I Vaporize pretty much exclusively because of my athsma. I love joints, and bongs but If I smoke, my lungs get really fucked up and I can't breathe properly for the next day. At first I vaped only because I had to, but now after a years worth of vaporizer use, I have found that it is much more efficient, and I really enjoy it more than smoking now.
Bubblers are probably the best--I usually like sharing/passing around and bongs can just tear through your supply.
Not to mention Bongs can really rip which can get you too high(yes there is such a thing, esp with the recent heads quality) and really hurt your lungs after a milky hit.
Joints/ blunts are wasteful, though imo the best way to consume mids or really enjoy the flavor of some good heads. I use spliffs for convenience/economy/inconspicuous factor.
Bowls are best for outdoor consumption(i.e. camping, hiking, etc.)
vaporizers just suck imo. The 'green' doesn't usually have the THC but it pulls off all the flavinoids that make smoking weed weed normally enjoyable. That and it really kills all of the normal ritual fun.
Edit: Nothing really beats the economy/insta-high a parachute consistently delivers
Oops, didn't realise this was in existence when I created the new megathread. In any case, its redundant, so it's closed, new MEGA is here: [MEGA]Methods of Smoking
