Should my girlfriend go clubbing?

Well im 18 and she is only 16. She wants to get a fake to join her 16 year old friends clubbing and this concerns me. I hate that environment where people are doing drugs left and right and running the risk of a guy hitting on her or her or w.e. There are like 21-30 year old men in there anyways i find it a little scary. Anyways i would rather her not go but i dont know how to explain it to her so she can understand me and me not seem "controlling." Thank you
