i just bought a Oxygen Mini, and i'm asking myself the same question (is it worth it?). as other threads have mentioned, it's a different kind of high. i'm new to this so my technique may be completely wrong. but so far the kind of high i've been getting is the kind where you're not stoned.

i use really small amounts, which were enough to get me a GOOD buzz by smoking. when i vape it i always seem to be checking with myself to see if it had an effect. anyone else feel this? i do get a nice heady feeling,and i do have more energy,but i've never come close to that feeling that it takes all you concentration to maintain.

i don't get the obviously noticeable vapor like on the uTube videos. this is most likly because of the small amount i put in.
i did try it with more herb, and it worked better. i probably got about 10-12 hits, but i still didn't get toasted, felt pretty good though. then again i used more than i would have burned.

before i got the mini i was using a light bulb, and that worked real good, but i suspect that's because i was accessing some of the toxins we're trying to avoid.
