Just to demonstrate how well suppositories don't cause euphoria (and for general amusement) I'll share what happened last Saturday.
I take 5 doses of 135mg CCO a day rectally. Some times I take a double dose. Saturday night getting ready for bed, I had my last dose (single) of the day in one hand and a glass of water in the other. Out of habit I popped the capsule in my mouth and swallowed. I didn't think much of it, because at lower doses I often took one orally to help me sleep. I didn't think about the fact that I had upped the dosage quite a bit since then, or that this batch didn't have any CBD in it. I went to bed as usual.
I woke up 2 hrs later with everything spinning, vibrating, I think I saw lights blinking, or maybe that came later. Eventually got feet on floor, sitting and wobbling on edge of bed. I wasn't panicking but I was more than a little concerned. Then my heart felt funny. Actually my whole body felt funny, but my perspective was a little off. I had a really high blood pressure reading the day before, which is what I focused on, forgetting that the first reading was probably an error and second one was normal.
My concern escalated and I woke my wife. I managed to form a few words. Pill... swallowed... heart... there may have been more words, but that was enough for her to call 911. I tried to stand up, heard stuff crashing, found myself on a pile of laundry. I couldn't even crawl. My wife had to hold me up while I slid my legs. Got to the stairs. Slid down the stairs to middle landing, which is where I was when medics arrived.
A medic propped me up to take my blood pressure but I fell over. He tried again but couldn't get a reading because I kept falling over. Finally managed to stay up, blood pressure was normal, pulse normal. Hearing this relieved my concern and suddenly I could think more clearly even though I still couldn't move or speak coherently. I knew I'd be fine in a few hours and actually enjoyed the feeling a little between waves of going completely blotto.
At this time I realized I could smell the harvest drying in bathroom 10 feet away. Also noticed medics smelling it, looking at each other but not saying anything. My grow is mostly legal, but I didn't want any follow ups. My attorney had advised me that in my situation I wouldn't be charged but they might take my extra plants.
When medics said I should go in for observation I resisted at first because I knew I didn't need to, I just couldn't express that clearly. I probably came off like a totally blitzed drunk saying "I'm fine, I'm fine." I don't think they believed me. So I went with them to avoid trouble and follow up investigation.
The upside is that all of the tension in my back that had been giving me pain for weeks. But I don't recommend my experience as an appropriate treatment for back pain.
I hope you all found this amusing as I look back and laugh at myself.
Back to the issue of suppositories. I took double dose rectally of the same capsules about an hour ago. I feel a little tingle, a touch of cloudiness in my brain, but that's it. No euphoria. Suppositories work great for avoiding euphoria.
