I've got loads of little things i do when it comes to smoking weed. I pray to Jah before i smoke, and afterwards, i rub some of the ash into my left hand.
I always make sure every little bit i've ground up is the same size, and i always tap my grinder exactly 10 times to get some of the kief out to put in the joint.

I've got quite a few more - but most of them are for smoking with other people, and how i roll.
