Wrapping the hash tightly in light and airproof plastic and then freezing it is the best preservative measure that can be taken. A small piece is quickly thawed for smoking by holding it in the closed hand. I have come up with a good method for smoking hash oil in case your readers may be interested. I take a glass mason jar (cannabis zaden) and drill a hole through the bottom. Then I take a piece of aluminum foil and place some oil on it. I then wrap the foil across the opening of the jar with the hash oil on the inside. Then I invert the jar and hold a flame under the foil in the spot where the hash oil is at. When the jar is filled with smoke, inhale through the hole in the bottom of the jar. Also I would like to say that I am well satisfied with the results of the Isomerizer.Is the procedure for making lettuce “opium” any different than a normal oil extraction? Also, what is the best way to smoke the stuff?
