Joint, all the way because of flavor, ease of smoking, and a joint is the second cleanest way to smoke for your lungs
Second, vaporizer. The only reason this is my second choice is its not as easy and convenient as a joint, but flavor, efficiency, and cleanliness for your lungs, its the best.
Bong. Easy. Not as harsh as a pipe, and I love my bong, its 15 years old and burned more green than than the federal government!
Blunt. Reminds me of years past but is no way to treat proper bud where somone took effort and skill to bring out flavors and such. I dont pour coke in wine do I? If Im on the east coast, ok... I cant usually find proper smoke easily , so blunts will hide the flavor of amonium and downy sheets.
Pipe...unless its long and thick glass, the smoke is hot and harsher, and you can get ash and resin In your mouth teeth and lungs. No fun. Not the way to smoke after 10 years because your lungs will start to...dislike you.
