Yes, I have seen a 3 leafed Medical Plant.

It comes not from a leaf, but the bud of the Cannabis sativa during its flowering stages.
Hemp Flower plant and marijuana plant both are same species.
The plant is probably dying
Depends what country you are living in
Marijuana is not in any plant - it is a plant. Cannibus Sativa is the 'Marijuana Plant'.

Just by drawing it. Look up images of a marijuana leaf and copy what you see.
either a maple leaf or marijuana
No. You don't actually smoke the 'plant'. There are female and male marijuana plants, males simply grow leaves and can pollinate the female, and the female grows the buds, which you (or people) smoke. When the female plant grows the buds (which contain the THC that creates the desired high), they can be picked and smoked immediately. But you don't smoke the actual leaf of a marijuana plant. Hope this helps.
Leaf is a plant.
Bird of paradise is a tropical plant. Hosta is a plant that grows from zone 3 to zone 9.
