I only want to use about a 1/8 of high quality bud for some butter, how much butter should I use? Also what is a good amount of time for it to simmer?

two sticks of butter simmer on low for 30 minutes, stir ocassionaly.

Remember to do it on a LOW heat, just let it absorb the thc and strain out the mix after a good while. Make sure you do it in a clean newish pan, heard bad things about black stuff coming off pans and stuff.

How much butter do you suggest for a nice, non-mind bending high?

...just experiement.....

as a rule of thumb its 1lb of butter to 1oz of weed
