Can i ask where you got those figures from?Yeah I fucked combustion completely around 2 years ago. I have been vaping for 4 years or so but only switched to full time vaping 2 yrs ago. It was so worth it, my lungs are so much healthier from switching to vaping only.
I'm planning on never smoking again.
The reason i ask is that i have a few studies here that contradict this and state that combustion actually can deliver up to 80% while destroying the remaining 20%. Whereas vaporization (in this case the Volcano with controlled variables) resulted in a 60% delivery with the remainder of actives still in the sample and a much smaller part of that re-condensed on the surrounding surfaces (tested with ethanol bath).
(also, to clarify the studies compared joints to pipe/bongs and used a bong to represent combustion - it was found up to 60% of THC can be lost in a joint though side-smoke)
Thus the study posited vaporization to be in fact more efficient, though in some cases less effective in terms of rate of delivery. Even though in this study the vaporizer delivered only 60% compared to 80% with combustion, no actives were destroyed and could still be collected for use.
Also, this was with all sparkling clean equipment - i imagine if your pipe gets dirty then the 80% max delivery will drop off a significant portion.

) in well over 20 years! I was smoking 15 cigarettes a day by age 12 & at least 30 a day from age 15-36. I also started smoking cannabis at 12 & was smoking at least 10g a week from age 15-28 & then weekend smoking 2g from 28-33. From 33-36 I was combusting at least 14g a week. Not ridiculously huge amounts but very consistent habitual use over the years.
. I will add that was through separate watertools.
. I have not smoked cannabis since then & have rejected offers of smoking multiple times when out & about. I was still smoking cigarettes like a chimney though & quitting them was the reason I started vaping in the first place! One day I decided enough was enough & purchased nicotine replacement therapy to use.

I just couldn't! My buddy who smoked invited me over to his house to spend the night. 
are just a few good examples of how the two of us felt. He packed a big bowl in his bong and handed it to me with a lighter. 
I cough hard! For a solid 10 minutes. And this was maybe 1/3rd if even the size. My throat was not happy! Heh. I slept on his floor, so comfortable. 
at 15. Later, the 3 of us found out we all played instruments and became a band of stoners. Music, smoke, music. Weekly-ish.
) for cardio. But, even then I'm coughing up some black stuff now and then, and generally feel shorter of breathe. The way I smoked, I power hit bongs. So almost always upwards of 30 second hits. I'd maybe only take 1-3 bowls a day though, so I wasn't overdoing it too much. I started using hemp wick, and saw the Grasshopper vaporizer on Indiegogo. It looked amazing and perfect. It was going to be my first vaporizer, I just knew.
No, I'm whacking my face on the floor.
Over the final term, I took mushrooms and LSD (separately).
I went to my buddies house, and he wasn't too sure about it. We knew that we should be vaping, as getting our cards renewed the doctor suggested that we really should. I told him I had one on the way (well I did haha). Few weeks later, I get that surprise gift.
I eventually said screw 'em, and would say no I'm not going to smoke, I've stopped. Many of my friends respected my choice, and would vape with me instead of smoke.
It was about damn time I manned up.
