Whatever you do is completely up to you and what you want to accept. If you are coming to DMT for healing, there is much to learn, but to me the lessons (experience) is one of the absolute most intense out there, so no need to be in a rush if you are inexperienced. I've heard plenty of reports about smokers who had not tried any psychedelics before, and came away with a beautiful trip.
But I'm looking for healing, and joy again, and need to work on issues of fear, anxiety, doubt, etc. Me personally I would rather experience some time with Cactus and Mamma aya before I start diving into spice breakthroughs. I've seen enough to know for now, and I think I could maybe relax into it, but I'll get comfortable with something 'easier' first. Less steep a rollercoaster anyway, less shocking. I don't expect to be prepared for DMT breakthrough, but I do expect to become a bit more satisfied with life and active in my creation here. .My 2cents
Edit: Note, I don't mean to sound simple, oh, I'll just take this and I'll understand it all better. Not the case. Through any psychedelic use I'm just looking to shake things up some, and maybe see more about who I am and how I feel here.
