here is an answer I snatched from reddit
Plugging is my preferred administration of pills and MDMA. Dissolve around 80% of your preferred oral dosage in warm water/whatever your substance is soluble in, draw into an oral syringe, and insert into your rectum. After pressing the plunger, lay on your stomach for around 10 minutes so that it can onset. It should come on just slightly slower than snorting, and be a bit more potent. It is about as safe as snorting, however be sure to lubricate the syringe to avoid tearing of any sort. As for the long term side effects, it depends on the substance and it's fillers, as well as how caustic it is."
So plugging stuff like Bacopa Monierri for instance would be dangerous as it is notorious for heavy metal toxicity. On the other hand, Lion's Mane could be a safer option.
Still these waters look shady stay safe people...
A second chance? Huh... I thought I was on my fifth.
