I and almost every pot smoker I know uses and have used tobacco with cannabis for decades, and it's not been good for our lungs. Here in the north of England we inhale and hold it in for as long as possible, nearly 40 years ago I started with Red Seal and BnH and now my lungs are damaged. I'm not complaining, but I have to stop smoking. I have had a go and bought (me and a pal who has lung cancer) a few vaporisers, but frankly we found them to be rubbish. The Volcano was stupid expensive at £250, and we just don't get very high with it, it's a party piece, a novelty,I feel self conscious holding the massive bag. We also tried the Pax and the Pro Storm2, whilst these we felt are better than the Volcano, you need spare batteries to use them and you still don,t get very high. The Dynavap works much better for me, you can take it anywhere, it uses a tiny amount of weed, or concentrate, if you by the special coil.I use a single small flame torch and get 5 'hits' without scorching the bud, going low temp to high temp a little bit each time (right to left). You can even make BHO with the vaped bud.Anyway using the dynavap is very familiar ground for pot smokers, you get similar effects, although oddly for me the high has a pronounced 'spiritual' feel. You can use it with almost any heat source, clippers, candles, twigs from a camp fire ect. My pal doesn't use his dynavap as he can't hear the click, he's using BHO and a dab rig - and a blow torch! I haven't given up smoking yet, me and my partner are quitting together. Heavy pot heads from the North of England will struggle to find equivalent effects with vapes, the Dynavap is surely worth a try as it has definitely stronger effects.
