My friend smoked weed for the first time a few days ago. She was ok at first but then started complaining of a headache and nausea. Then she just started throwing up and didn’t stop for at least a few hours. She was all hot and shaky but completely lucid. No one else who smoked the same bud was effected abnormally. She had eaten recently and had no other substances in her system. What went wrong? She says she always feels a little sick when she’s around people smoking weed? Could she be allergic or something?
