I've been smoking weed for 35 years almost every day. I grow my own supply about once every 5 years. I have been smoking about 5 ounces of good weed per year. I use a water pipe and carefully conserve my stash, about 10 to 15 tokes per day, and I only smoke alone, that is why it lasts so long. I just harvested a couple of plants that are sooooooo potent that I think I can cut my usage W A Y back to just TWO tokes per day of Northern Lights #5 or Super Skunk. I am eager to try my Mr. Nice X White Rhino.
