Go to the Recipe forum on this site. All you have to do is find a brownie recipe, and reduce the amount of ingredients to make it 1 or 2 servings. It takes some basic math skills to figure it out.

I suggest you make some basic firecrackers or a drink. I'm thinking firecrackers would suite you best. They're very easy to make.

You need:

-Organic PB. Jiffy brands won't work as they are low in trans. fat. You need a PB that has a very high fat %, without it, you won't get high.
-crackers (salted are fine, 2 of them)
-Oven (preheat to 130-170degC.

Grind up cannabis fine, and mix it in with about a Tbsp. of PB. Spread it on either side of the crackers, wrap in tinfoil, and put in oven for 20 minutes. Eat up and enjoy.

Oh yes, you will need about .7-1gram of cannabis.
