Could you use leaves and.....

just have a marijuana salad? Put some dressing and maybe carrots or something but just use mj insted of lettuce?

Yep, you sure could. You wouldn't get the slightest bit high, but you should poop easily the following day.

i've always wanted to make a salad consisting of big marijuana fan leaves, sliced hallucinogenic shrooms, peyote buttons, sliced peruvian torch, with a greendragon for salad dressing

Hm, you might die. That'd be interesting though. Haha.
