If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
You realize that there are pretty relevant differences between tobacco and marijuana other than the latter being "currently fashionable"? (assuming it actually is -- it doesn't look like it's much more popular than tobacco or than it was 50 years ago to me, at least here in [country redacted])
I said "fashionable" not "popular". I have no idea which is more popular, I mean fashionable in the sense of high status.
