Last time a similar topic was posted it Hacker News it was quickluy closed, though I found it was very useful since it led me to ecigarettes. I'm primarily a cigar smoker. However, I'm now really enthusiastic about ecigarettes. After all, nicotine isn't such a bad recreational drug (aside from the addiction). The harmful part comes with the delivery. Now, I can smoke while I work and reap the benefits of increased concentration without the negative smell and health issues.
You're talking about those "e-cigarettes" right? How do they compare to the real deal in your opinion? I've been meaning to try one, but many e-cigarette are costly.
A vaporizer is not a pipe or bong, and it is certainly not smokeless.
You put your combustible material in a machine that heats it up until it smolders, and collects the resulting vapors in an airtight plastic balloon. Then you remove the balloon from the machine, put it to your mouth, and inhale the contents.
With a pipe or bong, you burn the material with a fire, and suck the smoke directly into your lungs. The difference with a bong is that the smoke passes through water first, which cools it and removes some of the heavier debris.
A real vaporizer is certainly smokeless. It vaporizes the oils in the marijuana bud; the marijuana is not supposed to burn. If you've used a vaporizer and it was producing smoke, that means that you had the heat turned up way too high.
That's why I asked. I am well familiar with the ganja vaporizer, but the "e-cigarettes" also act as vaporizer of some weird nicotine chemical replacement for tobacco.
