It's not accurate to say any amount of alcohol increases your risk of cancer. There is clearly a threshold amount and one droplet of red wine in a glass of water one time in your life is not going to increase cancer risk in any measurable way. The threshold amount does matter if people want to make the smartest choices and still enjoy life.
The same can already be said of cannabis.
"People who use marijuana have an increased risk of heart disease and heart attack, according to a large study led by researchers at Stanford Medicine.
The study also showed that the psychoactive component of the drug, known as THC, causes inflammation in endothelial cells that line the interior of blood vessels, as well as atherosclerosis in laboratory mice." [1]
Other studies have shown the risk of heart attack goes up in the first hour after smoking cannabis.
Prohibition doesn't work. And we need loads of more studies like this so folks can be well informed in their choices.
However regulations and taxes do work. Smoking cigarettes continues to become less and less popular thanks to information, higher taxes, and other regulations.
Considering how popular cannabis is, we should be funding more research so we can make informed choices, and at tax it at a level that recovers the actual cost to society.
