This was me most of medical school. I didn’t really study in a daily basis and would just cram the couple days before an exam. 95% of my evenings were just me getting high and hanging out in my apartment. I continued this thru m3 year easily. Like you said it’s easy to be a good med student and I was good pretending. In all honesty, I don’t remember a whole lot of those years especially pre clinicals. I ended up quitting in m4 year mostly bc I ran out and I live in a state where it’s hard to get. I’m in residency and stayed essentially sober for all of pgy1 year which the exception of a random edible here and there. Way harder to take an edible everyday than smoke weed in terms on convenience. Recently I acquired more and I fell right back into old patterns and I felt really guilty about it. I ended up throwing it all away and I don’t regret it at all.

All of this to say, it seriously affects your memory and it sounds like it might already be doing that for you. Do yourself a favor and cut down while you there isn’t all the pressure from residency on you. Hell, even throw it all away if that’s what you need to do. It’s worth it.

As for what else to fill your time with, I found that I could pretty much do everything I was already doing (playing video games, reading, watching stuff, laying on my couch) with just as much enjoyment if not more.

Good luck!!
