"But Rachel also has another hobby, one that makes her a bit different from the other moms in her Texas suburb—not that she talks about it with them. Once a month or so, after she and her husband put the kids to bed, Rachel texts her in-laws—who live just down the street—to make sure they’re home and available in the event of an emergency.
“And then, Rachel takes a generous dose of magic mushrooms, or sometimes MDMA, and—there’s really no other way to say this— spends the next several hours tripping balls.”
The article says nothing about her husband partaking, so presumably there’s another sober adult present and no risk.
It felt implied (why text the in-laws?) but maybe not?
There may be a medical emergency where the husband needs to take her and leave the kids alone.
