i like many others smoke tobaco still, you get the throat hit,which vaping doesn't give you. but if you want healthy, eat it as was allready stated.
second is vaping, no throat hit, but you get high. way more healthy then smoking,
bt we wern't ment to live forever, back in the day, neandethal man used to smoke it i reckon, some herb got put on the fire by accident and smokeing came about.
we all have cannabis receptors n the brain, were ment to take it, but i woould choose eating for health and longgevity
