You answered your own question, you need to do some research!
All the misinformation out there that says butane is poisonous are from uneducated sources.
No shit. That's why I created this thread.
If you read the stuff you linked, they're saying to make it outside because confined spaces + butane + spark = explosions.
"Here is Vector Butane's MSDS, the butane product most BHO is made with. It's not toxic, but is extremely flammable."
I find it hard to trust Matt Rize since he has his whole "my ice wax rocks hash oil is bad but look at my $100 shatterbros grams" agenda.
"Further, if homemade hash oil isn't properly "washed," solvents and other chemicals might be left behind — including pesticides, if the marijuana used to make the hash oil was treated with them."
Again, like I keep mentioning, purge properly and use good starting material and you're going to be okay.
The High Times article that you linked at the end is the exact same article that has the "hydrocarbons aren't dangerous in small amounts" bit I quoted some posts up.
".000,000, 055 X .000, 0035 = .000,000,000,000,192 or 200 parts per quadrillion in the butane used for extraction.
Assuming a 40 gram trim extraction, using 300 ml of butane, and yielding only 10%, 300 ml butane would deposit .000,000,000,058 ml of 1,4 Dichlorbenzene in 4 grams of concentrate.
.000, 000, 000, 058 ml X 1.2475 gms per ml = .000,000,000,072 grams of 1,4 Dichlorobenzene in 4 grams of concentrate.
.000,000.000,072 grams divided by 4 grams =.000,000,000,018 or 18 parts per trillion.
110 ppm TWA Ceiling (.000, 110) divided by residual 1,4 Dichlorobenzene level of 18 parts per trillion (.000,000,000,018) = 6,111,111 or about one six millionth (1/6,000,000th) of maximum allowable exposure level.
4 grams of oil will produce about 20 200 mg hits, so each hit would be about 1/20th of 1/6,000, 000, so exposure per hit would be about 1/1,200,000,000 of the 110 ppm maximum."
Emphasis mine, just to point out what kind of ballparks we're talking about.
Thanks for that break down of the ballparks. It seems pretty minute to worry about...
I understand many of the links don't say "BHO isn't safe". In fact many of them simply leave the question unanswered and provide more reasons why they are safe. The point of this thread is that the augment exists. Somewhere in every link I provided the argument can be made that BHO is both safe and not safe to CONSUME (I know a lot of the articles mention the hazards of making BHO, obviously it's dangerous I'm not arguing that. This thread is solely about health concerns from using BHO) A lot of the links I provided have a stream of conversation where you can see the argument unfold. Certainly there is more information pointing that BHO is safe. However we would be stupid to not look at the other side and find out if it is as safe as we think.
I appreciate you breaking down those numbers, that helps me understand better. Still, I'm hoping to hear both sides of the argument. There is a lot more to learn...
