Is a vaporizer really much healthier way to smoke medical marijuana? Or it's more of an a kind of market trick? I'd like to know how it works in scientific words. All I googled was somehow related to the market.

Its healthier in the sense that your not inhaling burning leaves and stems its cleaner going into your lungs but I'm no scientists... but the vapo basically bakes it instead of lighting it on fire... bho is also cleaner

It is believed to have a better absorb rate into the body

Kind of like a bong.

No its nothing even close to a bong

More like an inhaler used to ingest medicine into the lungs when treating COPD. Which doesn't make sense for marijuana because what form would it take and are they able to change its form as I know it, which is leaves?

I am dubious about it not burning, because I have tried one and it was filled with smoke. Wikipedia says it's actually vapor, and 'little to no smoke is produced.' I had a coughing fit from one puff. Years ago I smoked from a bong and it seemed easier on my lungs. The vaporizer does trap all the vapor/smoke and keep it inside a one-way valve until you inhale.
