I've been smoking fentanyl for a few months. I've noticed after your gel evaporates you are left with some black gunk in the tin foil. If you continue to smoke this it puts off some smoke. After inhaling that smoke I get a really really big rush and then I get real dizzy almost to the point of passing out. I try to avoid doing this but it gets me higher than smoking the fresh gel. Does anybody know why this is and has it happened to you?
