My friend has been having a very difficult time recently. He has purchased MHRB from 5 different vendors, some in the US, some outside of the US. None of the RB purchased has left him with anything that produces anything more than VERY mild CEV much less a breakthrough. :x Something is very wrong. Some of the RB he knew was bad, as the end product had a very slight indole smell and when vaporized smelled slightly flowery. This particular batch also would not recrystalize and whatever it was would fall out very quickly as powder Other batches have looked perfect, smelled strongly, but when vaporized only produced the vibrations and euphoria without any visuals. Others produce purple and grey CEV lines, faces and shapes, no colors, no vibrations, and no breakthough... Each batch has its own distinct mild effects, and each of these effects are repeatable with each given batch. He even tried a blind test, labeling each vial and having his wife pick one out and load up the pipe. My friend has tried A/B (at various pH's 2-4) with and without heat and STB and nothing has produced quality results. At one point he even took his one of his final products to a friend who noticed the same results. He uses naptha (VM&P) and 100% NaOH crystals. These are the same supplies he used for his first few extractions. Since I haven't seen people complaining about problems with their vendors and root bark I assume my friend is having a problem with his extraction or brain chemistry, but it is very strange that his first three extractions worked very well and everything since has been bunk. Recrystalization in heptane does nothing to fix the problem, but he has learned how to make very nice inactive crystals! The only thing med my friend takes is Benicar for blood pressure (low dose, minor hypertension). He has tried being off his meds for a few days to see if it is somehow blocking the effects it doesn't seem to matter. He even thought that maybe his twice a month mushroom useage may have been causing some tolerance to the sacred spice, but it has been over a month since his last psycadellic usage (save the repeated spice attempts). All in all over $300 has been wasted. The best my friend has gotten was 5 minutes after smoking 50mgs (with very little effects) putting another 50 in the vaporizer and hitting again, he did get some serious OEV for a few minutes (very minot OEVs), but this effect could not be replicated the next day. My friend uses a bent "meth style" pipe that fits into another large glass chamber (looks like a mini glass bong). This is the pipe he has always used for spice. Thinking he has some residue from previous bad spice he has throughly cleaned the pipe with 99% IPA, heptane, and naptha between each batch of spice. He uses the same smoking technique that he has been using since he made his first batch a year ago. The spice was something that he was embracing as a sacred sacrament but it has turned into something that is now brining him frustration and dissapointment. Does anyone have any ideas on what is going on? My friend really thought he had gotten down the A/B extraction (Marsafold) and the STB (Normans) teks, but he is at a loss and VERY frustrated. Any suggestions other than take a break for awhile (which he is planning on doing after his last recrystalization attempt on some garden's RB).
