I don't think it's that freaky. When I used to buy bud instead of raising it, I would recycle my hits in a balloon, meaning I would inhale the same cloud of smoke 2 or 3 times. people were often disturbed by it and thought me a weed fiend, but it wasn't that I was stoned all the time and needed to suck down as much as I could to stay that way, it was a method to save half of what I was spending on bud. eventually I learned that you could economize just as effectively by taking a much smaller hit and holding it in a normal amount of time. mostly only works when you're smoking alone though. but if I had a vaporizer, I would never be concerned with conservation
