dans un episode des Simpsons Lise tombait en amour avec un jeune adulte activiste pour l'environnement et il dit: je suis vegan niveau 5, je ne mange rien qui produit une ombre
I think your getting vegan and straight edge mixed up together.
Vegan = no animal products
Straight Edge = no alcohol, tobacco and drugs
Just because your vegan doesn't necessarily mean your edge and vice versa.
I was refrering to medical drugs. And no, vegan isn't the same as vegetarian. Watch anything from Gabriel Cousens if you want some education on the subject. A bit extreme but still educational if you can bypass the peddling arguments.
