I'm not sure if I'm doing something wrong or just not using enough weed.

I've tried making cannabutter before but it's a ton of work and all I get is a mild buzz. I'm experienced smoker with high tolerances but people have said that this shouldn't be a factor with edibles because the active ingredient is different when it's processed by your liver. This doesn't seem true on my experience.

I don't care about taste - I just want to get high. Yesterday I made 'firecrackers' with 1g of grinded bud that I had decarbed in 120C (240f) for 40 minutes. I had it covered with foil and was monitoring the temperature with electric thermometer. I then sprinked this on top of a cracker with peanut butter on it and covered it with another one. Again - after an hour I realized I was somewhere at [3] which I could've achieved by just smoking a joint with half of that amount of weed.

What gives?
