I'm a child of the 60's....pot was sold out of my yearbook office. However....I have never, ever tried it, in any form. My ex and my kids on the other hand, use it all the time. Before it was legalized in Mass, my dd had to take her habit out of the house!!! I can't abide the smell of pot, never could. She is an adult, now 42. She currently is living with us....and although pot is now legal, I've told her she has to switch to vaping due to the smell. More expensive, but her choice. My ds and dd and their dad all use pot to self medicate, say it's for anxiety. Fine. And she tells me she isn't addicted. But, I beg to differ. Maybe not physically but certainly emotionally!!! She feels she can't deal with life without it. She's addicted, emotionally.
I've had this discussion with others. I'm not at all sure there are going to be people that never used pot because it was illegal that are now going to go out and get high. Yes, people drive while it is in their system, and I'm hoping for a method to come along to detect the presence of pot when stopped for less than stellar driving. And I tend to agree about cellphones are more dangerous in cars than pot smokers.
Pot, like alcohol, needs to be kept out of the hands of the young. For me, this is the biggest issue, underage use. Young brains aren't ready to use any substance with good results!!!!
