First time high from eating pot?

Iv been wanting to get one of my friends high for a while but he won't smoke but agreed to let me to make him firecrackers. I didnt get high my first time smoking so im not sure if he'll get high his first time from eating pot. Do you guys know if this matters, if he should eat more, or eat less due to low tolerence?

just make sure that it is cooked tight and don't put too much pressure on him to feel high, don't keep saying "are u high yet?" if it dosen't work the first time it's straight he still got somethin 2 eat! naw let him eat as many as he wants but be careful, he's more likely to see or hear things fro eating weed than smoking it

it also lasts longer so tell him to clear his day
