Thank you to the people who actually answered my question. The rest that are only interested in making the point that no way pg/vg can cause any problems can read the msds sheet. I copied some below. notice it says DO NOT BREATH . I have coughed up pinkish phlem for a long time and have seen many doctors. It is usually from sinus drainage, but can also happen from coughing violently. Yes it can also mean something bad. I was asking about the vaping because both times it has happened recently was after vaping liquid bought for refilling. It had not happened since last winter, and there was 4 days between the 2 days it happened recently, i did not vape for the 4 days it did not happen. i then vaped and it happened the next morning. So it was not like your anus . maybe if you were not such a .... to people trying to get help with this your .... would not have fallen out.
Material Safety Data Sheet
Propylene glycol MSDS
Potential Acute Health Effects:
Hazardous in case of ingestion. Slightly hazardous in case of skin contact (irritant, permeator), of eye contact
(irritant), of inhalation.
Precautions:
Keep away from heat. Keep away from sources of ignition. Empty containers pose a fire risk, evaporate the
residue under a fume hood. Ground all equipment containing material. Do not ingest. Do not breathe gas/fumes/
vapor/spray. Wear suitable protective clothing. In case of insufficient ventilation, wear suitable respiratory
equipment. If ingested, seek medical advice immediately and show the container or the label. Avoid contact with
skin and eyes. Keep away from incompatibles such as oxidizing agents, reducing agents, acids, alkalis, moisture.
Chronic Effects on Humans: May cause damage to the following organs: central nervous system (CNS).
May affect genetic material (mutagenic).
May cause adverse reproductive effects and birth defects (teratogenic) based on animal test data.
Special Remarks on other Toxic Effects on Humans:
Acute Potential Health Effects:
Skin: May cause mild skin irritation. It may be absorbed through the skin and cause systemic effects similar to
those of ingestion.
Eyes: May cause mild eye irritation with some immediate, transitory stinging, lacrimation, blepharospasm, and
mild transient conjunctival hyperemia. There is no residual discomfort or injury once it is washed away.
Inhalation: May cause respiratory tract irritation.
Ingestion: It may cause gastrointestinal tract irritation. It may affect behavior/central nervous system(CNS
depression, general anesthetic, convulsions, seizures, somnolence, stupor, muscle contraction or spasticity,
coma), brain (changes in surface EEG), metabolism, blood (intravascular hemolysis, white blood cells - decreased
neutrophil function), respiration (respiratory stimulation, chronic pulmonary edema, cyanosis), cardiovascular
system(hypotension, bradycardia, arrhythmias, cardiac arrest), endocrine system (hypoglycemia), urinary system
(kidneys), and liver.
Chronic Potential Health Effects:
Skin: Prolonged or repeated skin contact may cause allergic contact dermatitis.
Ingestion: Prolonged or repeated ingestion may cause hyperglycemia and may affect behavior/CNS (symptoms
similar to that of acute ingestion).
Inhalation: Prolonged or repeated inhalation may affect behavior/CNS (with symptoms similar to ingestion), and
