I live in California, where you can phone up a totally legal delivery service and have marijuana at your door within an hour, or go to a dispensary and choose your strain by smelling a bunch of them. Marijuana is legal and PLENTIFUL here.
My husband and I are both multiple-times-daily marijuana smokers. We use it to control anxiety issues and pain that would otherwise require opioid medications (my husband had an injury that resulted in 5 knee surgeries including getting cartilage from a corpse -- thanks to marijuana, he is able to walk without a cane most days).
We have air filters in the house to keep the smell mostly at bay. We also find that the legal marijuana strains marketed in California smell less bad than marijuana in places where it's illegal wherever it's illegal, it's stinkier and more acrid, I suspect because one of the biggest things they breed these new legal strains for is a gorgeous scent some smell like lemon, or grape, or herbaceous florals. Mm.
I work in a creative field and often do work while under the influence of marijuana. My husband loves it before doing housework (he is a SAHD and does most chores), lets it all go by in a lovely pleasant haze.
And now I tell you the thing that will really shock -- I have a nearly-two-year-old toddler and another baby on the way. I smoked all through my pregnancy with my 20-month-old DS. Everyone says he's the happiest child they've ever seen, he knows all his colors and shapes and can name every letter of the alphabet, has a vocabulary of nearly 1000 words, has memorized picture books intended for children more than twice his age. He has been sick just twice in his life, both times with a mild fever for less than 48 hours.
In the last 3 years, while being a multiple-times-daily smoker and while dealing with pregnancy and birth and all that, I've increased my salary from $35,000 a year to $95,000 a year and am now getting recruited for jobs paying $150,000-180,000, though I don't want to leave my current employer until I have this baby and my mat leave is done (it's hard to get mat leave in the US, and I want to stick where I've got it "good" with 8 paid weeks, no joke, that's "good" here).
In places where marijuana is legal and easily obtained, people are much more relaxed about it and it's not generally considered to be scandalous to be around children with it. God knows it was far, far more harmful for kids to be exposed to cigarette smoke and cigarettes left around constantly -- tobacco is highly toxic if swallowed, while marijuana buds are not psychoactive until they are heated to a nice toasty brown, so if a child or pet ingested them, it would be a waste of perfectly good marijuana but would not have any effects on them except perhaps a very herby bowel movement.
For me, having my anxiety relieved is so great, it's enabled me to move up the career ladder and have babies. I have a lovely bond with my son and hope to have a similar one with DS2 due in March. Plus ... it's WAY more interesting to play toddler games when you're stoned. This is just god's honest truth. We've gotten (mildly) frustrated with DS less than half a dozen times in his entire life, and never get bored of playing pat-a-cake for the millionth time. He giggles, we giggle.
ALL THIS HAVING BEEN SAID: If your husband checks out on responsibilities while he's using, then that's no good! If you can't handle your stuff, then you shouldn't be using at a time when you have family and housework duties. I am probably one of the most pro-marijuana posters here, and even I think that it sounds like he's using this as an excuse.
