IMO parents of young children have no business doing street drugs, period. Fentanyl will kill you, and is increasingly mixed into all street drugs. However innocent you might think an occasional roll on MDMA with your wife after bedtime might be, you are taking your life into your hands in unnecessary risk, rolling the dice on orphaning your children for a night of (illegal) "fun". Why would you risk it? When you could die, get arrested and publicly humiliated, have your children taken from you, or be incapacitated in an emergency?
All this pilpul around how it would be totally fine if the laundry was kept up with is a crock. If you're a parent, you don't have the right to take unnecessary risk with illegal behavior, because eventually, something bad will happen and you have necessarily placed a drug above your kids.
