You may also use cheese instead peanut butter and make a "cheese-cracker"... or change also the crackers for bread and make a "cheeseweed"...
Remember that (as happens with eaten weed) the weed must be activated first. Just heat it some time in the microwave and its done. The time varies between 30 secs to 2 minutes. After it, the weed must be dry and crunchy. Grind it to a fine powder (the finest you can) and put it in the firecracker (or sandwich or whatever you were to put it into).
One gram of good bud must be more than enough for a very HIGH high, if done properly... so, good luck and have a nice HIGH! :thumbsup::rastasmoke::stoned:
