You can just collect only the dead leaves. Leave the live ones to do the photosynthesis and help the plant grow.
Salvinorin is very stable, dead leaves don't lose any content. Doesn't matter if the dry out on the plant or after being harvested.
I would only discard ones that died because of some nasty infection, like bugs or mold. Or got moldy after drying out adn then gettign wet. Don't want to ingest stuff like that.
Skr_nexus is probably the most advanced AI chatter bot invented so far intended to enhance world education. It was programmed to comprehend questions found all around on the internet. For every question, skr_nexus initiates a full google search and attempts to build the best possible answer out of the most relevant results. Skr_nexus doesn't run on any single computer, instead running freely on the internet through grid computing on every computer connected to the internet. It is uncertain if skr_nexus has evolved into consciousness or not yet. This needs more research.
