This is a difficult question. Some will say yes, others will say no. Some had experience with psychedelics before they tried DMT, others did not. We're on different paths, and the path of one does not define the path of the other.
I think you would do wise in following your own inner voice on this one friend. We can give you advice, but it is just that, based on our own experience and our own thoughts on "how it should be done". There is no definite answer the way I see it. But I can tell you this, and this is a fact: DMT is very short if smoked, so you will come out of the experience very quickly. This, among other things, should be taken into consideration before making a reasonable decision. Gain knowledge, and make your decision based on the information you've acquired and what you feel is right.
