Hi there and welcome!
Firstly, 0.65g from 50g bark is respectable enough.
Strange that the bong sandwich method didn't work for you. How long did you hold the smoke in? Have you used any other psychedeic substances, and if so, what kind of dosage range did you require?
Have you checked the
Vaping/Smoking subforum? And the
First steps in Hyperspace subforum? And of course, over in the
Welcome discussion subforum, we have Anrchy's indispensable
DMT vaping guide as a Sticky thread right there near the top.
While I can't specifically comment on the dabber due to lack of experience, I do wonder whether you really mean smoke, or if it was vapour you were seeing. The point is to vaporise the DMT, which requires an element of fine control. When you get it right it should produce thick, white clouds of vapour. It should be
relatively comfortable to inhale, and have a broadly acceptable flavour - although this last one is admittedly somewhat subjective.
Also, I thought the whole point of using a dabber was that you heat it up
before placing the substance on it for vaporization.
Another thing you might want to consider is using some form of
harmala alkaloids which would then considerably broaden the time window for dosage and smooth the ascent. [Importantly, we have to emphasise that there are
safety aspects which must be adhered to when using harmalas.]
“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli
