stronger fire crackers

so i attempted to make 3 fire crackers with around a little less then 1 g of mids, it had seeds, big dark ones and it was good smoke, (had about an eighth) thing was for mids it was a nice green, when i first saw it i thought it was oregano but it wasnt, thing is i used my grinder and they came out perfect, all right portions, 23 mins nuttella wraped in foil etc, they only lasted for around 3 hours, is there any way i can get stronger more longer lasting firecrackers with jsut mids?

and i was wondering the high was really diffrent, like it wasnt a very couch locked at all, i was more energetic and then when it died i had no crash i was jsut abck to normal perfectly.

when you guys eat fire crackers do you guys get couchlocked?

btw i still got the *close your eyes and rub your eye lids, see crazy colors* effect hehe ;)
