as far as making hash goes
traditionally, hash is made with parts of marijuana plants that arn't normally smokeable. When you smoke weed, what your smoking is the bud. To make hash, you need leaves and stems from the marijuana plant that contain small amounts of thc. You also will not some sort of extraction tool, the best is a bubblehash bag ... hash can also be made if you have like alot of shitty weed...

hash is good if your a grower... you get the most out of your plant

and as far as vaporizers go, vaporizers are great! Unless you buy a cheap 5.00 one, they are supposedly just as good as smoking. Many medical marijuana patients use them. they produce a bit more of a headhigh for some reason though... and they get every bit of thc out of the bud....
