check out the thread in experiences named "how to increase the potency of MJ".

I tried it, and i have to say its DEFINITELY clearer and stronger. Micro a bowls worth for 15 seconds or stick it in the oven @ 325 Fahrenheit in a tinfoil tent for 4-5 minutes (the oven method will start to smell when you come on the 4 min mark). Take this suggestion or leave it, but i am definitely going to do this again, and im sure so will the others who have tried it.

Read the topic, you will see.
