carcinogens

I mean, it stands to reason that combustion produces carcinogens, but cannabis is not tobacco.

This means that cannabis smoke has the same carcinogens (substances that cause cancer) as tobacco smoke, although concentrations of these may be up to 50% higher.

If that's the case, it's not really a general rule that small exposures to carcinogens prevent cancer.

And of course paying $0 and not being bombarded with carcinogens is a big bonus.

Preliminary findings suggest that marijuana smoke activates cytochrome P4501A1, the enzyme that converts polycyclic hydrocarbons, such as benz[a]pyrene, into active carcinogens.

We know that cannabis smoke contains a bunch of the same carcinogens as tobacco smoke.

And yes, human-being can make the difference whether they have those unnatural carcinogens or not.

Meanwhile, sunlight and estrogen are known carcinogens, but we don't hide in dark caves and cut out ovaries.

There are a lot of 2A carcinogens that you're exposed to far more routinely.

Cancer is a real physical process, triggered by real physical causes (carcinogens, genetics, etc.)...

The theory being that higher chance of mutations with sperm as you get older (and as you have been introduced to more radiation, carcinogens, etc).

I use it to encompass thousands of different chemicals like free radicals, known carcinogens, etc.

Avoiding carcinogens may reduce your cancer risk, restricting yourself to things that are "natural" won't.

It's not about "tolerance", it's about not forcing others to inhale the same carcinogens as you because they do not want to get lung cancer.

There are plenty of "natural" carcinogens too.

At the very least, once the carcinogens have done their job and induced a cancer washing them out would be a bit of "shutting the barn door after the cows have run away".
