Toxic, clay sulak up in Maine is a good dude who does testing thru interg8. They're just one of the doctors practice that hands out medical cards. I know there are few other places in mass and rhody too but I would have to say I trust clay the most mainly because I've met him personally and shot the shot with him and he is educated, knowledgeable, honest, passionate about the plant as much as us. Hit me up he need more info.
