Tell people marijuana isn't even so bad for you and actually makes life more satisfying. An idea from Robin

Yes! A smoke now and then in the year is lovely!

But it is not good for your health (especially when you smoke it) and a lot of crime exists in the process of growing and trading. So i believe we should legalize it (to get grip on growth and trade) and then should tell everybody how bad it is for your health. Same thing as with sigarettes and alcohol.

Then don't smoke it? I always eat a nice cupcake!

Ps. think more abstract, and for yourself.
pps. lungs LOVE weed!
