Self-improvers, has marijuana helped or hindered you when it comes to your self improvement journey?

I want to know your opinions and whether or not it has helped you or harmed you or was completely neutral.

I know if you go off of research that marijuna makes the brain less neuroplastic and that lessen neuroplasticity makes it harder to form new habits and I guess as an extension of that concept break old habits, but I also know that there more than just research papers when it comes to self-improvement. I know it can ease the mind if you have one that runs 24/7 at high speed and gives you a treat that isn't that bad for your health if you vape and run the vapor thru a water piece.
