I agree with you AKJ, but you know that.
I just wanted to pop on here and say that I hate how society views people who use pot. How they inflict shame and guilt on those who already carry around too much of that.
Yes, it is not healthy for your lungs, but quality of life, in my opinion, should always be held above quantity of life. And I strongly despise that attitude of some who just feel it is okay for people/doctors would not only dismiss pain and suffering but also deny access to other pain medications just so long as it is not them who suffer.
Marijuana is unlike any other drug available to those suffering. So yes I too feel it belongs alongside all other mediations for pain and distress. And much like cigarettes, alcohol, cigars, chewing tobacco, and Rx medications (which all have some nasty side effects if we view them from the same lens), I strongly believe that as long as it is used responsibly and respectfully (as both it and cigarette smoke would severely hurt my excessively delicate lungs), then where is the harm just as long as the contents are regulated to be safe, except in the pockets of big pharmaceutical companies.
So I support you and others on here in whatever you choose is right for you, and wish that it was an option for me, even if not used. However, I applaud your efforts since you will be spending much time around your granddaughter. I relate my own 4 days of intoxication at the ripe old age of 3 months due to exposure to fumes during a brewery tour with bio family to that of any baby's exposure to secondhand smoke, legal or illegal.
I hope you can do it without experiencing too much additional physical pain, mental distress/depression, or ugly nightmares.
Best wishes to all who are struggling in one way or another in this regard,
Alex
