A vaporizor high is definitely different. Its a much cleaner, up high than smoking. Plus you tend to not get burned out. I can get seriously high from my vaporizor in the morning and later that day not be burnt at all.

I get the munchies with my vap but don't get red eye.

There is little smell with a vaporizor. There is a bit but it quickly goes away and doesn't smell anything like you're smoking weed. If someone walked in after you just smoked a fat joint they'd know it. If someone walked in after a vap session they might notice an odd scent in the air but no smoke or heavy weed smell.

If you are going to get a vaporizer get a good one. The first Vap I bought was one of the BC Vaps that I got off of E-Bay and it was a piece of shit. It got me high but wasn't efficient and I ended up using a lot more weed than if I smoked it. I actually ended up throwing it in the trash. Now I'm using a Vapor Brothers and it works great. It cost me a $150 which isnt cheap but isn't $300-$500 that other premium Vaps like the Volcano cost.
