Someone mentioned about anxiety. I've found anxiety seems to be able to manifest itself in heavy chronic smokers sometimes. I'm sure some of you know what it's like to start off with a few hits off the pipe, then you're taking bong hits and it's relieving anxiety and doing it's job, then you move up to kif hash, then bubble hash. you're rolling now... then you're doing a fat gram or two full melt bubble and it's so good. Then you bust out the butane and start making errl putty and before long you're so whacked out and spun it's ridiculous. I've been there minus the butane hash. When this happens I think your best option is to reverse the process and quit. Don't quit cold turkey but smoke less concentrated forms until you are able to quit for a couple weeks or more. Then you can reboot your system. Some people call it a tolerance break. The good thing about these breaks are that when you reboot and start toking again you can move to vaporizing. Vaporizing will be satisfying to you then. Good vaping gets me higher than smoking, but I was unable to know it until I quit smoking. If you've damaged your lungs with too much smoke, vaping may not do it for you. Also I've found Sativa abuse can lead to anxiety. You know I loved Cindy 99.25, it was such a sublime tropical sativa high oozing with indica resin. I liked everything about it. It smelled like a tropical island, but oh brother, it could spin you out if you started doing full melt bubble off it. Cut it with a pine type indica though and you're good to go. I imagine Vortex as being such a cross.
If you guys are into vaporizing my favorite site is FC or fuckcombustion.com. Great site with VERY intelligent posters and inventors and vaporizer makers. I'm picking up the Hi from TV there.
