DRIED CANNABIS FLOWERS
Intact terpene profile, imparting a more unique effect; generally more variety at retail outlets; quality flowers can be processed into edibles or even homemade extracts (extracting oil from cannabis flowers is often a very volatile process, and should only be attempted by professionals)
You need papers, at least, and ideally a pipe, bong, or vaporizer of some sort, which aren't cheap if you don’t want a piece of junk. Burning flower has a strong, distinct, and difficult-to-manage smell, which can linger for a surprising amount of time. Bad for apartment living.
