Is Cannabis ever permissible?

I think i need to stop smoking so much weed now that i’m coming to Christ. I admittedly have been using it for a really long time now and it will be hard for me to let go of.

But i still have like this itching question where i can’t help but feel like it’s okay in some situations. I really don’t understand how Catholic enjoy alcohol and cigarettes when it’s much more damaging to your health.

in my own life i can see sometimes its being a bandaid solution to lifes problems, And i think thats sinful, right? Imagine smoking weed first thing after a hard day at work. But sometimes its a positive in my life aswell. I love smoking a little bit of weed before locking in to a long run, hike, or a day of skiing. It’s also been great way for me to connect with some close friends from time to time on special occasions. Like i think there’s a responsible way an adult can use cannabis. Is that so wrong? If i chose to smoke weed in a controlled environment, don’t drive under the influence, I don’t negate any of my responsibilities.

Like what’s the problem? Is this really a reason for me to go to hell? Do i need to go confess my sins and deny myself the eucharist, just cus i had small puff of weed before some exercise in the park?
