Some common terms for cannabis are actually the names of the species. For instance one of my favorites is "Blue Cheese". I prefer to use cannabis for general reference, since marijuana is slang.
You can roll your cannabis into rolling paper, and smoke it, some of the kids like to use blunts. A blunt is a cigar rolling paper. They also make flavored papers but I personally dont like the taste of the burning paper, I prefer the taste of the medicine. My PDS (personal delivery system) consists of glass sherlock bubbler, and a glass bowl for on the move. Each person can make their own choice after experiencing various methods, which is part of my consulting services.
