Because the ROA is of such importance with this substance, I want to share my recent "upgrade" to a ceramic atomizer with a mini coil. I am not affiliated with the company and am not plugging this for gain, but for sharing information.

I've tried changa, glassware, pipes and vapes with juice mixtures and pretty much everything in between. It all worked somewhat, but I definitely wasted a lot of spice in the process.

I've been reading much about the dab/wax gear and have just bought a kandypen prism on sale for round 50 bucks. Considering how much spice I've wasted, I figured that 50 bucks would be a really good investment, if the gear did in fact work well.

And it does!

You can load the freebase straight into the atomizer and vaporize it on the lowest setting.
It does take two or three consecutive hits for the entire chamber to vaporize, but wow, what an improvement over all other ROAs I've tried. Just pre-melt the spice with a few short intervals of firing the chamber and then go for a 5-9 second burn. Then another one...and bye bye Alice.
