I've fucked with all sorts of drugs. Benzos, Gabapentin, opiates, Phenibut, you name it. Honestly, I think the answer ends up being cannabis in the end lol.
Still... DMT was so fucking incredible sometimes. MDMA and shrooms together was probably the most euphoria I've ever felt. I was going completely apeshit bouncing off the walls. The sky was totally dark, the stars were all clear, shooting stars, fireflies, fuck. I want that moment back.
I've still managed some pretty extreme euphoria from weed, but that's usually gonna take a fuckload of Terpinolene in a strain, and that's only found in 1/10 strains (and almost always it's a Sativa like Durban or Jack Herer types). There's just something very unique and different about good weed euphoria that takes a solid T-break to understand if you've smoked for years and years and years without any break like I had.
Either way, DMT is my 2nd favorite substance next to weed.
