I'm not speaking from experience or anything. Nor about the "dark" trip reports. I'm talking about the stories of addiction, permanent debilitating brain damage, and death.
It's pretty fucked that LSD, psilocybin, and THC are schedule I in the U.S. while this shit doesn't require a prescription.
(Not that I think DPH should require a prescription. More that psychedelics like LSD and psilocybin should be accessible recreationally.)
Here in Belgium, even ibuprofin needs a prescription. Certainly DPH.
Then again, here weed is still illegal (possession of 3g decriminalized) and the actually very beneficial stuff like LSD and psilocybin are also highly illegal.
I've never had a brain fog like I have when I briefly abused benadryl as a regarded high schooler whose parents drug tested him. DPH is a pretty severe deliriant and you will lose your short term memory for as long as you take the pink pill. The hallucinations are kinda fun though
You shouldn't be taking deleriants if you want to see some shit. Never done it myself but I've heard that the hallucinations are so vivid that you can be convinced they're real. Hard pass for me.
Take psychedelics instead. At least on those, you're aware that you're tripping.
Benadryl has been a brand in the US for decades longer than Cetirizine has even been in use, and they never changed the active ingredient when new antihistamines became available. Good thing too, cetirizine doesn't do shit for my allergies compared to DPH, and most other allergy med brands use cetirizine.
