From a friend, FYI: ^
Vaping concentrates and oils: A battery-operated heating device, often fountain pen shaped which blinks when ready to hit (hence their nickname: "blinkers" or "pens" or "the Penjamin" and contain replaceable cartridges (aka "carts"). They heat a liquid containing THC (and who knows what else....) into a vapour or an oil concentrate containing THC (and who knows what else...) Theoretically, this method is healthier than smoking weed but being legitimately suspect of the "and who knows what else", there have been issues with heavy metals, etc.
Vaping "flower"/herb/weed: Heating the "flower" to a temp that is below combustion and usually in a range of 199-210 celsius and normally with most flower vapes, maxing out at a temp of 221 celsius -- all of which is below turning the weed to ash. When a vaping session is complete, there is no ash of any kind in the bowl. The weed is intact and at most is toasted or roasted usually to a light or medium brown colour. People will usually save this vaped weed which is known as ABV (Already Been Vaped) and easily confused by people who prefer alcohol rather than weed because ABV to them means: Alcohol By Volume.
ABV weed could technically be smoked. Loaded in a bong, a pipe or rolled into a joint but it would be pretty harsh and not as potent. People usually make a tincture from it or cook with it, make gummies with it, etc.
Provided the weed is of good quality and free from pesticides, chemicals, metals, etc. then out of all the options above other than ingesting the weed.......vaping "flower" is the most healthy. Or perhaps more accurately, I'd say it's definitely more healthy that smoking it. That's what I do. I have both a battery-operated rechargeable vape for flower that's very precise and I have some manual vapes that have a removable metal cap that's calibrated to "click" when heated to the proper temp. I just got this kind recently and it's got disadvantages; namely, it's far too easy to overheat this unit and combust the weed which is not what I want to do.
One more advantage of vaping flower rather than smoking it? The exhalations are barely noticeable and do not linger at all. Whereas, you know pot smoke does linger and can be very strong.
