Weed backfires mercilessly for some, causing the uncurable chronic illness Cannabinoid Hyperemesis Syndrome. My family member suffered undiagnosed for 4 years after starting medical cannabis use for pain. It ruined her young life, making school impossible due to multiple chronic symptoms (about 20), including severe anxiety and depression. Weed is super strong these days and it's killing people. Weed culture doesn't like to hear this, and many ER doctors are oblivious to this epidemic.
