Weed-ash
When you collect the black ash from smoking weed in your bowl (Not Resin) and save it until you have a enough to keep you high for 2 days about 1/2 jar.
I have been smoking so much weed everyday/all day that when I ran out for a couple days, I remained buzzed by smoking my old weed-ash... I think I now have black lung, but it kept me from being sober.
