How would you react and would you get mad if your 18 yr old son or daughter wanted to take enhancement pills.

If your son wanted to take them to make their you know what bigger.Or if your daughter took pills that made their breast and buttocks bigger,especially since it’s popular in music videos,music video girls and people like Nicki Minaj.And they’re 18 or 19 yrs old, would you really disapprove?(This question has nothing to do with me, just to bring a topic up).
