This was a stupid loss really... I worked in a major health care center and would socialize with nurses and nutritionists or even administrators but rarely doctors these women really did develop God complexes that would effect more than just their professional lives. They could basically do whatever they wanted - they save lives so nothing else matters.
Most non pharmaceutical street drugs are cut - lidocaine was popular for cocaine as it still numbed the nasal passages enough that powered sugar and lidocaine were often mixed and sold by wealthy kids I knew at the beach - they used to laugh about selling a small zip lock bag full for $4K... Did I say these were guys from wealthy families who went to the best schools... coke has always been used to get tang to bang in the middle and upper classes. Claims made to me were it had a numbing and prolonging effect for both men and women with out the whiskey dick syndrome in men.
Recent reports from the Sinaloa Cartel are that they pay columbians and bolivians about $12.5K USD a kilo and sell it for $25K in the USA - they grow their own opium poppies and it costs them approx $1,500 per kilo to produce and they sell it for $50K per kilo in the USA - the dirt bags who then sell to the street and or party crowd step on coke so much with lidocaine and even clear soluble dietary fiber that they have been adding a fentanyl booster - this is where the crazy shit begins because fentanyl is used by veterinarians to anesthetize large animals for surgical procedures...
https://en.wikipedia.org/wiki/Fentanyl
Fentanyl is approximately 80 to 100 times more potent than morphine and roughly 40 to 50 times more potent than pharmaceutical grade (100% pure) heroin
Drugs dealers being the amoral morons and mother killers they are mix or cut fentanyl in with both street cut heroin and street cut cocaine to make it seem real or better grade than it really is.... so considering who ever did the cutting was also likely high - without a spectrometer analysis users never really know the real potency or compounding of what they are putting in their bodies... Why heroin overdoses are rampant - hearts and breathing just stop - as are many coke overdoses as well.
That said there is a flip side to this story - she as an MD could have supplied the party drugs herself - the level of extreme addiction among health care pros is legendary due to their direct access to pharmaceutical grade opiods and cocaine (From injectable Morphine vials to bubble packs of Oxycontin or Oxycodone to Cocaine for nasal procedures - many performed by dermatologists) nurses especially can easily administer an aspirin instead of an oxy and pocket the oxy pill... Nursing homes are notorious for this as each oxy pill sells readily for $100 on the street...
During one of the severe recessions - after 9-11 I got a job delivering morphine kits and pharms for a sleazy immigrant run wholesale pharmacy that employed recent immigrant pharm grads with questionable green card status as in none - delivered narcotics including oxy pills to nursing homes for their terminal cancer patients with NO background investigations - In nursing homes since it was disruptive listening to patients scream while they were dying in agony from various types of terminal diseases they keep these patients as medicated as possible without killing them. Pharmaceutical grade meds can be plotted for absorption and dissipation based upon the patients weight and circulatory stats. The fact is in most medical settings for terminal patients where they die of "natural causes" it is the pain narcotics that finish them off at the end.
This is why using any kind of street "party" drugs especially coke and heroin that is always cut is so deadly and why one of the major growth industries are upscale detox/rehab centers... And why so many companies have pre-employment drugs screening.
I go through every womans medicine cab and even purse early in any relationship to see exactly what meds she is on - birth control - great - but any evidence of "party" narcotics and I vanish like a ghost and only ever give them my Hushed burner app number until I know whether they can be trusted or at least are clean.
