I have read all the cautions in this forum regarding fentanyl, but feels he is experienced enough to try smoking duragesic gel. He started with a small bit and kept doing small bits until he felt something. It took more than he thought and the high wasn't that great. I am new to chasing the dragon, as he has only smoked weed in the past. SWIM also had patches that expired a few months ago. I will get new patches soon, so he can eliminate that variable. Can an expert chime in on the proper way of chasing the dragon? I want to know how the vaporize the drug without burning it? How does SWIM know how much heat is enough? I want to know how long the process should take?
