Good morning family, we just need your opinion, reactions and answers to this. My very close girl friend is going out with another of my friend, a "guy" for about five months now. She stumbled on a pack of tablets called "Isoniazid" in the guys room, texted it to me. Yesterday, I goggled and found out that the said tablet is used for "Tuberculosis" treatment. Now my friend is wondering if it's okay she ask or talk to this guy about it. But we are wondering what his reaction would be like? Admin please, notify us as you post this.
