Okay, here's what you need to know:
First, it's not only a specific species of toad as you may or may not have heard, in fact all toads (let's not confuse frogs with toads, here) contain the drug.
Second, its easy as fuck to smoke that shit, you simply find a toad outside somewhere, kill it, skin it, and leave the skin in a dry place with plenty of fresh air to dry. Next, you just smoke the skin! I do it all the time and it is wonderful.
Also if you want a longer duration you can just chew on the skin for 20 or so minutes making sure not to swallow any saliva until after the 20 mins, works great this way! I find too that the skin actually tastes pretty good, kind of like some good jenkem.
But seriously:
5-MEO-DMT will rip your soul into two, drag both parts through hell and then just maybe bring you back to life. I'd really consider you look into 5-MEO-DMT before you go and try it. Powerful substance.
And don't hurt the fucking toads

Bufo alvarius is a rare and endangered toad and they are illegal to posses in some places. Maybe it doesn't particularly hurt them but it sure as hell can't be fun, and it's pretty cruel IMO.
