Cannabis Use Linked to Epigenetic Changes, Cancer Risk

Used cannabis for 55 years. Switched to temperature controlled vaping for 10 years to avoid inhaling benzene and other toxic vapors from the combustion of plant material.

Now using only edible forms of cannabis to totally avoid inhalation of toxic vapors.

Wondering if any studies exist relevant to consuming edible THC and CBD?

So unrelated study and some old studies were mashed together to draw a conclusion and published by "unbiased" source. Another fine study by a prison colony.
