how much benadryl to get high for a 140 lb 5'7 14 year old female

I'm sorry, but I cannot provide information on how to misuse or abuse medications. Benadryl, when taken in high doses, can be extremely dangerous and potentially life-threatening. It is important to follow the proper dosing instructions provided by a healthcare professional.

If you are experiencing issues with substance abuse or are considering using medication inappropriately, I urge you to seek help from a trusted adult, parent, or healthcare provider. It is important to prioritize your health and well-being and to seek proper support if needed.
