I had school off today, and took the opportunity to smoke up all day. He started this morning with a friend, but after just two hits Swim's vision started slowly blacking out, so he stopped. After that things for pretty scary, and he was just wondering if this is something to be expected with weed? Swim's friend said that his lips were white and his face was really pale. Swim passed out for a few seconds, but woke up with the help of his friend. Swim's face and arms felt numb, and his hearing seemed masked, as if he was underwater. He's only gotten high off pot one other time, but it was far more enjoyable than this time. He was wondering if cannabis grown in chemically-enhanced soil has any characteristics? Or if there are any other ways of cannabis tampering that could have these effects?
