There's too many factors on the table to just label right away DMT as "recreational", the way most people will understand the word. As in, taking DMT basically for relax, fun or pleasure.
If we think of subbreakthrough doses, I'd say it can be faced recreationally. As for higher doses, I think The Traveler drew fast enough up there and shot the #1 point for me.
Of course I cannot speak for others, but once I got an idea of what can be found inside DMT, the fact my experiences so far have been pleasant hasn't changed a bit my attitude towards it. No matter how cuddled I felt in that moment, or how dazzled I was looking at that, I don't think I could take DMT mainly to relax or have fun in doses larger than low. It CAN turn out very fun. But even if you have done a little homework and have an outline of what to expect, every time you try it, all bets are off.
Pleasure, however, is a different word... there is this buzz of excitement, like exploring a new world with rules you don't understand. Like Marco Polo deciding to change course, heading underground and finding a dimensional portal. And he has to leave the camels, maps and bearers outside and cross it wearing nothing but his thighs.
So for me, medium+ DMT doses can be used recreationally if you know having your reality reprogrammed turns you on, if you enjoy the unknown, if you don't mind having to fight the dragon now and then. But it takes a badass psyche to do that... and please don't read that as a fraternity challenge, but rather as an invitation to accept the fact that most of us are not that badass.
given DMT to smoke could be far more potentially disturbing or traumatic for some than any of the substances listed in the OP as 'recreational' - the Definition which began this thread.
