30 mins is just way too short!! ... put in the effort lads if you want the results ... boil it for at least 5 hours ... after 3 hours of simmering the butter changes colour ... after 4 hours its nearly done and 5 is just to be sure ... and during the process if you have a strainer dont be afraid to gather up the bud and sqeeze the feck outa it and then put it back in ..... you want to release all the thc which is sticking to the leaf matter

Then at the end make sure the water/butter is just hot enough not to scald you but not luke warm ... and SQUEEEEEZE every last drop out of it and then come back and post how fucked up it gets you

If you using non spent bud then 0.3 per person is enough to get you whacked for about 6 hours ... ive a high tolerance but cookies and my volcano gets me sooo stoned

So if you put in 2g of bud and say 10g of spent volcano bud ... and you get 30grams of butter back then just class that as around 3g of bud so do the maths (10g butter = 1 gram bud = 3 mega strong cookies or 5 medium cookies) Give it at least 40 mins to kick in ... eat on an empty stomach if you can and it will get into your blood quicker

enjoy
