Forget Nicotine. Forget Crystal Meth. YERBA MATE IS THE MOST ADDICTIVE SUBSTANCE EVER. Over winter break I went into my parents' tea cabinet looking for a hot bevvy to sip whilst I knitted some psychadelic socks, and I found some weird stuff called "Matte Leao" that they got in Brazil. I steeped one cup and then two cups and then two bags per cup and then by the end of break I was averaging a box a day. Someone make me stop plz.
