So I stumbled upon this the other day. I still don't have a name for it, so please leave your suggestions.
First you roll a joint as you normally would. Then, put the joint in one of those resealable super-minty chewing gums, like Airwaves, for example. Generally this kind of gum has eucalyptus and menthol in the candy coating. Menthol and eucalyptus are widely used in medicine to clear the head and nasal passages tend to reduce the symptoms of nasal congestion and colds. Leave the joint sealed up in the pack, with or without the gum, for at least a half a day, or better yet, for several days. When you smoke the joint, you will experience a cooling sensation in you mouth, throat, and lungs, similar to a menthol cigarette. It's a surprisingly pleasant new way to smoke your favorite strain of marijuana. Give it a try, and let me know what you think.
