Weed is not going to ruin your life the same way like benzos and alcohol would. If you smoke everyday then you probably aren't very productive, but you are not actively ruining your life.
Weed is dangerous because of how safe it is. It makes you ok with being bored and not progressing/growing as a person. Alcohol addiction will straight up make you homeless.
Ive honestly stopped buying the different strains have different effects talk. No matter what I smoke I get stoned and lazy af. Not that that's bad, it's just what happens.
I've definitely noticed a slight difference but no strain is going to suddenly make you productive. Maybe you want to be productive but you feel tired and crappy because you're too sober, and getting a fix helps. Doesn't mean the weed is actually helping you it just means you're addicted
Good that you know your self in that case. Not all bodies react the same way. I know folks who can't get high from smoking but do from edibles, and vice versa.
