I can attest to this. I smoked changa once a day for 3 weeks, building a relationship and familiarity with it, slowly increasing the dose. By the third week I was smoking rompa cones and going deep. I thought I had reached the pinnacle of the experience but was wrong. It was the final and ultimate time of smoking the changa. I packed a rompa cone in a peace pipe and sat and meditated for a while. It was night time and I was sitting outside in the dark. I feel asleep for maybe 30 minutes, tired from smoking the changa earlier that day. As soon as I woke up I remembered I am smoking changa. Picked it up and took one big breathful and hold it. It's the primer and all the usual phenomina that I'm used to. The next breathful took me over the edge into breakthrough, which all the previous experiences could not prepare for. I was confused and legit thought that I had died. Needless to say I got the experience I was hoping for. The thing is with micro dosing or begining the journey, you know what the eventual outcome/destination is going to be... like an addict it's going to be overdose or rock bottom.

I had PTSD afterwards for years. A song or a situation could trigger a dreadful feeling. I could'nt use mind altering substances for years. A honest days work, sraight and sober and a good nights sleep was mind altering enough.
