can cure cancer then why did Bob Marley die of this disease?

Because in serious scientific studies, cannabis has not been found to cure cancer. It has been shown that cannabis slows metastization, and this means amazing things for some types of cancer, prostate, breast, to name a couple. I am 100% pro-legalization but always question anything that says “Cure” in my opinion. I’ve witnessed Cannabis activists tell people dying of cancer that they just need to try cannabis! That’s incredibly rude not to mention, scientifically impossible and kind of horrible to yell at someone with cancer.
Question everything! Here’s a great site that doesn’t do one sided reporting on the subject of Cannabis. I do like Hightimes and other sites, but they are notoriously biased when it comes to promoting cannabis and aren’t always objective in their reporting.
Bob Marley died in 1981, officially due to malignant melanoma, a dangerous type of cancer that was found on his toe. It’s not quite as simple as it sounds, though.
Bob Marley’s medical records were never made public, but according to most accounts, he did eventually allow for a skin graft in place of a full amputation. It seems that if this procedure did take place, it was either ineffective or simply too late. By the late summer of 1980, the cancer had metastasized throughout his body. While he was in New York City performing, Marley collapsed during a jog through Central Park. He performed for the last time in September of 1980 in Pittsburgh, a performance that was remastered and released in February of 2011 as Bob Marley and the Wailers Live Forever

What sources of yours can you give that even a little suggest that cannabis can “cure” cancer?
I’m sorry but there’s so many wrong factors in that question, I don’t feel I should answer appropriately…
EDIT: Okay after doing some 1 minute unnecessary research, here’s a good paragraph that I have found that summarises it beautifully (source is reliable):
But claims that this body of preclinical research is solid “proof” that cannabis or cannabinoids can cure cancer is highly misleading to patients and their families, and builds a false picture of the state of progress in this area. For example, we’ve taken a look at more than 30 scientific papers that are often claimed to “prove” that cannabis cures various types of cancer. [UPDATED KA 21/07/14]”Cannabis, cannabinoids and cancer – the evidence so far 

I’m afraid that you are (like the article suggests) one of the mislead recipients of unclear research.Cancer is an extremely complex biological flux of mutated cells and tissue, which spread with uncontrollable malignancy to other parts of the body through cellular division. The two main reasons we cannot “cure” this affect is because:

  1. It is within a natural system that is the human body, and therefore the body registers

    the process as biologically ‘un-foreign’, making it difficult to combat the process internally.

  2. It requires control and treatment of Individual cells relating back to the “singularity” that is the tumour, or origin of malignant growth.

New research has suggested that drugs such as ‘cannabinoids’ prevent the initialized growth of malignant cancer, which ultimately is derived from the same molecular compounds as ‘cannabis’ – the article explains it in more depth.

Thus far the research has proven non-operative. Now I’m a Theoretical Physicist, so I have no expertise in the field, but I can just about work out that smoking cannabis will not stop you from getting cancer by any means whatsoever…

…Call me crazy, but that’s just a little theory.

Bob Marley had melignant melanoma in his toe which he refused to amputate due to the fact that he was Rastafarian. Rastafarians hold Leviticus 21:5 very close to them which states that amputation is sinful. He was diagnosed with it in 1977 after receiving a foot injury playing soccer. Both a tumor nor Mariquana, had anything to do with his death. If anything being Rastafarian killed him.

Because cannabis can’t cure cancer. What marijuana can do, sometimes, is to relieve some of the side effects of treatment, like nausea and vomiting. There is a form of brain cancer for which marijuana oil seems to be very helpful. But marijuana doesn’t cure cancer. Some people who don’t care that they discourage people from getting treatments that might actually prolong their lives are making that claim. Don’t believe them. It can be a fatal mistake
