Although, smoke will always smell like smoke. But I think that it could be genetically modified for the smoke to not smell like pot smoke. Although, if then once this comes to the attention of everybody, any smoke could smell like pot smoke. Interesting. Now I don't think it's such a good idea. Plus, ganja smoke smells wonderful... don't you think so?

Oh, and you can use a little tube and fill it with a bunch of fabric softeners. You blow the smoke through it, and you cannot smell the smoke at all. It smells like fabric softener in the area -- it's pretty fucking awesome. Works really, really well.
