I had used it very recreationally when I first found it.  I was still going through my "let's try every drug" abuse type phase and me and several friends used it over and over and over and over for days on end in breakthrough doses and trips.  Later on we all got kicked in the ass by hyperspace for this. Now we use in deep respect of the spice, and are far more responsible in our dosages, integration, and the like.

But just wanted to say it is possible, and at this point there was also several other not friends but like acquaintances who were also using recreationally, so give the worlds irresponsible kids some credit ;P  they can abuse and use almost anything recreationally.   

And welcome to the Nexus Realms Undiscovered.  This is the first web forum I've joined for kind of similar reasons regarding the respect, trust, and helpfulness that this community demonstrates.  Theres lots of aya information all over the threads here, I'm sure you can find some awesome info by searching for Ayahuasca and spirituality or similar terms. 

Best of luck in your journeys and I look forward to learning with you as continue on down the DMT path.
