Put your stuff in those tiny ziplock bags - they hold maybe a gram or so - and dole it out to yourself over time. You could freeze them, so it would have to thaw out before you could smoke it.

Small amounts are fine, like a quarter gram or less a day. You just have to get used to it. I know that some people are laughing at this. I used to be the same way when I was younger, when I didn't conserve weed. A couple of tokes, once or twice a day, can be very satisfying for most smokers.

Using a vapor pipe or vaporizer is a good idea, also.
