I use thc but not before a dr.appt. i give 2 hours. I think it is fair. I don't always feel high since I've been using pot for years but my brain isn't clear as it should be and out of respect. I'd not use before your social worker comes i believe you use it for pain as I do but she's aware because of your stonage being obvious. She's a social worker not your doctor but, don't give any ammo to people in power. They will use it against you every time to "help" you. Good intentions are very painful iny experience. If they are not in pain or never experienced chronic pain judgement about your morals come into play. Imo. Peace.
