I can help you understand how cannabis cures cancer, if you'd like to learn. :)

Cannabinoids (there are 100+ different ones in cannabis, like THC, CBD, etc) attack tumor cells in the body, a process called apoptosis. This causes the cancer cell to close up and die, and all its contents are absorbed back into the body (recycled). This is a safe and clean way to remove cancer. Radiation (the most common mainstream treatment) burns and kills ALL cells (including healthy cells), and leaves terrible scars and nerve damage.
This was discoverted in 1974 by US President Nixon, but he had the studies covered up and silenced. It was rediscovered in the 1990s by Spanish university researchers, and now the entire scientific world knows about it.
The only people who don't know about it are certain members of society who remain brainwashed by the propaganda they received from government for decades, saying that cannabis is dangerous and unhealthy. They even told us that cannabis CAUSED cancer... but that was a lie. It truly CURES cancer.
Thousands of university studies from all over the world have confirmed this fact, my friend. I don't mean to be rude when I tell you this information, or to make you feel foolish. Many people don't know this. But now you do, so please, don't spread the wrong information that cannabis doesn't cure cancer. You might tell somebody that lie, who has cancer, and stop them from saving their own life. That would be very sad.
Here's some more information about this topic: Cannabis CURES Cancer!

I have information about cannabis for hypertension too, if you're interested. My wife and I have both done 10 years of full-time research into this topic, because she has cancer and overcomes it with cannabis oil, so we have become experts on the topic. :)
