OK let me make this clear to all stoners out there resin is not and never will be TAR.
Resin is the OIL that comes from the smoke.It looks black but it is dark brown.
The more times it gets heated the darker it will be.When using a lighter such as a bic it will also get darker.When a bic is burning(or most any flame for that matter)it gives off a black smoke.when inhaled through a cigarette,bowl and bong it collects in the lungs(also what it was inhaled through)Thats why vaporizer smoke resin looks almost like sap from a pine tree.(Becuse of the low heat and the absence of the flame)The smoke is in fact exactly the same as the weed it came from if its vaperised resin.Resin is just as harmful as smokeing green weed and by harmful i mean harmless.
