on average, i'll get about 2-3 g's of quality oil off 14 g's of bud in the o'kief tube.
Yumm-o
Below you will find a lil info on a substance that can NOT be Purged ...even under High vac.
Or by "Triple filtering"
Mercap...is the LAST thing added to the Butane after the "Filtering"
All the "Oil Heads" out there ever wonder why you can't buy "Oil" @ a Coffee Shop?
That would be because its Toxic
and with an LD-50 of only 675ppm thats some toxic shit

3. Hazards Identification
EMERGENCY OVERVIEW
Irritating to the eyes, mucous membranes and respiratory system. Inhalation may result in
pulmonary paralysis, sudden collapse and death. Exposure to high concentrations may result in
acute hemolytic anemia. Extremely flammable. Poison gas.
EYE EFFECTS:
Low concentrations will generally cause irritation to the conjunctiva. Repeated exposure to low concentrations
is reported to cause conjunctivitis, photophobia, corneal bullac, tearing, pain and blurred vision.
SKIN EFFECTS:
May irritate the skin upon contact.
INGESTION EFFECTS:
Ingestion is unlikely. Methyl mercaptan will irritate the mucous membranes causing a burning feeling with
excess salivation likely. Irritation of the gastrointestinal tract may also occur.
INHALATION EFFECTS:
Exposure may cause fever, cough, shortness of breath, a feeling of tightness and burning in the chest,
pulmonary edema, respiratory failure and collapse. Headache, loss of smell, dizziness, staggering gait and
heightened emotions may occur. Memory loss, damage to the central and peripheral nervous system, tremor,
convulsions and coma may result. Individuals exposed to high concentrations may develop acute hemolytic
anemia and methemoglobinemia.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Individuals with pre-existing conditions of the heart, lungs, blood and nervous system may have increased
susceptibility to the toxic effects of methyl mercaptan.
i would say the range of weed most found, is between 10-25. so 17.5 is the average around here. less than 15 is meagre, more than 20 is great. between 15 and 20 is typical.
we all known that Vector, King, colibri, etc do not contain mercaptans for a few obvious reasons
1) we cant smell them (which is the entire purpose for their addition to hydrocarbon fuels in the first place, and our noses have a ridiculously high sensitivity for mercaptans, smelling them at PPB concentrations in the air)
