I don't think discord is a valid replacement. One of the best parts of reddit was the easily browsable/searchable Forum like threading. Where there are communities for a given theme, and threads branching off of that group. Discord is great for realtime chat, but a significant pain for async conversations. In general for information access I personally don't like to search through chats because the threading is too shallow, and conversations are had at the root, aka group level.
I'd argue that the chemical withdrawal effects of marijuana, are nothing compared to habitual smoking, alcohol or other "hard" drug use. But there are still some chemical withdrawal effects.
Personally I've had Minor irritability after not having an edible for a few days if I've been consistently having them nearly daily for few days. But I've also realized this, and moderate use more to only once or twice a week, and only 5-10mg at a time. I've grown to like the feel of 5mg in the evening overall. Accounting for the blah feeling the next morning/day.
