Sobriety is a wonderful thing but if people who have those issues let down their guard for more than a bit, no matter how much time can relapse.
I think this is what probably happened, and at age 61 considring what she put her body through all her life substance wise it probably was the last straw.
Wouldn't be surprised if all she did was one or two things like coke and other shit was mixed in the blow, that has been known to happen alot lately, last weekend seven overdoses outside of toronto because the blow they were taking had fentanyl mixed in.
years ago you had drug dealers having to mix 10 parts this to 1 part that, now its 10 parts this to 1/100 of this fentanyl shit, and lets be frank, most dealers probably failed both math and chemistry in school and were not experts at chemistry like the whole walter white breaking bad nonsense fantasy.
I hope that the people making fun of her, being smug girls and calling her "weak" never get into an accident or something and get hooked on pain meds after. That is a typical spiral for those who "never in their life did drugs before" these days (oh brother

)
I have seen too many people who never would touch anything in their lives end up addicted to shit because of medical circumstances that happened which were out of their control, and the doctors, pharm companies and government play the pretent faux sympathy card but are full of shit and part of the problem in the end
