I'm surprised you like the temp of 383. I find anything over 375 gives a burnt tasting vaping experience after the first balloon. Research by the NORML California division said the following:The vaporizers I use are at Barney's coffeeshop and are set at 383. Of course health is important, but that's supposedly around the optimal setting to vape THC. The balloon is to cool it off so...
And thanks for the concern. It's not something I just picked up though. I've been tested a few times by lung specialists and despite having smoked for over 2 decades my lungs seem healthy. I frankly don't know exactly what allergy it is, a common pollen allergy. Plus I smoke too much (which is where the vape comes in too, please don't make me point out we Dutch pollute our joints with tobacco... there you go...). Comes and goes and doesn't seem to be seasonal. I've barely needed my inhaler since I picked up home growing again, I don't need it days after I vaped, I highly suspect I won't need it at all if I'd only vape (which will never happen).
Does your doctor have any source that confirms the bold part, seems he's talking out of his ass like most doctors do when it comes to mj. Thanks for the info nevertheless, something to look into for sure.
"The vaporizer produced THC at a temperature of 185° C. (365° F.) while completely eliminating three measured toxins - benzene, a known carcinogen, plus toluene and naphthalene. Carbon monoxide and smoke tars were both qualitatively reduced by the vaporizer, but additional testing is needed to quantify the extent of the decrease."
and
"Significant amounts of benzene began to appear at temperatures of 200° C. (392° F), while combustion occurred around 230° (446°F) or above. Traces of THC were in evidence as low as 140° C. (284° F)."
That being said, at the coffee shop you're vaping pretty close to the temp where "bad things" start to happen.
Personally I've found 369 to be the best temp for flavor and the control of harshness.
About the doctor, I'm not sure where he gets his info. He's an old Indian guy though and they use a lot of cannabis in India so I feel he probably knows what he's talking about.
