I was very curious on this, as I've been looking through many sources to no avail. Please don't take my post count negatively, because I'm not a veteran to anything of these sorts. I'm unable to post a photo of the glass blunt as I'm posting this through a mobile phone, but it's just two pieces of glass tubing that fit together that would act as a simple reloadable cigarette. If such a method would work, would a brass pipe filter help the cause as well? Thank you for your feedback!

I'm sure you could stuff it with a bit of scrubber and smoke it like a 'one hitter' crack / meth pipe, but something tells me it might be quite harsh as the vapor is travelling such a short distance to your mouth / lungs. Ideally you want to heat the Spice gently and a chamber is advantageous for larger hits, which is why bongs are often recommended. Alternately, something that diffuses the heat, such as a Vapor Genie is also ideal. If you try it then make sure you report back, it may take some practice to get right.
