I've mixxed cactus tea resin with shrooms. Best combo ever, always eat my shrooms and cactus about the same time. Right as soon as you start peaking on shrooms the cactus will start to kick in (cactus tends to be really sneaky onset at an hour and a half for me.) This combo will make you super lethargic with a nice fuzzy body buzz, has some of the most wonderful flowing visuals as well.
Another reason this rocks is because if i go all the way with mushrooms i feel like demon entities are spying on me, if i go all the way with cactus i puke my guts out. This combo allows me to trip face without puking or fearing for my sanity.
I have a couple of foot worth of cactus resin and a mushroom chocolate that i've been saving for the right time. Best for a solo trip im my opinion, it's a very gentle combo that should be enjoyed with nature.
The downside to this combo is bloating from eating dried mushrooms and cactus extract. Best to consume these on an empty stomach, once i ate them after a large meal and i looked pregnant from all the trapped gas. Peppermint tea will help unplug with the quickness and gives very relieving and entertaining mega-farts.
My suggestion is DO IT
